Credit Card Size Folding Knife

The Cardsharp 2, designed by Iain Sinclair, is one of those tools you forget is in your wallet, until you are very glad it is. About the size of a credit card, it folds into a solid, usable knife that is ready whenever a small cutting job comes up, without carrying a bulky blade or multi tool.

Built for real world use, the Cardsharp 2 opens into a rigid, comfortable grip with a stainless steel blade sharp enough to handle everyday tasks. It easily cuts paper, rope, packaging, cord, fruit, and food prep while camping or traveling. The design locks together securely when opened, so it feels far more substantial than you would expect from something that stores flat in your wallet.

This is a practical tool for men who like to be prepared, whether that means hiking, fishing, camping, working in the garage, or just handling daily tasks where a knife comes in handy. Lightweight, discreet, and always with you, the Cardsharp 2 offers simple reliability without fuss, batteries, or moving parts that can fail.

For men who appreciate smart design and useful gear that earns its place, this wallet knife delivers capability without taking up space.
