How good are Sebenzas as EDC's? As good as it gets, IMHO. You're not going to find a better knife, ever. I've been carrying my small 21 for 10 months solid now, the longest I've carried the same knife for many, many years. It is as close to perfect as anything made by the hands of man can be. The titanium slabs will wear, but nowhere near as much as, say, a Spyderco steel handled knife. The bead blast finish on the corners will wear smooth, and look "brighter" than the rest of the knife. The center of the slabs will grow a bit darker. The most noticeable wear will be on the clip, as it is outside of your pocket and rubs on stuff as you move around. Titanium is highly abrasion resistant, so what you'll get is an accumulation of tiny, shallow scratches, that is just on the surface. I think my Seb looks better now than it did when I got it. It looks "broken in". At this rate of wear, it should last a good 50-100 years, maybe longer. I will certainly wear out before the knife will.
I've found the steel to be excellent. I have had to "sharpen" the knife exactly once in the past 10 months. That was because I cut through some ties holding a toy for my son in the package, and there was steel inside of the ties- which rolled the edge a tiny bit in a couple places. I steeled and sharpened it up, and it has been good to go. Every couple weeks I'll give the blade a couple of swipes on a strop loaded with medium, and then fine compound- and it stays nice and razor sharp. It's been exceptionally easy to maintain. At this rate of wear, the blade should last a good deal longer than I will. Some day, my son may be carrying this knife as he plays with his grandchildren, long after I am gone. This thing is built to last. :thumbup:
