Customer Rating:
Summary: Light Duty Knife
Comment: This is a very light duty knife and the blade will come out if used for anything other than cutting open boxes. I picked up a couple for less than five bucks apiece, but I still don't think it was worth it. Spend a little extra on a better knife. It will be a lot safer and less frustrating!

Customer Rating:
Summary: Decent and affordable
Comment: Overall the knife is a decent product. It's durable and light weight.

The biggest problem is the quick change. It's easy to use, but it doesn't hold the blade very securely. Sometimes if the blade hangs up on something it pulls right out of the knife.

I recommend it for light use (opening boxes) and not for heavy duty use (cutting cardboard).
