Sharpen rotary cutter blades?

[Northmount]

I see a 45mm size that fits Tandy's rotary cutter blades.

You can get a nice edge on the rotary blades with this sharpener.

For all the use my 60mm knife gets I can buy over 60 blades for the price of that sharpener (£8 per 10). That will last me several years

I don't bother sharpening the 60mm blade in my knife

a. I'm rotten at sharpening

b.a new blade is fairly cheap

  c. those blades are wicked sharp, and the risk of bleeding all over your workbench is fairly high!

Utility knives are much easier to sharpen, but rotary blades I'd just replace, and I don't use them nearly as often as my utility knife.

I put the blade on a bolt and tighten a nut against it and put it in a drill and spin it on the edge of a stone. Works pretty good once you find the right angle.

That is an excellent idea. I may try it
