Paul Mitchell Diamond Sharpener

The Paul Mitchell diamond sharpener is well known around the world.
It is equally of use in the home for all sharpening jobs, and on the farm for knives and blades of all sorts.
This sharpener is dual-ended. The fine-pointed end tapers from 6mm to 1mm diameter.
The broad end is oval shaped, with sharpening surface all over, from 15mm to 10mm width.
The fine-tapered end files the smallest of loops perfectly, and the broad end sharpens longer surfaces. Use a petroleum-based liquid lubricant (dip in kerosene) when using the sharpener, to keep it unclogged.
Length 27cm.
