Hollow depth affects "traction" or "bite". Deeper hollow will have more "bite" or "traction" than shallow hollow. Centering the hollow creates level edges and equal "bite" or "traction" on all sides of the skate blade. Off center grinding creates one high edge and one low edge. The low edge can not penetrate the ice properly and will result in unexpected release under pressure while the high edge will have excessive bite. Uneven edges are all too common and contribute to very poor performance.

HDI Instruction Steps

1. Place HDI on skate blade. Tighten knob gently clamping tool to blade. DO NOT over tighten!

2. Push gauge slide to the left until it stops. Gauge is directly on top of left gauge.

3. Turn face of gauge so dial points to zero. note the "+" and "-" on each side of zero.

4. Push gauge slide slowly to the right until it stops. Dial movement will indicate hollow depth and edge level. Note example below.

Center grinding or sharpening is somewhat difficult to achieve without the use of the HDI tool. The HDI provides both skate sharpener professional and skater with a fool proof method of measuring hollow depth and determining edge balance.
