Parabolic Curved Grind Line

[Rock]

I have a design I am working on with a couple of makers. One is a fixed blade and one is a folder.

The question has arisen;

What is the best way to create a parabolic curved grind line?

Any suggestions, tips, hints, or links to a tutorial would be greatly appreciated!

Thanks in advance!

Do you have access to a CNC?

Checking, Gabe. I believe the answer will be yes.

By parabolic curved grind line, you mean that the boundary between the flats and primary bevel is a parabola, or do you mean that the profile of the blade itself is a parabola (as opposed to flat ground, hollow ground, or convex)?

Gabe,

I think its hollow ground. I am not entirely sure why that maker referred to it this way. Without showing that new design, this other design of mine is very similar in that aspect.

Thanks,

Rock
