Ive got both of the above knives and like them both a lot.
THe Yari was cheaper would be more utilitarian and is a little smaller in all dimensions.
I think it would be more concealable and would be an excellent defensive blade, a great utility blade, and a good choice for EDC.
It is my designated beater knife but so far I haven't done too much to it.
Cuts cheese well and does good food prep,
I like the sheath and it carries well in SOB or as a frequently carry it under belt in front of my hip when I may use it a lot.
For the money its a winner.
The Camillus seems a little more of a fighter to me. But its pretty damn cool as well. The Yari feels like its little brother in a way that the CQB2 doesn't quite fit.
