We know that Work Sharp Sharpeners can sharpen a knife quickly. What about other EDC items, like your credit card? Gear Junkie recently tested out the Ken Onion Edition Knife & Tool Sharpener on both a butter knife and a credit card. Within five minutes, both items were slicing through plump tomatoes.
Take a look at this successful experiment! Now you can turn your credit card into a multi-purpose tool with Work Sharp.
