Sword Blade
Sword Blade (剣刃 – Kenba)
Quick look
- Geometry: Reinforced spine (shinogi) stiffens the blade for even power transfer.1
- Glide profile: Works best with convex edges—smooth entry but purposeful bite.1,2
- Technique wheelhouse: Scissor-over-comb, blunt foundations, dense section control.1
- Care level: Medium-high; keep tension dialled and rely on convex specialists for service.1,3
Why it matters
Sword blades adapt katana-inspired ridges to hairdressing shears. The raised spine resists torsion, so long or heavy-duty shears stay aligned from heel to tip. When paired with a convex edge, you get crisp, decisive closes through coarse hair without the blade flex that can cause push-out on standard profiles.1,2
Blade pairing & edge compatibility
- Convex (Hamaguri-ba): Maximises clean entry while the ridge supplies the power.1,2
- Semi-convex alternatives: Offer a touch more durability for barbers who punish tools daily.3
Technique map
- High-speed scissor-over-comb or bulk removal on dense, resistant textures.1
- Blunt perimeter work where you want a decisive, pinch-free close.1
- Detailed tapering: use the reinforced tip for consistent bite at longer lengths.1
Usage notes
- Oil and set tension slightly firm before heavy sections; the ridge works best when the blades stay perfectly mated.1
- Close through the section in purposeful strokes—let the spine carry the load while you guide with the comb.1
- Follow with light point work if you need to soften weight lines after the power pass.1
Maintenance
- Preserve the convex grind and ridge geometry—request convex-capable sharpening only.2,3
- Wipe, dry, and oil after every service; store closed to protect the tip alignment.1
- Keep tension in the sweet spot: loose screws invite push-out, over-tight screws fatigue your hand.1
