I have the offset, zt300 & both green & blue bumps.i think the bumps are the fanciest,very nicely machined & two toned anodized handles, nice satin blades & framelock.i think its the better for edc of the three. the studlock of the offset isnt as easy to close one handed,& when unlocking it, the blade can jump back slightly towards the closed position. this happened to me when i first got it,& it cut me at the spot where both blade grind profiles meet at the center of the blade.the pocket clip is huge,too, theres lots of risk scratching it up, & it can be seen much easier than the zt or bump. the zt is cool, but wide & heavy.real solid frame lock.huge & wide blade.all have 1st rate fit & finish.they are all real well made & unique,but the bumps seem to be the most practical to carry because of its slightly slimmer profile.
