I'm a great fan of the Joker no74.
Small, cheap, inoffensive with a versatile blade that's easy to keep sharp.
What's not to like?
Yeah, I like the Jokers as well.
They look nice and take a really good edge.
BUT.
The spring is incredibly weak. I've had two of them and they've both been the same. They close and bite you very easily, which is even worse when you consider how sharp you can get them. My breaking point was when one closed on me and gave me a very nasty cut indeed.
Shame because they are good knives, I just wish the spring was a bit tougher or there was a reasonable way of adjusting them. But for that reason I wouldn't touch another one, however much I like them otherwise.
If all you're going to do is cut a bit of string or slice up a pepperami then they are great. But if you intend on doing any kind of carving or whittling with them (let alone 'heavy duty' then there's a very high chance indeed the blade will close on you. It's happened to me many times.
Here's one I like.
The British Army pocket knife. One of these:

The spring is tough, the blade is strong, and it takes a very good edge.
Yes, it's a bit brutish in appearance. But you can always add some scales to it, which is what I did with mine:
This is the knife I use about 99% of the time. It's tough and strong and a good price. It does all kind of whittling and carving projects (it's what I use) and other general camp tasks.
