I carry a small (3.75") Gerber liner lock to work. It's small enough that I can justify carrying it at work (pharmacy- opening boxes, etc). I just had the lock fail on me. The slightest tap on a hard surface and it folds right up. I would not trust a liner lock for my usual EDC knife. For that, I usually carry a Spyderco Endura and it's been okay. Still, it got me thinking. Other than the Endura, I have nothing to carry (outside pharmacy). I like the biggest knife I can get away with. I was thinking along the lines of a Cold Steel Recon 1 or AK-47. But still, there's no folder as strong as a fixed knife. Even if you break the handle off a fixed knife, you can wrap the tang with something and be back in business. The only benefit of folders is they are convenient and inconspicuous. I've seen some beautiful German-made, stag-handle small(ish) hunting knives (4.5-6" blade) on ebay. I'm thinking one of those should be my next investment. I have an ancient one with a broken tip my great uncle brought from Germany. Feels like "that's a knife" to me. Probably easier to pass off as a tool rather than weapon, compared to a small kabar or something "tactical" looking. Any experience EDCing one like that or suggestions for a very formidable folder?
