Good thread guys.
Here's a link to a vid Dave Canterbury did about selecting Knives. As he stresses, it's just his opinion, but I think it lays down a good foundation for looking at knives. I disagree with some of his criteria, but I think he gives you some good ideas for how evaluate what your preferences and priorities are when choosing knives.
