✕DO NOT FORCE THE FIT
- Conveyor belting and heavy rubber splice work — .065" is stiff for leather but the belt trades run on the .083" full-size square points; the #5 is a leather-and-tack knife, not a belt knife.
- Sole-leather thinning — paring sole stock to thickness is the sole skiver's (55190) .072" shaving job; the #5 trims the assembled sole edge but does not skive dense sole hide.
- Fine detail and tight corners — the wide 7/8" blade is a trimming tool, not the narrow #2's corner knife.
- Starting a cut inside a panel — the square end refuses to pierce; that is the English shoe knife's (55500) forward-point capability.
- And it is not a pry bar: keep the committed force in the plane of the cut, not levering the edge.
