Mine has taken a heck of a beating. They are fantastic knifes and cost next to nothing. I strongly recommend them for EDC. I carry one as my utility blade and have no complaints.
They have a thick profile relative to other knives in the category, but a spyderco Delica will run you 6 times the cost easily. If you plan to abuse a knife, this one is strong enough to take it and maintain a pretty good edge. The carabiner is a fine bottle opener, and the OHO factor is awesome. Pocket clip keeps it in place really well and it doesn't open on accident. Can't really ask for much more than that from a folder!
