Straight Blade
Straight Blade (直刃 – Jikiba / Chokuha)
Quick look
- Geometry: Minimal belly and a flat profile that tracks true lines.1
- Glide profile: Often paired with beveled or micro-serrated edges for secure bite.2
- Technique wheelhouse: Blunt lines, scissor-over-comb, foundational training work.1,2
- Care level: Moderate—keep tension firm and preserve any micro-serrations during service.2
Why it matters
Straight blades are the baseline geometry for professional shears. The flat presentation keeps hair from climbing the blade, so stylists can cut precise perimeters and run scissor-over-comb passes without drift. With a micro-serrated or beveled working edge, they deliver predictable grip—perfect for students or barbers who need stability more than slide-focused finesse.1,2
Blade pairing & edge compatibility
- Beveled / micro-serrated (most common): Locks hair in place for blunt and over-comb work with minimal slip.2
- Semi-convex: Softens entry while retaining enough grip for everyday cutting.2
- Convex: Used when you want straighter tracking but still need the silky glide of a convex edge.2
Technique map
- Blunt perimeter cuts on wet hair; the flat blade keeps lines crisp.1
- Scissor-over-comb in barbering—predictable resistance and control.1
- Training scenarios where stylists develop muscle memory before graduating to slide-oriented tools.1
Usage notes
- Maintain modest tension on the section; over-stretching will rebound and ruin straight lines.1
- Close decisively through the guide—micro-serrations prevent slippage on fine hair.2
- Cross-check frequently; the blade will faithfully reproduce whatever line you set.1
Maintenance
- Keep pivot tension slightly firm so hair doesn’t push at the heel.2
- If one blade is micro-serrated, request sharpening that preserves those teeth.2
- Wipe, dry, and oil daily along the hone line; store closed to protect the edges.2
