When thinking about an EDC knife purchase, there are so many choices that it helps to evaluate them against some sort of criteria. The following video lists the seven main things to focus on when choosing an EDC knife.
The first general criteria is what are you going to be using the knife for. An EDC knife pretty much by definition is not your wilderness survival knife, so make sure you are realistic about how you are going to use it. It makes evaluating the knives you are considering that much easier.
The host of the video uses the Benchmade Osborne 940 as an example.
