Heh, Strider's not going to answer are they? well, at least strider's are tough so contacting them shouldnt happen to often.
Something important about me, i think i aught to have mentioned earlier, is i'm a fiddler. (no jokes

).
I've always had to do something with my hands. right now i've got my sebenza in front of me, and the amount i've fiddled with it, you can bet it's just about as smooth as it'll get. Other hobbies have been Yoyoing, playing card manipulation, and i've got almost every rubik's puzzle there is (and can solve them all muscle memory wise). I carried around a baliyo for a good 3 years, i never was out without it in my pocket.
I think that's the main reason i'm into the strider. the Umnumzaan, in my eyes, is the better example of craftmanship, and is likely far more than tough enough for my uses. But from all the youtube videos on the sng i've seen, it seems like more of a "fiddleable" knife.
I haven't handled the umnumzaan, so i can't say it won't be as "fiddleable" but, and it doesn't help that there are far more sng videos than umnumzaan videos. What do you think?
