The two photos with teeth are the same knife.

I liken this14 grind to a model 1 with teeth. I believe that the spearpoint grind of the 18 was used on the 14 for continuity more than any other reason. The 18 and 14 with teeth have the same blade forging, so it would make sense.

I think the 14's that maintain that 14 grind but with teeth are/were just a thing someone did in the shop maybe just to see how it would work. I dunno.

I have a picture, actually two of another I will post. Perhaps you can put them together jack into one photo.

I have no doubt the brown micarta 15 had the teeth added after the knife left the shop. No way it would have got out like that. Same guy did the teeth for 40+ years IIRC. You can still see the original grind as not been changed.
