DupliSkate skate sharpening machines are used extensively by the largest sporting goods retailers in the world, as well as pro shops and arenas in over 30 countries. The Patent Pending NTPC (No Touch Precision Clamping) system ensures even edges with no adjustment regardless of blade width.
The precise depth of a blade's hollow and edge balance is measured using a tool called the hollow depth indicator (HDI). The indications of the HDI completely removes the skate grinding guesswork. Sani Sport of Wisconsin uses HDI on all skates to ensure edge balance and accurate hollow depth.
