I'm genuinely suprised about this one. Not a a fast opener for me. Just because of the thumb stud placement makes it a bit hard. More of a show roller most of the time, but that's okay with me. Great lockup. No play in any direction at all. Like most metal handle knives, it's a bit slippery at hand. Very slicy blade with a good grind. Seems to be a good heat treatment too. Pocket clip is okay.
I don't think you can get a better or more reliable and sturdy pocket knife at this price range (less than 20€)
