These are cheap, sharp, easy to maintain, and you don't feel too bad if they get lost. I lent my son my suitcase, with my previous no.8 in the inside pocket by accident and he made it through three airports before the TSA in Chicago confiscated it. Apart from the memories it held, it was no huge loss and i had it replaced the next day.
Opinels are the sliciest folders most people will ever have in their hand.
If you've got an Opinel and a Mora you're got your bases covered for, like, $30 USD. Both cheap, both well made, both very good knives and can be made razor sharp with improvised sharpeners like coffee mugs and river rocks and leather belts. The Mora has the heft for heavier work and the Opinel's thin blade stock is perfect for precise cutting.
don't get me wrong, I love my expensive, finely machined customs and midtechs and high end production knives for what they are. But there's something about excellent budget knives that you've just gotta love. That's what it's really about in terms of tools being put to work in the real world. Just about anyone can afford 'em, anyone can learn to sharpen them, and people aren't afraid to actually use them lest they damage an expensive purchase.
There was a really good budget knives sub over at the place not to be named. Hope we get something like that going over here.
