I have the VG-10 version, and it has been my EDC for about 6 weeks now. I have had no trouble with it at all, and it is extremely smooth in operation. The linerlock appears to hold up quite well, and the upgrades it recieved from Spyderco when it got the VG-10 should only help in that dept. It is one of my favorite knives, but it is a little dressy for what I like to carry. Works great at school though, noone seems to complain about it.
