Thinking about making a Three point tool: Question

Barry Irby
>I have a piece of 1/4" drill rod and was thinking of making a three point tool or point tool.

Is 1/4" a good size?

How long should the shaft be?

If I grind it on my eight inch grinder it will end up slightly hollow ground. Does that matter?

I am going to use a hex plumbing fitting for a feral and let that establish the angles for the facets. How critical is the "other" angle that establishes the "length" of the facets?
