Yeah, the Mini D/A OTF Automatic Knife Lighter is a pretty neat item, and it's one of the coolest novelty knives around! Not only does it have a double-edge blade with out-the-front automatic action, the built-in lighter is fully functional too. While the knife isn't going to do much more than open letters, it's a blast to have around for its entertainment factor and makes a great gift.

This one has a black finished body, and we have several other colors of the Mini OTF Lighter to choose from as well. One is never enough, and at this price you'll want to stock up!

It's fun

As a novelty it's awesome for sure. But with much fidget toys they don't last super long before parts break down. Still a very cool and fun while it lasts
So it's a bit of a fixer upper.

Alright, so other than the fact that the blade is about 1mm thick, looks like it was sharpened on a bench grinder, and the knife is terribly unreliable (read update below), it's actually pretty cool. I mean I paid $5 for the thing, so you can't expect too much out of it. At worst, I have a very reliable lighter that is sometimes a knife too.


So I took the knife apart, toyed with it for a while and figured out that the blade was actually firing too hard and was bouncing back before it had a chance to let the cam engage and lock up the blade. I took the spring out and stretched it just a bit so it wouldn't fire as hard and it works about 90% of the time now. Simple fix if you have the same problem. Even though I had to do some modifications to the knife to get it to work, I'm still pretty happy with my purchase. For $5, you can't beat it.
