I have one and have had it for 3 years now blade lock up is sold, no wobble what so ever. The steel quality is meh, but will do its job, it's 1045. It opens fast, almost no effort needed at all, the blade alignment is not too great but that's not that big of a deal. I carry mine for defense simply because of how well it fits in my hand and how little effort is needed to open it, the steel isn't that great for daily jobs ( though you can manage fine with as a work knife) but the type of steel won't matter too much if it come down to defense salon as it handles well, wich it dose. I'm actually thinking of modding mine now to make it fit my hand better (new grips Maybey)
I have read some reviews on Amazon and some people seem to not have been as luck as me in getting one that opens well and has a nice lock up, so if your going to order one you might want to order a batch of 3 or so to make sure you get a good one, or just go for 1.
You should have no problem though, I don't use mine as much for a work knife anyone, because I have many high quality knives for that, I usually carry mine in my back pocket and have my work knife in my front pocket
!I will get this knife for fun , mod it little, and see how it holds up!Its super cheap.
