Tired of trying to guess what size of bearings you need? Well then this is your answer, and the end to your frustration. Not only does it save me time, it saves me money from not guessing what bearings I need and avoiding a purchase of the wrong size. Order one! You won't be disappointed, It's small and thin enough to keep securely in my wallet and whenever I need it, its available at hand. Awesome little piece here! Hats off to skiff blades for such an incredible high quality product.

These cheat sheets are a fantastic addition to any knife maintenance kit! I use mine all the time to quickly check bearing sizes, especially when I’m on the go. They’re incredibly easy to use, and their compact size means you can keep one just about anywhere. Plus, the purple is an absolutely beautiful shade!
