The point of a 5" blade is the continuous stroke — pull the whole edge through the material rather than sawing with the middle few inches. A long clean draw leaves a better edge on cloth and canvas than many short ones.
02
Low angle on textiles
Cloth and webbing cut only when the blade lies down and slices; held steep, the edge shoves the weave ahead of it. This is the difference between a clean cut and a fray.
03
Tension is everything
Canvas, cover cloth, and webbing must be stretched flat and held; slack material folds around the edge and cuts ragged. Weight the straightedge, clamp the panel, tension the strap.
04
Maintain the edge
High-carbon cutlery steel, honed on a stone and stropped, holds a slicing edge that shears weave cleanly; a dull square point drags and pulls threads. Wipe the blade dry after any damp work — carbon steel rusts where stainless would not.

BUYER QUESTIONS ANSWERED BEFORE THE CART, NOT AFTER THE RETURN
4" or 5" — which square point do I want?
5" (this one) for long cuts and wide material; 4" (60090) for shaped, close work.
Why a knife instead of shears for canvas?
Heavy canvas and duck distort under scissors; a long blade drawn on a straightedge cuts them clean.
