The grey sharpener is the one built around separate slots. Rather than sending five angles through a single pair of wheels, it gives 15, 18, 20, 22 and 24 degrees a dedicated coarse channel each. The fine slot works differently again: a spring lets the wheels close onto whatever bevel the blade already has, so a touch-up does not fight the grind the knife came with.

Anatomy of the tool

Angle

A coarse slot for every setting

Five angles, five coarse channels. Nothing shifts position when you change the setting, so the wheels meet the blade at the stated bevel each time. A reference guide on the back pairs every number with a knife type.

Wheels

Resin diamond for the finish pass

Once the tungsten stage has shaped the edge, the resin diamond slot takes down the burr those coarse wheels leave behind. That second stage separates a blade that cuts from one that merely feels rough to the thumb.

Grip

Scroll the dial, anchor the base

Changing the angle feels like scrolling a mouse wheel, so you can do it without looking down. Two silicone pads underneath lock the body to the counter, which leaves each hand with one job.

In Use

Serrated teeth and folding knives too

The scissor channel and the adaptive fine slot widen what this one covers: serrated bread knives, pocket knives, Japanese and Asian profiles. Light downward pressure is all the spring needs to close on the blade.

From the sharpening bench

Let the spring do the work in the fine slot. Press down gently and pull straight through; driving the blade deeper only loads the wheels and pushes the edge off the angle you set.
