Mini Brass Keychain Utility Knife - Replaceable Blades -Quick Change Folding Pocket Fine Edge Knife - Durable, Ingenious and Compact (Brass Knife)

I got this as a gift. I work in a place where we use xacto knives frequently but often times I am at a bench where the knife is missing. It is so handy to pull this little guy out and not wasteful time looking around for another knife. Blades are razor sharp and have a nice flex to them. Blade retracts into the body with no issues and I have not had it come out on it's own (granted this knife is kept in my lab coat pocket rather than my pants pocket). It is compact but I have not had any issues holding onto it. If I need to use a knife all day (we sometimes are cutting for hours on end) I will go a get a full sized knife, but for quick trims this is the perfect tool.

It’s inexpensive. It’s TINY. The problem is, that it doesn’t have much (or any) retention to hold the blade back. I’ve poked myself at least 5-6 times in the last two weeks. I’m retiring it before I cut myself worse.

So tiny you can hardly see it in you're hand .don't put this on you're keys .it doesn't lock closed. And it's way more useful and fun to fidget with just add some thin paracord or leather for a lanyard and keep it in you're pocket .you'll use it more often then you think . the brass construction is bullet proof and age's beautifully. Awesome product .one of my favourite knives and I have a lot.
