Been on a spending spree, buying up a bunch of knives to determine what works best for me. So far, this one is ahead of the pack:
Spyderco Gayle Bradley Folder #2
The gb2 is a great knife, (I sure love me some M4) but the lock is very difficult to unlock. If that’s not a problem it’s really a great knife, although I like the gb1 better.
Edited to add: you should also consider the stretch 2, pm2, and manix 2. Those last two are popular for a reason. The pm2 is my favorite out of those, but I like the blade of the stretch better.
