5 Pack Safety Knife Package Box Opener Film Cutter with 2 Retractable Key Chain for Shrink Wrap, Stretch Wrap, Tape, and Plastic Straps

I was excited to use these safety knives, but they turned out to be a nightmare. On two separate knives, the plastic cracked near the blade, and both times, I ended up cutting my finger—one of them pretty badly. The blades are not secure at all, and they seem to snap or break easily.The keychain feature is the only thing that works, but it’s not worth risking injury just to have a tiny tool attached to your keys.

I work for one of the largest household product producers in the world. Safety knives are everywhere and part of my daily work life.The first day I was using them and they cut through plastic wrap beautifully. However, when I went and tried to cut corrugated boxes, the guard snapped and I received a laceration in my thumb. 5 stitches later and possibly tendon damage, take my warning: DO NOT BUY. EXTREMELY CHEAPFor reference, these went right through cut resistant level two safety gloves.

These safety knives are awesome, they are a great value as well. Come with the retractable lanyard so I don't drop my knife and lose it. The knife is so easy to use and makes opening boxes so easier, but they also work great on stripping the insulation off of armored cable.The performance is great and I will be getting more of these little gems.

I line how it has a clip so that’s a plus and earn the 3 stars . But it breaks at work and I actually cut myself twice after the safety broke off . So be careful everyone . And to the makers . Please add a more sturdy top so the blade safety guard don’t break off . You made the clip and the handle sturdy but the safety very flimsy . So please make the adjustments so nobody else will go through the blade cutting themselves

I've gone through 3 of these since I purchased them. While in use, the plastic tens to rip off...leaving a sharp blade exposed....thus needing to replace with a new one to avoid injury.

I really like the product so far, it's durability plus the belt clip and the connective cable makes it hard to lose or drop, I like the option of the clip or the belt loop, comes with five, this will probably last me a few years, I use it to cut plastic off the products in the trailer, so it's the perfect tool.

Great knife and really convenient

I absolutely love how I can cut a box open, drop the blade and it goes right back to my hip. The quality is cheap. I have broke three by cutting cardboard. If the company fixes the durability, I would buy more if they do not I will not buy more.
