Glossary of Scissor Terminology

A blade shaped like a bamboo leaf with a gentle, subtle curve. This is the most common professional blade shape in Japan because it handles virtually every cutting technique well.

The shape of the cutting edge viewed from above. The blade line determines how hair feeds into the cut and is a primary factor in how a scissor performs different techniques.

A convex cross-section blade profile named after its resemblance to a clamshell. Pioneered by Hayashi Scissors, this is the gold standard for premium Japanese shears, producing exceptionally smooth cuts with minimal friction.

The Japanese loanword for convex grind. Technically similar to hamaguri-ba, but the Western term lacks the artisanal connotation that the Japanese name carries. You will see this on spec sheets from brands marketing to international buyers.

The precise point where the two blades make contact during a cut. The hit point travels from base to tip as the scissors close. Proper blade alignment at the hit point is critical for a clean cut.

The concave hollow ground into the inner face of each blade. Urasuki reduces surface contact between the blades, which lowers friction and lets the scissors glide through hair. The depth and shape of this grind is one of the primary markers of scissor quality.

The blade operated by the thumb. It moves against the static blade to execute the cut. Proper thumb technique on the dōba is fundamental to clean cutting and reduced hand fatigue.

The point where the two blades cross and rotate around the screw. Everything about how scissors feel in your hand starts at the pivot.

A hybrid edge that blends convex and beveled geometry. Easier to maintain than a full convex and more forgiving on technique, making it popular for mid-range shears.

A blade with an aggressive sickle-shaped curve. Used for specialized techniques where the pronounced curvature helps guide hair into the cutting line.

The blade held by the ring finger that stays relatively still while cutting. Also called seiba. It anchors the cut while the moving blade (dōba) does the work.

A two-angle grind with a visible step between the bevel and the blade body. Common on European scissors and many entry-level Japanese models. More durable than convex but produces a less smooth cut.

A perfectly straight edge line with no curvature. Best suited for blunt cuts and precision lines where a clean, even result is essential.

A single-bevel edge inspired by the Japanese katana. Delivers extreme sharpness but is highly specialized and requires experienced handling.

A blade with a long, pronounced curve resembling a willow leaf. The extended curvature delivers a softer cutting action that works well for slide cutting and texturizing techniques.

A three-dimensionally contoured handle shaped to follow the natural curves of the hand. More expensive to manufacture than flat handles but significantly more comfortable during extended use.

A pivot screw with internal ball bearings that deliver an ultra-smooth opening and closing action. Found on premium shears where blade feel is a top priority.

An extreme offset design with a deeply angled thumb ring. Offers the most ergonomic benefit and is often recommended for stylists dealing with repetitive strain or carpal tunnel prevention.

A wheel mechanism built into the pivot that allows micro-adjustments to blade tension without any tools. Convenient for stylists who like to tweak tension between wet and dry cuts.

A traditional symmetric handle where both finger rings are the same size and aligned on the same axis. Named because it resembles a pair of eyeglasses. Some veteran stylists still prefer this design, though it requires a higher elbow position.

A low-profile pivot screw that sits flush with the blade surface. Requires a hex key for adjustment, which keeps the setting from drifting accidentally.

A handle where the thumb ring is shorter or angled lower than the finger ring. This is the most popular modern handle design because it lets you drop your elbow and reduces shoulder fatigue over a long day.

The small hook or tang extending from the finger ring where the pinky finger rests. Provides additional control and stability. Some stylists remove them for preference, but most find they reduce hand fatigue.

Removable rubber inserts placed inside the finger rings. They cushion the fit, reduce vibration, and dampen the metallic sound when blades close.

A rotating thumb ring that allows full 360 degree freedom of movement. Designed to eliminate thumb strain, though it takes time to retrain muscle memory.

A stainless steel alloy enriched with cobalt for improved hardness and edge retention. Cobalt alloy shears typically test between 57 and 62 HRC and hold a sharp edge longer than standard stainless.

Multiple layers of different steel alloys forged together to produce a distinctive wavy pattern on the blade surface. In scissors, Damascus is primarily cosmetic; the cutting edge uses a hard core steel while the outer layers provide visual appeal.

An advanced powder metallurgy steel with grain structure measured at the nanometer scale. Mizutani is the most prominent user, claiming blade smoothness under 0.0001mm unevenness. This is currently the pinnacle of scissor steel technology.

Steel produced by compacting metal powder under extreme heat and pressure. The process creates an exceptionally uniform grain structure that holds ultra-fine edges. Found on premium scissors testing at 62 to 67 HRC.

