Mine might be better than average, but I've never seen someone else's review say anything that really contradicts my feelings about it. It's smooth, like the lockbar is extremely well tuned and the pivot is killer for a Kizer, and I think if the design speaks to you this is one of the models that might be worth modifying.
If I were in a better place financially I would without a doubt send it to someone to mill out the internals and then to BladesWeLove. But I can't go buying hundreds of dollars in mods to simply lighten a knife that carries well enough in most pants, so I just carry it with jeans or what have you.
I'm stacking up Kizers too, they're hard to sell because they're so decent and the resale isn't very high, so I end up just keeping them all.
