I'm torn between the ZT 0550 and Spyderco PM2 for EDC. I have carried the Spyderco Endura for the last 6 years. Though I've bought many other knives (Benchmade 9052, Sypderco Lum Tanto, Emerson Commander, Sog Trident, Kershaw Leek, Gerber Fairborn), I keep going back to the Endura for its slim profile and ease to carry. The purpose for this new knife is just to upgrade. I'm really interested in a frame lock knife and the ZT 0550 really seems like a good option. At this time $200 is the most I'm willing to spend. I would appreciate recommendations between these 2 knives or any other suggestions in this price range. I'm active duty army so always have my EDC on me.
