I think I'll be issued the M9 bayonet. It won't be a folder, but when I get another one I think I will get a Spyderco - I have heard a lot of great things about them. And despite the pain it is to sharpen, I have been fond of the serrated combo blades. Or like the Charge where it has both I use the serrated blades on stuff that needs more than a straightedge and less than a saw - like rope or ripstop fabric. Oh, have you used the ones that aren't springloaded, but like slide out instead of flipping open? How do they compare such as durability and safety?
