The Best Powder Steel Shears
Powder metallurgy steel is not a single grade but a production method. Molten metal is atomized into fine particles, cooled rapidly, and sintered under high pressure. The result is a finer, more uniform carbide structure than conventionally cast steel can produce — which means higher alloying is possible without the large carbide clumps that make conventional steel brittle. The practical payoff is greater hardness (most powder steel shears run 63 HRC and above) and edge retention that outlasts standard cobalt and VG-10 by a measurable margin.
What are the best powder steel scissors for hairdressers?
Powder steel shears sit at the performance end of the price range because the production method costs more to execute correctly. Toginon's Marine Shark, around $520, uses G Super cobalt powder steel in a 6.0 to 6.8 inch barber build. The Toki SG2 Series, around $550, uses Takefu's Super Gold 2 — a well-documented powder steel grade with vanadium and cobalt additions. Joewell's Supreme SPM, around $552, is Tokosha's powder metal alloy pair with a convex edge and offset handle. The Toginon Fuma FF, around $540, is a compact short-blade build in the same G Super powder family. Saki's Elite Powder, around $625, is the powder steel flagship from a specialist shear brand.
Powder metallurgy steel requires sharpeners with experience in the grade — conventional sharpening equipment can round the edge rather than refine it. Every pick below documents its steel type on the product page; before buying, confirm your sharpening service works with powder steel. Edge intervals are longer than standard cobalt, but when the edge does go, the regrind requires the right equipment.

What the production method changes
Standard stainless steels — including VG-10, 440C, and standard cobalt alloys — are produced by melting and casting. The cooling rate of a cast billet determines how carbide particles form and distribute. Slower cooling allows carbides to cluster into larger formations; larger formations reduce toughness and create weak points in the edge.
Powder metallurgy sidesteps this. The metal is atomized into fine droplets that freeze almost instantly, locking each particle at a uniform composition before they are sintered together under pressure. The resulting grain structure is finer and more consistent than casting can produce. That uniformity allows higher alloying — more vanadium, more cobalt — without the brittleness that large carbide clumps bring. The practical result is hardness above 63 HRC with workable toughness.
For cutting shears, this translates to one measurable advantage: edge retention. Powder steel shears hold a working edge longer than standard cobalt or VG-10 pairs at equivalent use levels. That advantage matters most in high-volume environments where a pair takes three to five full cuts per hour across a full working day.
The five picks
1. TOGINON Marine Shark (guide price around $520). Toginon’s G Super cobalt powder steel in a 6.0 and 6.8 inch barber build. G Super is Toginon’s proprietary powder cobalt grade, developed for the Marine Shark and the brand’s upper range. The longer blade lengths are suited to over-comb and channel work as well as general cutting on wider sections. SCISSOR STORY carries the Marine Shark in the Korean and international market.
2. Toki SG2 Series (around $550). Takefu’s Super Gold 2 (SG2) in a premium pair from Toki. SG2 is one of the most documented powder steel grades in the scissor market — the same Takefu mill that produces VG-10 makes SG2 through a powder metallurgy process at a higher hardness and finer carbide distribution. The Toki SG2 Series is available through specialist shear retailers including Shear Integrity.
3. Joewell Supreme SPM (around $552). Tokosha’s powder metal alloy — documented as SPM (Sintered Powder Metal) — in Joewell’s flagship offset pair. The product page explains the sintering process in its FAQ and specifically recommends working with a sharpener experienced in powder metal steel. Joewell’s Tokyo production has run since 1917, and the SPM is the premium grade in their range above the standard Supreme Stainless and CBA-1 cobalt lines.
4. TOGINON Fuma FF (around $540). A compact short-blade build from Toginon in G Super powder steel — the same proprietary cobalt powder grade as the Marine Shark, in a tighter blade profile suited to detail work, point cutting, and salon finishing. Available in Cobalt XX, Cobalt Special, and G Super grades; the G Super variant is the powder steel option. Sold through SCISSOR STORY.
5. Saki Elite Powder (around $625). The powder steel flagship from Saki Shears, in the Elite designation that marks the top tier of Saki’s catalogue. Saki documents this pair as its most capable cutting shear; the powder steel grade and the 6.25 inch build are the specification features on the product page. Available directly through sakishears.com.
How we chose
Each pick documents a powder metallurgy steel grade on its product page — SG2, G Super cobalt, Powder Metal Alloy (SPM), or “powder steel.” No picks here are based on marketing use of the word “powder” without a documented grade. Guide prices move; confirm current figures before buying, and confirm your sharpening access before committing to a powder grade.
The next step up
Powder steel is the last documented step before hand-forged custom steels and proprietary ultra-premium alloys. The premium shears roundup covers the pairs above $800, many of which use powder or proprietary cobalt grades at the top end of the ScissorPedia catalogue.
Frequently Asked Questions
Conventional steel is cast molten and solidified slowly, which allows carbide particles to cluster into larger formations. Powder metallurgy (PM) steel is atomized into particles first, cooled fast so each particle locks a uniform composition, then sintered under high pressure into a solid form. The finer carbide distribution means higher alloying elements can be added without causing brittleness from large carbide clumps — which enables higher hardness ratings and better wear resistance than conventional casting allows at the same alloy level.
Yes. The higher hardness (typically 63 HRC and above) and the finer grain structure mean conventional abrasive equipment struggles to set a new edge rather than just polish the existing one. Joewell’s Supreme SPM product page specifically recommends a sharpener experienced with Japanese convex edges and powder metal steel. If your current sharpener does not work with powder steel grades, the investment in the scissor is largely wasted when the edge needs refreshing.
VG-10 and standard cobalt alloys typically run 60 to 62 HRC. Most powder steel grades used in scissors — SG2, G Super cobalt, powder metal alloy — run 63 HRC and above. The practical difference is a longer edge interval: a powder steel pair that gets the same daily use as a VG-10 pair will typically go longer between sharpenings. The difference is most noticeable in high-volume salons where a scissor does three to five full cuts per hour. For lower-volume use, the difference is real but the cost premium may not justify it.
SG2, also called Super Gold 2 or R2, is Takefu Special Steel’s powder metallurgy grade. It is made by the same Japanese manufacturer as VG-10, using a powder metallurgy process that produces a finer carbide structure than the conventionally cast VG-10. SG2 carries vanadium and cobalt additions and typically rates 63 to 65 HRC in scissor applications. Takefu markets it as the step above VG-10 in its professional cutting steel line.
