All wet stone grinders have 3 variables that need to be accounted for when setting the angle to grind a knife.

1. Grinding Wheel Diameter. (Automatically adjusts to current size.)

2. Universal Support Bar height. (No need to adjust Universal Support Bar height.)

3. Distance - Knife Jig Handle Stop to Knife Apex. (Adjust Handle Stop on knife jig to suit)

(Tormek KJ-45 and KJ-140 have fixed stops therefore not suitable. Most other jigs have an Adjustable Handle Stop)

WHAT makes this gauge different to the rest?

By adjusting only 1 variable (Distance - Knife Jig Handle Stop to Knife Apex) the set angle will be achieved even if the knife jig is not self centering. The grind will be slightly different on each side of the knife but the total angle will be accurate.
