The Hollow Grind Height Chart is a valuable quick reference guide to assist knifemakers in determining the appropriate grind height for their hollow ground blades.

The calculations assume a final edge thickness of 0.4mm.

Understanding the Formula:

The chart uses a mathematical formula to determine the grind height. The formula is as follows:

Formula: h = √((d/2)^2 - ((d/2) - ((t - e)/2))^2)

"d" = Wheel Diameter
"t" = Material Thickness
"e" = Edge Thickness
"h" = Grind Height
