2Pack Mini Utility Knife Box Cutter, Compact Retractable Package Letter Opener, Small Pocket Knives EDC Cutting Tool Black and Orange, Gifts for Women Girls Men

The blade retention is a bit sub par. I've binned these as the blade drops out a bit and the sharp point stabs me in the knee whilst driving or in the leg when in my pocket. Don't bother buying unless you like to be randomly snapped out of your thoughts or task with a sharp pain.

Honestly this is an AMAZING product it’s comes in very very handy since I keep it on as a keychain.

Can’t tell you just how many times I’ve already used this after adding it to my keychain!! Opening packages, cutting the tape off of boxes at work, and really anything else that may require a quick sharp blade! Loved it! The only gripe I have is the locking mechanism. There’s been a few times where the blade has been open in my pocket without me knowing. Luckily I have yet to cut myself cause of it, but it did tear a small hole in my jean pockets at one point.

no locking mechanism. the blade just slides back in with barely any pressure.. I'd have an easier time opening a box with a dull key than this joke of a product. completely useless. returned it after first use.

It's super teeny, I use this at work several times a day, I already have small hands so it works perfectly. Was pretty dull so it needed a little bit of sharpening. If I've poked myself with it it's mostly user error not fully putting the blade away.
