Does anybody have any information on the durability of these two knives? I'm in the market for a new knife and these two are what I have narrowed my choices down to. I know the 275 has D2 steel, which to some is better than 154cm, but I'm worried I may not be able to re-sharpen it back to the way it was. Also I use a folding knife a lot, both in work and at home and I'm generally pretty hard on 'em. So, if you have any experience with either of these knives or have a recommendation for a better knife under 200 let me know. Thanks!!
