My brass preparation tools are getting dull at some diameters. Case trimmer cutter and inside/outside de-burring tool in particular.

Mine are made by RCBS, so I know that I could just “send them in”, and most likely would get sharp tools back at their typical NO CHARGE.

I could also just buy replacements for minimal cost. I’m leaning hard this way because the tools owe me nothing after near 30 years of good service.

Question part is this: Have any of you found a good technique to sharpen these tools? Worth the effort or not?
I have some good stones and files, but never tried.

Anyone else tried? How did you go about it?

I regularly sharpen my knives,chisels,shears and sissors.
But I have bad luck with drills and things 'circular'.
My case trimmer is a Lyman;I bought new cutters for it.

No reason to not try.
If you take a hard Arkansas stone and put it against face of the cutter and make a pass or two you will have a sharp cutter for awhile.

Keep the stone against the face of the cutter so it will keep the face of the cutting edge straight.

Same as me. I'm fine with knives and such. Drill bits are out.

I agree William Iorg. I want some good tools in-house before I do though. My "daily dumbass attack" comes without warning mostly. That is why I posted!

I sharpen all of my tools from my pocket knife to my chain saw and even the reamers and lathe bits I use at work, (some of the tooling has bits that we do just change out) most people sharpen the wrong edge of a cutter and then wonder why it doesn't work as well as it did when it was dull!, the reamers need to be touched up in the "flute", not on the edge that does the cutting, just like scissors, you sharpen the back side not the cutting edge.
