The ChefsChoice #450 sharpens all the way from blade tip to bolster or handle. It puts an excellent edge on a broad range of knives including kitchen cutlery and household knives as well as hunting knives, pocket and fish fillet knives. Compact, portable and lightweight, it requires no electricity, no lubrication and is ideal for use in the home, vacation cottage or trailer. It is equally at home on the kitchen counter or workbench, in a knapsack or in the tackle box.

How It Works:  In the first stage, medium diamond abrasives remove the old weak edge and simultaneously create a first bevel on both sides of the blade edge. In the

second stage, ultra-fine diamond abrasives create a second bevel on both sides, while polishing the edge to razor-sharpness. The result is a symmetrical, arch-shaped knife edge that is sharper and resists dulling longer.

Precision sharpening angle control is assured by easy-to-use conical roller guides. The built-in guides automatically establish the correct sharpening angles to produce the double-bevel edge. The user simply pulls the knife back and forth through each sharpening stage while holding the blade against the red roller guides. The rollers turn to confirm that the blade is properly positioned and the correct angle is being maintained. The same razor-sharp edge shape is created every time.  The Chef’sChoice®

Model 450 knife sharpener uses only 100% diamond abrasives, another feature critical to optimum sharpening. Using a proprietary process perfected by EdgeCraft, diamond abrasives are permanently bonded to steel sharpening pads. Since diamonds are the hardest and most efficient abrasive known, they will quickly sharpen any alloy. In addition, they do not ‘load up’ with sharpening dust.

Two different grits:  (medium in Stage 1 and ultra–fine in the Stage 2) enhance sharpening efficiency while carefully polishing the edge to incredible sharpness.
