Stabilizing feet give them a good grip on the surface that they are placed on so that the machine does not shake or move while in operation.

Two-Stage Sharpening

The 312 and 320 are two-stage sharpeners where the first stage is for old knives to be pre-sharpened and then sharpened. The second stage is used to hone and polish the knife blade in order to get the perfect sharpness. Fine diamond abrasives are used in the sharpening process.

Precision Guides

Both sharpeners have spring operated precision guides which help you to place the knife at the correct angle in order to optimize sharpening. In traditional sharpeners there is no control over the angle at which the knife is placed which results in poor sharpening of knives.

Knife Types & Abrasives

The 312 and 320 can sharpen a range of knives incl. straight edges as well as serrated blades. They can be used for pocket, sporting as well as household knives. The variety of knives that the sharpeners can be used on makes them popular with outdoor enthusiasts as well as Chef’s who need sharp blades for their kitchens. Furthermore, the 312 and 320 use diamond abrasives in the sharpening stages. This is the best method of knife-sharpening that ensures the highest degree of sharpness.

Easy Maintenance & Cleaning

Unlike other sharpeners you do not need to put oil or lubricate the sharpeners or the motors and bearings. Moreover, cleaning these machines is very easy. The metal shavings are collected inside due to magnetic action and only have to be emptied out by removing the tray. The cleaning itself can be done once a year. This also makes sure that microscopic pieces of metal do not fall into food items.


Edgecraft guarantees that the material used will never detemper knives that are used in these machines. This will keep your blades safe while being sharpened by these machines.
