Why rubber abrasives belong between belts and hand sanding

  • Controlled detail work

    Belt grinders remove material fast. Sandpaper gives control, but it is slow around shoulders, plunge lines, guards, bolsters, and handle transitions.

  • Enough cut, enough give

    Cratex rubberized abrasives sit in the middle: enough cut to refine scratches and shape detail areas, enough give to avoid the harsh bite of a hard stone or aggressive belt.

  • Four grit levels

    Coarse, Medium, Fine, and Extra Fine let you step through scratch removal instead of jumping straight from aggressive work to polish.

  • Shapes that fit knife problems

    Wheels, points, sticks, and mandrels reach plunge lines, ricassos, choils, guards, and bolsters where flat tools struggle.
