This compact titanium folding knife by Titaner is always sharp, very tiny, and very sturdy. And you’ll barely notice it in your pocket as it’s less than 2.5 inches long closed.
The body of the pocket knife is made from grade 5 titanium metal, is rust and corrosion proof, and utilizes #11 scalpel blades (like these). This means that you can use the little bugger to whittle or cut through just about anything, knowing that you can destroy the current blade and just replace it.
