They are extremely sharp and perfect when working with bare Metal Foil or when you need a blade that is sharper than the normal hobby knife blade. (4) Sharpest blades there is By: nscrfns (Killeen, TX) Sharper than hobby blades. They last longer because they're sharper. More flex than hobby blades so don't force them. (5)
