tired of marking up your red dot battery cap i think i found an answer

spudger, so what the hell is a spudger, I was looking for a plastic bladed screwdriver and didn't find any and I stumbled on spudger tools used for phone or computer work and I had no idea about them

but went to Ebay and found a China seller or 2 that sold them cheap and order some up

they are hard plastic but not brittle  and after a little recontouring they should be that non marring screwdriver I was looking for maybe a wood handle will added for a little grip, easy to do

also in the set there are 2 ends that could be used for cleaning or who knows or ever removing O-rings

just some tools to add to the box and here is where I got mine

6 inch long and about 30 days to get to the west coast

just an idea no more no less

take care
