Store description excerpt
HollowGrind turns a radius of hollow (ROH) into the numbers that actually describe your skate edge: hollow depth and bite angle. Pick an ROH in inches or millimeters and your blade width — HollowGrind shows the hollow depth and the bite angle at the edge, with a cross-section view. Compare common ROH values side by side, or work in Flat Bottom V (FBV) mode. FEATURES • Hollow depth (sagitta) and bite angle from ROH and blade width • Inch-fraction ROH presets (3/8" to 1-1/2") and millimeters • Blade cross-section diagram • FBV (Flat Bottom V) mode • Side-by-side ROH comparison table • Save your blade profiles 100% offline. No ads. No tracking. No account. A one-time purchase.
