The single most common error with a square point on cloth and thin sheet is holding the blade too steep, which makes the edge push the material ahead of the corner instead of cutting it. Lay the blade down; slice, don't chop.
02
Use the give
The .065" gauge has a little flex — enough to track a gentle curve and to get under a ply. Work with that flex on contours and lifts; if you need the blade to ignore the material and hold a dead-straight heavy line, that is the .083" 60450's job, not this one.
03
Tension the material
Cloth, webbing, and batting cut clean only under tension; slack material folds around the edge. Stretch or clamp the work before the stroke.
04
Maintain the edge on a stone
This is high-carbon cutlery steel and a maintained knife — hone it keen, strop it, and it will slice cloth for years; let it dull and it will start to drag and pull weave. Wipe dry after any damp work; carbon steel rusts where stainless would shrug.
Asked at the counter
BUYER QUESTIONS ANSWERED BEFORE THE CART, NOT AFTER THE RETURN
What's the difference between this and the 60450?
Blade thickness. .065" here (lively, follows the work) vs .083" there (stiff, for rubber and belting). Everything else is identical.
Best knife for cutting upholstery fabric?
This one at 4", or the 60570 at 5" for longer cuts.
Can I splice a belt with it?
It's the ply-lifting knife on a splice; use the 60450 to cut the cover.
Will it cut foam?
It can, but the hollow-ground 60180 cuts foam cleaner without wedging.
Does it need sharpening?
Yes — it's a maintained high-carbon knife. Hone it and wipe it dry after damp work.
