Use it when
The fit is obvious.
- · Reach for the EZLap Diamond Files when the job is serrated blade sharpening, carving tools, and detail filing: that is the fight it was built for.
- · Diamond is the only grain hard enough to boss stone, glass, and cured concrete around. Everything else just negotiates.
- · This is refinement territory. It flatters a surface that is already close; it will not rescue a rough one.
Skip it when
The job asks for something else.
- · Leave it if you are actually solving a different stage of the climb than the one this pick was chosen for.
- · Leave it if longevity and cut speed matter more than the price: cheap abrasive is cheap for reasons you feel on the tenth sheet.
- · Leave it if the work is edges, profiles, and tiny repairs: those are easier to control by hand.
Best for
Where it earns its keep.
- · serrated blade sharpening
- · carving tools
- · detail filing
- · field use
