Tungsten Carbide Insert Diamond Sharpening System

This system makes it easier and more comfortable to sharpen TC wood turning inserts on a diamond credit card. The insert holders can obviously be used to hold inserts being sharpened on any abrasive stone, but the credit card stone holder keeps that type of stone from moving whilst sharpening. The sizes of the inserts catered for by this set are shown in one of the images. The set I've based this on is:Deefine 18.3" Full Size Carbide Tip Wood Lathe Turning Tool Kit, Lathe Roughing and Finishing Hollow Tool with Diamond Round Square Carbide Inserts for Woodturning (6pcs) You need six 5mm x 1mm neodyminum magnets for the card holder and one each of them for the insert holders. Four 10mm diameter rubber/silicone feet are used to stop the card holder sliding.
