Sorry for the nube question but what the heck does "manual" folder mean? I'm a huge fan of fixed blades. I only have two folders right now. I have a geber gator and a SOG flash II. I had a CRKT M16-SFG loved that. I have no idea where it went. I'm thinking about getting another one. I'm also looking at the spyderco endura and the cold steel recon 1. However manual folder keeps poping up. What does that mean?
