those 2 are my favorites (i'm carrying almost everyday one of my 710 + a second knife)
Love the John W Smith SD you have. I have 2 of the SD-3's, both with the 4.5" blades. One is S30V, second is S35V. Black G-10 and Lightning Strike CF are the different handle materials. These folders are simply superb with fit/finish second to none. Also have Turpin, but not the model you show, as mine is a Repentance. What blade length SD is that?
it is 9 cm long blade (approx. 3 3/4" i think)
a great size for my edc use. i love this JWS !
