Overview

The leather knife, often a Japanese skiving style, is the workhorse blade of hand leathercraft. It handles straight cuts along a steel ruler, freehand curves, and the thinning pass known as skiving. Most beginners start with a replaceable-blade model because it needs no sharpening, then move to a fixed high-carbon blade that holds a keener edge.

Use it to trim pattern pieces, split a strap to an even thickness, and shave the folded edges of a wallet before gluing. A sharp knife should slice leather with almost no downward pressure; if you have to push hard, the blade is dull or the leather is too thick for one pass. Change or strop the blade as soon as the cut starts to drag.

Choose a knife by blade geometry rather than brand. A shallow 30 degree bevel suits fine skiving, while a steeper 45 degree bevel survives heavier trimming. Look for a handle that keeps your wrist straight, and keep a strop and compound beside the bench so touching up takes seconds.

Safety

Hazard. The blade is razor sharp and can sever a finger; always cut away from your body and keep the off hand behind the blade path.

How to use it well

  • Strop the blade every few cuts to keep the edge keen and the line accurate.
  • Cut on a self-healing mat or a cutting board, never directly on a hard bench.
  • Make two light passes rather than one heavy pass through thick leather.
  • Store the knife in a sheath so the edge is not chipped in a drawer.
