Hello all, I haven't really carried a knife before, but the more I read, I think it would be a smart idea. What I'm looking for would be a good quality folder, for self-defense, and also general safety. Right now, I'm leaning towards an auto with a partially serrated blade...in the unlikely event I'd be involved in an accident or something, and would need to cut through something like a seatbelt. As for self defense, I'm not really sure what attributes are desirable. So far, I've sort of narrowed it down to the following choices, but I'm very open to suggestions. What do you all think of these: Microtech LUDT Auto http://www.bladehq.com/item--Microtech-LUDT-Automatic--6129 Protech Tactical Response 2.2 Auto http://www.bladehq.com/item--TR22-Protech-Tactical--3770 Protech Tactical Response 1.4 Tanto Auto http://www.bladehq.com/item--TR14S-Protech-Tactical--2722 or the Kershaw Emerson Commander Auto http://www.bladehq.com/item--Kershaw-Emerson-Commander--4095 All of them are roughly in the same price category, and all have somewhat similar features. I guess I'm wondering what blade shapes, size, general features you all think are important? Thanks, Brad Wanna kill these ads? We can help!