The heat treatment step where heated steel is rapidly cooled to lock in hardness. The temperature, timing, and cooling medium used during yakiire directly determine the blade’s final HRC hardness.

The Japanese loanword for stainless steel, from the English. Nearly all modern professional scissors use some grade of stainless alloy for its corrosion resistance around salon chemicals.

A deep-freezing step after quenching that converts retained austenite into martensite for improved hardness and dimensional stability. The blade is cooled to temperatures below minus 70 degrees Celsius.

A controlled reheating step after quenching that reduces brittleness while preserving hardness. Without proper tempering, a quench-hardened blade would shatter on impact.

A thin titanium or titanium nitride layer applied to the blade surface. Adds scratch resistance, reduces friction, and is sometimes used as a solution for stylists with nickel allergies.

A high-carbon stainless steel made by Takefu Special Steel in Japan. One of the most widely used alloys in professional scissors because it balances hardness, corrosion resistance, and ease of sharpening.

The deliberate 0.03mm lengthwise curvature engineered into a premium Japanese scissor blade. This microscopic bow ensures the two blades maintain consistent contact pressure from pivot to tip during closure, eliminating dead zones and enabling smooth slide cutting.

The craft of creating the final cutting edge on a scissor blade, combining grinding, honing, and polishing. Hatsuke is performed by specialist craftsmen and is considered the most skilled step in Japanese scissor manufacturing — a single pass at the wrong angle can ruin hours of prior work.

The rotational adjustment of a scissor blade around its long axis, tuned during final assembly. Correct hineri ensures the cutting edges meet at the optimal angle along their entire length, preventing the blade from binding or releasing hair unevenly.

A skilled craftsperson devoted to mastering a trade. In the scissor world, shokunin carries deep respect. It implies years of apprenticeship and a personal commitment to quality that goes beyond simply doing a job.

The manufacturing model used in Seki City where different workshops specialize in different production stages like forging, grinding, heat treatment, and finishing. This is why multiple scissor brands can share the same component suppliers.

The general Japanese term for all edged cutting tools, including knives, scissors, and razors. When you see “hamono” on a product or storefront in Japan, it means the shop deals in bladed goods.

The final stage of scissor production, encompassing the last polish, quality check, and any decorative treatments. The quality of shiage is where you can feel the difference between a factory scissor and an artisan one.

Shaping steel by hammering or pressing it while hot. Forged scissors are generally considered superior to cast or stamped scissors because the process aligns the steel’s grain structure for improved strength.

Made by hand rather than by machine. Many premium Japanese scissors are described as tezukuri, meaning a craftsman guided each critical step. This is a meaningful distinction in an era of CNC production.

A custom engraving service where the stylist’s name is etched onto the blade. Common in Japan as a mark of professional pride and also a practical way to identify your tools in a busy salon.

A city in Hyogo Prefecture known as “the city of scissors” (hasami no machi). Ono’s scissor craft spans over 250 years and emphasizes high-precision hand-forging techniques.

The city in Gifu Prefecture that produces roughly 99% of Japan’s hairdressing scissors. Seki’s bladesmithing heritage stretches back over 780 years to the swordsmiths of the Kamakura period.

The art and process of sharpening scissor blades. In Japan, togi is considered a distinct craft with its own master practitioners (togishi). The final sharpening pass is what gives a scissor its cutting character.

The fine-tuning of the blade tips during final assembly, ensuring the two tips meet cleanly at the end of the cutting stroke. Poor sakizume causes tip drag or tip separation, both of which ruin precision work like point cutting and dry detailing.

The point where the two blades of a scissor meet during the cutting stroke. Premium Japanese scissors are designed with a precise shokuten that travels smoothly along the edges as the blades close, providing the signature “silk-slide” cutting feel.

A hardwood tool used by Japanese scissor craftsmen to adjust blade curvature by hand. The craftsman presses the blade against the tamegi and applies precisely calibrated force to tune the lengthwise bow (ogami) to within 0.03mm tolerance.

The practice of cutting on tissue paper or practice hair before using new scissors on clients. This breaks in the blade contact and lets you evaluate tension and alignment before real work.

The wire edge that forms on the back of a blade after sharpening, caused by steel displacement at the cutting edge. Skilled sharpeners remove the kaeriba through a final honing pass; a burr left in place will break off during cutting and leave a jagged edge.

Literally “cutting taste” — the subjective quality of how a scissor feels in use. Kireaji encompasses sharpness, smoothness, resistance, and the sound the blade makes. Japanese craftsmen treat kireaji as a distinct evaluative category that cannot be reduced to HRC hardness or edge geometry alone.

