Pull my finger
I feel ya. 71 years old and I have arthritis in both wrists.. More and more I go to power stuff for case prep. I have an RCBS motorized case trimmer. And for cleaning primer pockets an electric screw driver. I found a small drill chuck on the internet, that has a 1/4 hex shaft. It snaps into the screwdriver. I then place a primer pocket brush into the chuck. . For a few of my high use calibers [204, 223] I bought two of The Worlds Finest Trimmers. One in each Caliber. Chuck it up in a battery drill and trim away.. Now my wrists hurt just from typing all this..
