Save some $ and buy used. Like others who have responded, people don't tend to abuse the more expensive knives like they do with Spydercos, Gerbers, etc. (at least that is my experience!). The Sebenza feels good in the hand, has solid lockup, has a huge belly on the blade for smooth cutting, and is a joy to open and close. Really smooth! Used Sebbies can be had for around $300-350 used but in great condition. Just check the CPF marketplace every now and again, or even post a WTB in that section. Something is bound to come up!
