Use it when

The fit is obvious.

· Reach for the SHARPAL Diamond Block when the job is knife sharpening, chisel honing, and compact sharpening setup: 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 still need to remove stock, paint, filler, or machine marks; fine grit only polishes over problems it cannot fix.
· 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.
