Thread: Very thin E.A. Berg

This is the type of backing sleeve it would have had, not one of those solid ones (the solid ones don't often come adrift, but the tube ones do!):



The one above is a bit battered, but originally it would have been a tube, slit along its length and shaped at the back. You could use brass, but it wears a bit quickly when honing, or you could find some steel or stainless tube and slit it with a fine diamond wheel that is less than 1mm thick. Helps if you have a friend with a machine shop like Jimmy said, or if you can make a holder for the tube and set the saw - maybe a dremel - fixed in one position, using the tube holder to slide the tube under the wheel against a rail. The saw wheel width should be less than the width of the blade, so it makes a spring-fit.

You can use a fine blade saw like a jewellers saw, but you have to have a steady hand and a number of blades - they snap real easy!

They do trap water, so you might want to seal with silicone or epoxy.

Good luck!
