I don't know about this 31... I thought I loved it. Its hard not to love a brand new sebenza. But as I use it and carry it, there are a couple things that annoy me on a daily basis. 1- its hard to ignore the lock rock, and I'm constantly missing the "bank vault" lockup of the 21. 2- The clip. During certain grips, the clip slides off the frame and onto the lock bar while I'm using it and it drives me nuts because I can't help but stop cutting whatever I'm cutting, reposition the clip back to where it should be, and then continue cutting while consciously trying to grip it in such a way that I won't knock the clip out of position again which just interferes with my cutting. If it were up to me, the only changes that would have been made to the 31 would have been the removing of the locating hole and an upgrade in the steel. That's it. Debating selling this and looking for a 21. Anyone else feel the same way?
