I just purchased an Emerson Commander that I'm very impressed with. Great knife. However, I must brag a little on Spyderco. They take absolute care of their customers. Total customer satisfaction that's WAY above and beyond the call of duty. And they make great knives too!
In fact, they've really won me over with their stellar handling of a warranty issue. I will be buying Spydies from here on out.
Cheers.
