How to sharpen an engineer’s scriber made of

tungsten carbide

Other equipment you will need:

Continuous diamond stone

Make sure you use a continuous diamond sharpening stone and not an interrupted one as this will not be as effective, and may damage the tip of the scriber.

Cutting fluid

You should use a specialist diamond abrasive lapping fluid with your diamond sharpening stone.

Sharpening the scriber

Step 1 – Moisten stone

Moisten the surface of your sharpening stone with the cutting fluid.

Step 2 – Position scriber at correct angle

Hold the scriber in your dominant hand as you would a pen, at an angle of between 30-60 degrees. The closer to 30 degrees you hold the scriber tip, the finer the point you sharpen on it will be. 

Step 3 – Move scriber over stone

Rub the scriber tip lengthways across the surface of the sharpening stone, twisting it between your forefinger and thumb as you go. Use the whole of the stones face for sharpening to prevent grooves being worn in one area.
