FAQ

Shouldn't athletes keep their calluses?

Functional calluses are essential — but overgrown, dry calluses lose elasticity. They crack during pivots, causing painful mat tears and creating open entry points for Staph and MRSA. The goal is smooth, tough skin — not thick, brittle skin.

How often should I use it?

For most combat athletes, once a week is enough to keep skin flexible without removing the protective layer you need for training. During heavy camp, every 5 days works well.

Should I use it on dry or damp feet?

Damp, softened skin after a shower gives the best results. It prevents irritation and allows for a smoother, more even finish without over-grinding.

How do I clean the grinding heads?

The grinding heads are detachable and washable. We recommend sanitizing with Rest Round™ HOCl Combat Spray after each use to maintain gym-grade hygiene and prevent cross-contamination.
