Review on Utility Knife, BIBURY Upgraded Version Heavy Duty Box Cutter, Pocket Carpet Knife With 10 Replaceable SK5 Stainless Steel Blades, Belt Clip, Easy Release Button, Quick Change And Safety Lock-Red by Nick Brunner

I bought this one to replace my old box cutter that is nearly identical in form, but a different brand. That one was good but the lock mechanism ended up jamming, so it was unable to be closed.The BIBURY one is a great replacement. It weighs a little more than my old one, so it has more heft to it which I like. Other than that, nothing fancy. It locks in place when it opens and you push the button to unlock it so it can be folded closed.The blade comes out with a button push on the blade mechanism and replacement goes in easily. Seems sturdy and cuts fine. Mine came with a few replacement blades too which is nice.
