For my whole life, I carried around a blade for EDC, but none were really name-brand stuff until the last few years. My first real EDC was a Kershaw Tone and I -still- use it. It's a real beater. Strong knife, no blade play, and I've used it for batoning stuff up to a few inches thick. Best thing, I only paid like $30 bucks for the knife and if I'm not mistaken it has a lifetime warranty. You may not like this, but it's an assisted opening knife. I love it, and if you want to get a $30 knife that can take a beating, I'd say atleast try the Kershaw Tone out. I'm sure other people are going to suggest Spyderco's and whatnot, but I'm going to be an oddball and throw the Kershaw as an idea for you.
