(a) If your skate holder has cam handles: If your witness marks are not centered, you’re going to want to adjust the cam handle on the end of the blade that isn’t centered – either adjust them up or down depending on where your witness mark is currently located on your blade.

If the blade is too high, then you would be adjusting your cams down.
If the blade is too low, then you would be adjusting your cams up.

Once you have adjusted your cam, create two new witness marks on each end of your blade.

Continue to make these adjustments until your witness marks on both ends are centered on your blade.

Once centered, you’re going to make one swift and complete pass (maintaining even pressure)across the wheel. If your blade is straight, you will see the hollow grind centered all along the entire length of your blade. If you have achieved this, you are ready to sharpen your skates.

(b) IF YOUR SKATE HOLDER HAS THREE (3) DETENT (OR "CLICK") KNOBS:

If the witness mark is too high on one side, lower that side by turning the knob on at that side of the blade clockwise.
If the witness mark is too low on one side, raise that side by turning the knob on that sideof the blade counter-clockwise.
If the entire blade is too high, lower by turning the rear knob counter-clockwise.
If the entire blade is too low, raise by turning the rear knob clockwise.

Note – Our High Performance family of holders (i.e. SH6000, SH7000, SH8000 etc.) are designed to work with our BR100 & BR1000 skate gages. Two clicks of the detent knobs are relative to one graduation line shown on the gage.
