I've always thought the term "zero tolerance edge, or zero tolerance grind" meant an edge with no secondary bevel. A cannell grind, a rolled edge, or even a simple V grind would be examples. However, now I'm wondering if I simply invented the term, because when I use it people don't understand. Am I having a senior moment:)?

If it is a senior moment :) I think it can be associated with "Zero Tolerance", which I believe is a knife company..:D

You're right about the grind, and I know you're referring to a 'zero degree grind' , 'zero degree bevel' , 'zero degree edge' etc, but I really think your zero tolerance edge is way more marketable.. :D

take care,
 
Man oh man! And I'm cold stone sober too! haha, yes, zero degree edge sounds right.Thanks Guys

I never considered the term valid; zero bevel, zero degree grind or even zero thickness edge, doesn't have a defined meaning. You are measuring something, right; what is it thats being measured? You can't measure nothing and thats what an edge is. The edge itself is just a line, its whats behind the line that counts. So to me, it makes more seance to discuss the combined angle of the bevels, relative to the center line and whether the bevels were ground to infinity resulting in intersecting bevels with no secondary angle above the actual edge of the blade.

Infinity flat grind, I believe, might be a more relative term than zero edge, when discussing bevels and angles used in designing blades.

Okay,

I think 12345678910 was just having a little fun with me, but Fred, your'e response is awesome. Infinity flat grind, Wow! But, well...I, uhh, I'll think of something later.

Maybe a more accurate term would be: full-depth-flat-grind-with-no(zero)-secondary-edge-bevel....edge. ;) As long as people know what you're talking about, it's all good. In your case, I guess the whole reason we're having this discussion is that they didn't now what you were talking about :D in which case a picture is worth a thousand words.

Convex
Convex to zero (zero in this case meaning no edge bevel)
Full convex
