Pros: -A cool lighter that works neatly.
-The blade is pretty sharp and opens fast
-The whole system is quite disguised , no one will notice you are carrying a pen knife.
-It survived to a 1,50 m fall from a bike going at 60 km/h

Cons: -Don't expect to cut things with this knife, it is a lighter with a knife AS A TOY (I didn't expect more)
-The lighters body isn't made with finely shaped carbon steel ;)

Other Thoughts: Good toy , don't expect more

Bottomline: Buy it if you want to show off and mess arround ,if you want a knife , buy a knife.

Pros: -Its cheap
-Feels nice in my hand
-Good stable jet-flame
-VERY sharp knife
-knife pops in and out automatically, very fast
-nice weight

Cons: -build quality is crap.
-knife is stuck after you sliced something with it (had to jiggle to get it back)
-jet flame isn't green, but dark-red.
-came without gas (not a real con..)

Other Thoughts: It'd be nice if the knife was better mounted into the lighter. Also the cap of the lighter is a bit loose. But, for the price of it its worth it.

Bottomline: Just use the knife to show off, not to cut things. Well, you can but be sure to hold the blade, not the lighter ;-).
For this price its a reasonable product. At least the main function (the lighter) works just fine, after filling it.

Pros: Very cool automatic knife! The blade is quite sharp and with a flick of a switch it comes out vertically and it even pushes itself back in with the switch! It can slice through a bottle and definitly a person or even meat. The blade length is about 7cm?

Cons: The butane lighter came empty and i tried refilling it but no luck. im only interested in the knife anyway. The build quality is also VERRRRY cheap. My first few tries of making go in and out, the blade came out of place but you juts have to flick it in and out a few times and it goes back in place. I also cut the ground up a bit and the blade finally got jammed forever even after attempts to fix it so not very good quality but still very very sharp.

Other Thoughts:

Bottomline: I would get a few if I were you and it can be easily sold for a lot of bucks as it is a very cool looking toy or tool for some people. I say this is very cheap but also cheap quality but for the price it's awesome! since mine is jammed im going to still buy more. maybe in bulk.

Pros: It's cool... there's really nothing more to say. Torches are cool. Automatic knives are cool. It's both. It's cool...
The flame is red. The lighter is easy to fill and adjust. Mine needed to be turned up a lot before it worked.
The knife isn't very useful, but it's a great addition to a lighter. It would be good for opening soft packs.

Cons: The blade is almost worthless. It jiggles when it is open. It isn't sharp. It seems as though the mechanism will stop working after a few hundred uses. That's a shame because it is so much fun to play with I'll probably break it in no time at all.

Other Thoughts:

Bottomline: I was worried about legality, so I did some research before ordering this thing. In California it is NOT illegal to own. I'm no lawyer, so don't take my word for it. I wouldn't recommend carrying it. The actual sharpened part of the blade is less than 2 and a half inches, so it shouldn't be a problem, but California is California so just don't do it. It's just a fun toy.
