De Buyer Trium 3 Step Blade Sharpener

The TRIUM Diamond Cams Pro sharpener easily and quickly restores perfect sharpness to any type of knife. The Diamond Cams - a patented system - sharpen the blade with a precise cutting angle: just slide the blade down and back, between the cams, to restore a finely sharpened bevelled edge.

It has 2 slots: 

1. Coarse grit sharpener for dull blades 
2. A 2-stage slot for fine sharpening and honing between the Diamond Cams.
