ok so heres a little review on the Umnumzaan. ive been carrying it for only a couple days now. first thing that i want to mention about it... the thumb stud is super comfy, way more than the Sebbie. the ergo's on the handle are great, fits the hand very nice. the engraving or etching in the Ti scales are actually very grippy. for me the Umnum is a little on the big side, i prefer the size of the small Sebbie. its a little heavier in the pocket too. i love the blade shape, perfect for edc. if the Sebbie wasnt for you, i would say if you have the chance, give the Umnumzaan a try.
