I'm looking for a good quality folder for EDC. Its going to see significant use and abuse on a daily basis, so I'd like something thats tough and can hold an edge well. Must be quick and easy to open with one hand. Looking to spend up to $150 on it I was thinking something like this maybe http://www.knifecenter.com/kc_new/store_detail.html?s=BM580SBK Or should i just get myself a griptilian and be done with it? Other suggestions?
