Always missing the right tool
 

I have 4 lock ring tools, but no pin tool!

Long pointy forceps work in a pinch...at least for disassembly

Pin tools are easy. I carry this one in the toolkit, made it a long time ago with a pair (that is to say, one for each hand) of pliers and a file and a bit of hard steel wire.

Mgopack,
If you are talking about the almost never seen lock ring that takes a pin spanner to remove you can do what I did years ago and grind down the Hozan tool on one end to fit into the lock ring. With as many of the flat sided ones as you have you should be able to retro fit one of them. Smiles, MH

Needle nose pliers work when I did not have a pin set.
