FTR-14c, it looks to me like the edge is thinner on my 3v compared to my San Mai. It could be the taper throwing me off, but the 3v blade looks thinner at the edge. Hope this helps.
It looks like ColdSteel is taking advantage of 3vs toughness by thinning down the blade some. That is very encouraging, I already liked the San Mia version, the 3v looks awesome.
For those who have both, is there any difference in thickness at or behind the edge? That's where it counts!
