Edge Lab

See what your edges see.

A cutting edge looks sharp to the eye long after it stops cutting well. Use the lab to see what weeks of use do to an edge under magnification, and why a proper sharpen is more than a quick grind.

Edge anatomy

Three edges, three jobs.

Each needs a different machine and a different hand. That's why we never send a convex scissor through a bevel jig.

BeforeAfter

Clipper blade

A flat-honed cutter running across a comb. Sharpness comes from two dead-flat faces meeting, not from an angled edge.

BeforeAfter

Bevel scissor

A flat angled bevel, often with micro-serrations to grip. Tough and forgiving, and the standard for grooming scissors.

BeforeAfter

Convex scissor

A curved, razor-fine edge for slide-cutting. The sharpest and the easiest to ruin. Hand-honed on stones only.

The burr

Why quick sharpening doesn't last.

Grinding pushes a thin wire of metal, the burr, over the edge. It feels sharp for a day, then folds over and the tool is blunter than before. Removing the burr properly takes fine honing and time.

Every Edgewise sharpen ends with burr removal and a test-cut, so the edge you get back is the edge that lasts.
