Lansky’s Deluxe Controlled-Angle Sharpening System allows even the most amateur users to sharpen knives quickly and efficiently. Sharpening a knife with a traditional stone can be difficult because holding the blade at the wrong, or an erratic angle does not allow for the blade’s bevel to be consistent. With this system, the angle guesswork is removed and the choice of hone grit is simple. Lansky advertises their system to make “Knife Sharpening as easy as 1,2,3!” and it really is.
