I have seriously been contemplating getting a Strider SNG in the very near future... such an awesome knife from what I've read here. I've never owned a ti frame lock. Anyways, I was looking at the blade length .... is 3.5 in. the cutting edge length or the cutting edge plus choil. I'm into bigger folders (hence my millie, bm 710 & 800, Emerson commander, cs voyager ) I know this is a smaller blade than the others but I'm fine as long as 3.5 is the cutting edge. Do I need to get the SMF?
