smaller and lighter than most box cutters I've used in the past (not really saying much there)Uses strange size for the blade so replacing it may require you to order from foreign countries.You have to unscrew the button in the middle and push it in order to engage the blade and slide it open. This part can become loose if you unscrew it enough and it can get lost.remember to take it out of your pants before washing it! (it will dismantle and you have to play needle in the haystack) otherwise it works fineIt's super compact but as mentioned above, the thumb screw is a problem. To adjust the blade you have to unscrew it which makes the ease of use untollerable. You can leave the thumb screw slightly loose, but then it will fall off.Was a very nice knife but the thumbscrew fell out and is lost after a couple days. Pretty much worthless now.Update: I constacted customer service about how I can get a replacement screw. They responded with one message and never followed through with letting me know how to get it. So customer service not to great.It falls apart in to pieces on its own I lost the blade ! I go to use it and it’s gone, vanished smhBeautiful in every way.Struggling to find blades because so many are “heavy” which is too thick for this.