Sanitizing scissors between clients. Methods vary by regulation and include alcohol spray, UV cabinets, and chemical immersion. Proper disinfection protects clients without damaging the blade edge.

Cutting hair in its dry, natural state. This lets the stylist see exactly how the hair falls and behaves, making it easier to evaluate shape and movement during the cut.

The primary quality measure used by Japanese scissor craftsmen. Nagakire refers to how long a blade retains its cutting performance through daily professional use, combining initial sharpness, edge stability, and graceful degradation as the edge wears.

True left-handed scissors have reversed blade geometry so the upper blade is on the correct side for a left-hand grip. Using right-handed scissors in the left hand causes the blades to push hair rather than cut it.

Applying oil to the pivot area and blade surfaces. Regular oiling prevents corrosion, reduces friction, and extends the life of the scissors. Japanese craftsmen traditionally use camellia oil (tsubaki abura).

A carrying case or belt holster designed to hold multiple scissors, combs, and clips. Proper storage prevents blade damage from contact with other tools.

A fundamental barbering technique where the comb lifts the hair and the scissors cut along the top of the comb. Essential for fades, tapers, and short men’s cuts.

A technique where the scissors glide along the hair strand while slightly open, creating a tapered, feathered effect. Requires a sharp convex edge and a light touch.

The technique and tool category for removing bulk and reducing volume from the hair. Thinning scissors have toothed blades with a specific tooth count that determines the percentage of hair removed per cut.

The percentage of hair removed with each closing of a thinning scissor. A 20% thinning ratio removes roughly one fifth of the hair in the section. Higher ratios remove more hair per pass.

A licensed barber in Japan. Riyōshi hold a separate national license from hairstylists and are legally authorized to use straight razors on clients, which biyōshi are not.

A licensed hairstylist in Japan. The biyōshi license is a national certification that requires completing beauty school and passing a government exam. Japan distinguishes biyōshi (beauty) from riyōshi (barber) by law.

A beauty salon or hair salon in Japan. Japan has over 250,000 registered beauty salons, making it one of the most salon-dense countries in the world.

A sales representative who visits salons with sample cases. In Japan, dealers remain the dominant purchasing channel for professional scissors. They let stylists try before buying and provide ongoing service.

The actual sharpened cutting edge of the blade. A precise technical term used by German sharpeners and manufacturers to distinguish the edge from the blade body.

The concave inner blade surface found on most scissors. The German term is the equivalent of the Japanese urasuki.

Tiny teeth along the cutting edge that grip hair and prevent it from sliding forward during the cut. Common on German scissors and recommended for beginners or wet-cutting specialists.

The tension adjustment screw on a scissor. Stell means to adjust or set. This is the screw you turn to change how tight or loose the blades feel.

Ball bearings used in premium pivot systems. Kugel means ball, Lager means bearing. German manufacturers like Tondeo and e-kwip prominently feature ball-bearing screws in their premium lines.

A small rubber or plastic bumper between the handles that prevents the blades from over-opening. It also dampens noise and absorbs impact when the scissors close. Found on nearly all German-made professional shears.

The German term for the extreme ergonomic offset handle. Borrowed directly from the English word crane.

The small hook extending below the finger ring for the pinky to rest on. Finger means finger, Haken means hook.

The overall shape and ergonomic design of the scissor handle. German manufacturers categorize their scissors primarily by Griffform.

The German term for the offset handle design. As in Japanese scissors, offset is the most popular modern handle shape in German-made shears.

The general German term for screw. In scissor context, it refers to the pivot screw (Stellschraube for the adjustable version).

Cobalt as a steel alloying element. German manufacturers use cobalt in premium alloys for the same reasons as Japanese makers: improved hardness and edge retention.

The German term for Damascus steel. German manufacturers like Cerena and Tondeo produce Damascus scissors that combine Solingen craftsmanship with layered steel aesthetics.

Jaguar’s proprietary ice-hardening process. The steel is heated and then subjected to extreme cold treatment, producing improved hardness and edge stability. The name comes from Latin frigidus (cold) and durus (hard).

An allergic reaction to nickel in scissor metal. German research found that 11.4% of hairdressers are affected. Titanium coated scissors and low-nickel alloys like those from Joewell (under 0.6% nickel) are common solutions.

The German term for stainless steel. Literally “noble steel.” You will see this on nearly every German scissor specification sheet.

An alternative German term for hair scissors, emphasizing the cutting function. Haar means hair.

The general German word for scissors. You will encounter this root word in compound terms across German scissor catalogs and product descriptions.

The German city in North Rhine-Westphalia with over 800 years of bladesmithing heritage. “Made in Solingen” is a legally protected designation that carries the same weight in western markets as “Made in Seki” does in Japan.

