Performance-Enhancing Callus Care

Calluses are built in the work—but they’re maintained in the details.

The SandBar 8" Callus Kit is designed for athletes who live on the bar, the rings, the rope, or the rock. When calluses get too thick, too dry, or too jagged, they stop protecting you and start ripping—taking your grip, your confidence, and your training with them.

Unlike razors and harsh removers that strip calluses away completely, SandBar helps you keep the callus—just improved, smoothed, and working for you. The result: fewer tears, better grip, and hands that hold up through whatever you throw at them.

This is smart callus care for maximum performance.

Why It Works

Efficient + Precise

The 8" SandBar targets the thickest pressure points where calluses build from gripping—smoothing them down fast in seconds, not minutes.

Built for Performance

Maintaining the right callus thickness helps prevent rips, tears, and painful splits while preserving the protective layer your hands need.

Durable + Reliable

Solid aluminum construction engineered for real use—built to last 1 year+ with daily training.

FAQs

Every single day. Everytime you put friction and/or pressure on your skin, calluses build up. Your hands and feet have a high rate of skin cell turnover. The top layers dry out and build up faster than the rest of the body’s skin. Every rep, every step, every time you work hard with your hands and feet, you are creating build up. Manage your calluses by checking on them and filing them on a daily basis. Think of your SandBar as an industrial toothbrush for your calluses.

After a few uses, the abrasive surface will collect dead skin and can feel dull. Easy fix: wash it. Use the silicone scrubber that came with it. You can use it dry or with soap and water. Remember, SandBar is waterproof.

Abso-flippin-lutely. SandBar is made of aluminum, which doesn’t rust.
