The wood plate is a dedicated plate for skin-friendly crimp training. Made from high-strength walnut wood, the edges are rounded and tapered. This taper reduces stress on the skin and provides an exquisite grip. Improved holding power dramatically increases your limit grade. Train your fingers with the wood plate and push your limit grade.
