Enter the width of the bevel (mm) and the length of the side of the bevel (mm) into the Knife Grind Angle Calculator. The calculator will evaluate the Knife Grind Angle.

## Knife Grind Angle Formula

The following two example problems outline the steps and information needed to calculate the Knife Grind Angle.

KGA = SIN^-1(W/L) /2

Variables:

- KFA is the Knife Grind Angle (degrees)
- W is the width of the bevel (mm)
- L is the length of the side of the bevel (mm)

To calculate the knife grind angle, take the inverse sin of the width of the bevel over the light of the side of the bevel, then divide by 2.

## How to Calculate Knife Grind Angle?

The following steps outline how to calculate the Knife Grind Angle.

- First, determine the width of the bevel (mm).
- Next, determine the length of the side of the bevel (mm).
- Next, gather the formula from above = KGA = SIN^-1(W/L) /2.
- Finally, calculate the Knife Grind Angle.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

width of the bevel (mm) = 2

length of the side of the bevel (mm) = 3

KGA = SIN^-1(W/L) /2** **= ?
