Hi BurrMan

Thank you for the precise explanation. Now I can sharpen the blades.
And nice render too with nice textures.

Thanks, it's nice to contribute.

I stumbled across this to work specific on this part, though trying to think how Michael would do it I thought he might suggest cutting it with a "swept surface" or a "sheet" if you will. This might be more practical for all and various situations. I'm going to try this also to see if what I'm thinking works.

Talk to you later,
Burr

Hi Apophis - very good result! Your render turned out very nice too, great looking metal texturing there.

How that is really a nice looking knife. Indeed a very good looking texture for the metal.
