An inner cap wrench is essential in order to immobilize the inner cap when unscrewing the jewel and clip bushing of a Parker “51”. My version of this tool doesn’t differ significantly from the style used by Parker repairpeople. Rather than a wooden handle, I make the wrench from a single piece of aircraft aluminum and I form and knurl the integral handle; I also provide a slip-on sponge rubber grip (now shown) for those with more tender digits (ok, I use that version).
I am not accepting orders for this tool at this time, but that might change in the future.
