The Arno burnisher carries two super hard and polished solid carbide inserts. Polished carbide is one of the hardest materials available (almost as hard a diamonds!) and is the ideal burnishing material.

One edge is cylindrical for general use. The other is triangular with a small radius recommended for sharpening super hard scrapers, curved edges or when a larger hook is desired.

The inserts are slightly tilted to lift the handle above the tool being sharpened. It has an integrated twin finger guard to keep sharp edges away from the hand.

These rubber microscope eye guards have an inner diameter of 34mm (1 5/16 inch) mounting size.

Will fit microscope eyepieces that have a 34mm (1 5/16 inch) outer diameter. The eye guards stretch slightly by 1 mm. Please measure the outer diameter of your eyepiece to ensure fit.

For microscope eyepieces, not binoculars.
