I've almost always carried just a basic Case pocket knife for most days. I'm debating a Benchmade purchase, but not sure of which model. Don't really like serrated blade, and I want one that can also serve as a work knife. I work in a Chrysler parts department, so it needs to be capable of serving duty in there without quickly losing it's edge. I'd also like it to be a last ditch backup weapon, if that's possible as well. I've looked at two different sizes of the Griptillian, and tend to lean towards the larger. I'm not as knowledgable on these as I'd like to be, but I know I want a good, lifelong tool and a possible defensive weapon if both is possible out of one.
