Doing some research on knives and came across opinel.  They have been making them since 1880, they float, carbon or stainless, what's not to like?  Under $20.

Surprised they haven't been mentioned here.  I had never heard of them.

Anyone have one?

I had one of the opinel carbon steel outdoor folding knives. I don't like the locking mechanism: you have to remember to engage it and if you don't you risk slicing your knuckles. Because it is carbon steel the blade sharpens nicely but is prone to rust. The blade was also somewhat fragile and I ended up breaking the tip, probably because I was abusing it. Overall I think they work fine as a knife to carry in your picnic basket but not as a general purpose pocketknife.

Eric, you might want to look at the mora knives if you haven't already   they're under $20 and get super sharp.  Sorry I missed you this weekend.

My mora and opinel knives arrived today.  Initial impressions?  The opinel is a handy design.  I like that it's light and sharp.  The locking mechanism is crude but rock solid.  I could see this as a handy every day carry pocket knife.  It's very ergonomic.  Much more elegant and light than a folding buck.

The mora is all business.  This is the knife I can see breaking down a pig or anything else unlucky enough to be in the way.
