If you are looking for a simple way to keep your kitchen and tool shed in top condition, Paul Block’s American-made knife sharpener offers a versatile solution. In a recent video, Paul explains the unique design of his sharpener and how it can handle everything from standard chef’s knives to serrated blades and garden tools.
Unlike many sharpeners that grind metal away, the Block Knife Sharpener utilizes a patented “flex” design. Two butcher steels criss-cross and flex to follow the original cutting edge of your blade. This action hones the knife, putting the original bevel back into the blade rather than changing the angle or tearing metal off. This process takes the guesswork out of sharpening and ensures that your good knives last longer without being devalued.
One of the standout features of this sharpener is its versatility. Paul Block demonstrates that it can sharpen:
It is particularly effective on serrated knives. By rolling the blade in the middle of the rods, the sharpener vibrates and chatters through the teeth, hitting both the front and back of each tooth. Paul guarantees this method will make serrated knives “much sharper than brand new” without damaging the blade.
Using The sharpener is straightforward:
With roughly 32 colors available and a money-back guarantee, the Block Knife Sharpener is designed to be the last sharpener you need for every blade you own.
