Which folder of yours has seen the heaviest use, and how has it responded?
For me it's a #10 Opinel. I've used it to chop and baton a lot when outdoors and it's seen a lot of acidic juices in the kitchen, especially for a carbon steel blade. I haven't really had any issues with it or the lock so far. A patina has formed from the food, the handle has gotten small dents in it from being whacked with a log and the blade has seen a couple of sharpening sessions, but otherwise it's still in great shape. I've been an advocate of these knives since the day I got my first, but I'm even a little surprised at how well they're holding up for me.