A texturizing scissor with one smooth blade and one toothed blade. The German market maintains a clear vocabulary distinction between these and Effilierscheren.

Thinning scissors with double-toothed blades. Distinguished from the Modellierschere (texturizing scissors) which has only one toothed blade.

Literally “scissor knowledge.” Tondeo uses this as the name for their comprehensive educational hub covering scissor forms, blade technology, and tooth patterns. In general German usage, it refers to professional expertise about scissors.

Lubricating oil specifically formulated for scissor pivots. The German market produces several dedicated scissor oil products, and German maintenance guides emphasize daily oiling.

The German term for professional scissor sharpening. German sources strongly warn that self-sharpening destroys scissors in virtually all cases and that professional service is essential.

The German term for the sliding cut technique. Requires convex-edge scissors and produces a feathered, tapered result.

Creating texture and movement in hair using a single-toothed texturizing scissor (Modellierschere). The German market distinguishes clearly between effilieren (thinning) and texturieren (texturizing).

The German term for thinning hair with specialized scissors. Effilieren uses double-toothed blades (Effilierschere) to remove volume evenly throughout a section.

Tondeo’s proprietary ball-bearing screw system designed for ultra-smooth blade action. Representative of how Solingen brands develop and name their own pivot technologies.

Tondeo’s proprietary blade technology developed in Solingen. A branded manufacturing process that the company positions as their core technical advantage.

Electrically heated scissor blades that reach 110 to 170 degrees Celsius. The heat seals the hair cuticle as it cuts, which proponents claim reduces split ends. CARECUT is the leading brand in this category.

The standard German word for hairdresser. Germany has a formal apprenticeship system (Ausbildung) for hairdressers that includes training in scissor selection and care.

A hair salon. The German salon industry is large and well-regulated, with professional standards that include specific guidance on tool maintenance.

Convex-ground blades. French retailers position lames convexes as the premium blade geometry, often noting their Japanese origin.

The tension adjustment screw. Vis means screw, reglage means adjustment. French product listings always specify the screw type.

Ergonomic design. The French market places strong emphasis on ergonomics due to high awareness of TMS (troubles musculo-squelettiques), the French term for musculoskeletal disorders among hairdressers.

The finger rest or pinky hook. Literally “finger rest.” French product descriptions consistently list whether the repose-doigt is removable or fixed.

The pivot joint where the two blades connect. A technical French term used in professional descriptions and repair contexts.

The finger ring on a scissor handle. French ergonomic discussions focus on anneau size and shape as key comfort factors.

Any surface coating or treatment applied to the scissors. French product specifications use this term to describe everything from titanium to DLC (diamond-like carbon) finishes.

Cobalt-alloyed steel. French retailers highlight acier cobalt as a premium material, especially in Japanese-made scissors sold in the French market.

The French shorthand for Damascus steel (Acier Damas). French consumers associate Damas patterns with premium Japanese craftsmanship.

The French term for stainless steel. Acier means steel and inoxydable means stainless (literally “unable to oxidize”).

Titanium, used as a coating material on scissors. French product listings specify titane coatings as both a cosmetic upgrade and a practical solution for stylists with metal sensitivities.

Indicates the scissors were shaped by forging rather than stamping or casting. French retailers use this as a quality indicator, especially when describing Japanese-made shears.

The standard French term for professional hairdressing scissors. Coiffure means hairstyling.

The French word for scissors. Always plural in French because a scissor has two blades.

The preferred French term for thinning scissors. Literally “sculptor scissors,” reflecting the French view that thinning is a sculpting technique rather than simple volume removal.

Cutting hair while dry. French stylists use coupe sèche for final shaping and evaluation, similar to the Japanese dorai katto philosophy.

The Japanese clamshell sharpening technique as referenced in French technical literature. French sources specifically note that Japanese scissors require this method rather than the European convex grind.

The French approach to texturizing, which emphasizes sculpting the shape of the hair rather than just reducing volume. This philosophy influences how French brands design their thinning scissors.

Professional scissor sharpening. French brands like Takai maintain dedicated sharpening workshops (ateliers), with turnaround times of about one week from their Frejus facility.

The French term for the slide cutting technique where the scissors glide along the hair strand. The word literally means “slid” or “glided.”

The French verb for thinning hair. The related noun effilage describes the slide-cutting technique that originated in French hairdressing and was later adopted in Japan.

A French regulation requiring hairdressers to hold biocide certification for proper scissor and tool disinfection. Compliance has been required since 2026 and affects how salons purchase and maintain disinfection supplies.
