Hidden Knife - 5.5" Kubaton - Small Black Secret Knife - Japanese Utility - Sharp Concealed Knives - Letter and Envelope Opener - Self Defense Pocket Knife for Men and Women - Best Gift Idea 130129

It's cool I thought it was more like a switchblade then having to unscrew it and flip it around and screw it back in so definitely not for defense more for I use it to open mail and boxes. It's a cool conversation piece tho

I am happy with the style and product, very good quality! However it takes a good minute to unscrew the knife then screw it back in which is a bit unrealistic for a self defense tool

I like how there is a lot of threading so it takes a bit to assemble, but overall it'll make it stronger. Also a keychain disables the blade until you take it off like a safety kinda. So that's kinda weird they put a hole there and the other side. It's got a good hand feel too.

It looks nice but it's not what I need.

The only thing I would say is you have to unscrew the blade to take it out and screw it again to put it on- not ideal in emergency situations. Takes about 25-40 seconds to do both.

The knife has a nice design, and does work on a keychain if desired.However, the blade screws in/out through the same hole. It wouldn't be good in carrying around for purposes other having it as a slower version of a pocket knife. It takes a little bit of time to screw out, then screw back in.

I didn’t even remember ordering this knife. So when it came with other knifes I did t know what it was untill I looked at my account.Very Nice! Yes, buy one.

Very sharp, but, you have to unscrew it to take out the blade, so nah! I had to return it.
