I only get a new pocket knife every few years when i wear out the old one. 'just not a collector I guess. One of the best knives I have ever had though was a Schrade single blade trapper with the brass"liner lock" No. 140 I think? I wore the blade out in about a year and a half sharpening it almost every day. At the time I was working in a big Dept. store and cutting MILES and MILES of corrugated cardboard every day, which is very abrasive. But with a little daily touch up and steeling the knife stayed card board whizzin sharp. I loved to pull it out and zip around a huge packing carton in front of a customer, zooooeeeeep!sheeples eyes would bug out. A great knife and a great design. I'd like to see it just a bit bigger.
