“Credit Card” Utility Knife


The CardSharp is an ultra-light and ultra-thin utility knife that fits comfortably into your wallet.

At 2.2mm thin, the 13-gram CardSharp transforms from a credit card sized sheet into a well-balanced knife with a sturdy handle.

The waterproof CardSharp features a nearly 3-inch long blade made from surgical steel, and the polypropylene handle is guaranteed to last a lifetime of unfolding and folding.

A clever locking mechanism prevents accidental cutting or blunting when the CardSharp is closed. Ensure you're always prepared with the CardSharp Credit Card Knife.

    Extremely cheap like similar ones. Blade is somewhat sharp. You get what you pay for…. Also do not advise keeping in your wallet, if called for juror duty or have business at and federal building or law enforcement where metal detectors are utilized, then you will have your wallet searched and item confiscated. Same thing with air ports. Just a FYI people.

    Good slim knife very sharp and well designed and I also like that the blade can be removed can make a good spear point if needed

    Not made by Ravencrest. Search Amazon for “credit card knife” and you’ll find s dozen different brands that are thIs exact knife. One has a 10 pack for $13.99. This and other knives sold by Ravencrest are made in China. These are branded Ravencrest but the knife arrives in a box marked “Made in China”, wasn’t expecting that. Not sure what’s going on here. The “About RCT” page talks about being in Mesa, AZ and that they “build and develop” there. I’m thinking that they actually just rebrand/resell goods from China there.

    A little flimsy but quite sharp and gets the job done in a pinch!
