The knife doesn’t even work it’s like a kids toy


We are sorry to hear about the issues Mr Jaylin is experiencing, due to the concealed nature of this knife, it's much smaller in size than traditional knives, as described on our site. The blade itself is still very sharp and will work well in a pinch but since it is designed as a last resort it will not have some of the features of larger regular knives.

Credit Card Knife

The knife is flimsy and seems almost unsafe to use.


After reviewing Mr Brian's concerns with this item we reviewed other similar complaints and wanted to let customers know that while this knife may be less rigid than others this is the trade-off for having something paper-thin and concealed.

Handle is like a rubber band

Super sharp and well made. However, the handle simply bends if you put pressure on it. Fine for arts and crafts put you cannot put pressure on the unit
