Shear Anatomy Fundamentals

Component overview

Part	Function	Tips
Tips	Precision cutting, detailing	Protect with blade guards; chips show first
Blades	Cutting surface shaped by edge type	Match blade geometry with Blade Types
Ride line	Interior polished strip that ensures smooth glide	Needs proper sharpening; avoid DIY fixes
Hollow grind	Scoop on the inside blade face that reduces friction	Look for clean, even polish
Spine	Adds rigidity; thicker spines support power cuts	Inspect for warping after drops
Pivot screw/dial	Holds blades together and sets tension	Adjust minimally; note original setting
Finger rings	House index/middle fingers; provide leverage	Use inserts to customize fit
Thumb ring	Controls opening motion	Should allow natural movement without overreaching
Finger rest (tang)	Stabilizes pinky and distributes weight	Tighten periodically

Diagnosing common issues

• Snagging at tips: Often caused by micro-chips or misaligned ride line—document and send to a pro sharpener.
• Clicking or catching: Pivot screw may be loose; check tension and inspect washer/bearing.
• Uneven closing pressure: Hollow grind could be uneven after poor sharpening; request a factory reset.
• Blade separation: Tension too loose or washers worn. Replace washers if grooves are visible.

Communicating with sharpeners

Provide:

• Shear make/model, steel type, and preferred edge finish
• Service history (dates, prior issues)
• Specific symptoms with photos if possible

Use a shared maintenance log so sharpeners can track adjustments.

Teaching clients

Use anatomy knowledge during consultations:

• Explain why convex edges feel smoother and require gentler handling.
• Show how proper storage prevents tip damage, reinforcing aftercare when clients invest in shears for home use.
