Skate Hollow: ROH & FBV

Skate Hollow helps hockey and figure skaters pick the right radius of hollow (ROH) and understand exactly what it does to the blade. Pick a hollow and instantly see: - Bite (edge) angle — how much the edges grip the ice - Hollow depth — how deep the grind sits - FBV equivalent — the closest Blackstone flat-bottom-V feel (100/50, 90/1, and more) - Inch and millimeter, side by side FIND YOUR HOLLOW Not sure where to start? Enter your weight, skill level, position, and ice hardness to get a sensible starting-point range, based on widely used sharpening guides. It is a starting point, not a rule — your final choice is always yours and your sharpener's. SAVE YOUR SKATES Keep a list of your skates with their preferred hollow, FBV, and blade width, so you can tell any shop exactly what to grind. BUILT RIGHT - One time purchase. No subscription, no ads. - Works completely offline. Nothing leaves your device. - No account, no tracking, no permissions. The math is exact geometry; the recommendations and FBV feel-equivalents are guidance from published sharpening resources. Final sharpening and safety are the responsibility of the sharpener and skater.
