PFM Connector Wrench (Tool D36)

This square shaped wrench is used to remove the shell/barrel connector in a Sheaffer PFM fountain pen. Though the connector being removed is round, the hole inside is a square, hence the need for this specialized wrench. The connector is the black plastic piece that holds the front end of the pen to the barrel. The plastic connector has different threads on each side, which is why it often gets jammed and cracked or broken. 

This tool is a classic design that Dale saw in another Pengineer's tool crib and has remanufactured for Pentooling. 

We also sell a replica of the plastic connector that is an exact match to the original Sheaffer part. The connector is round with a square hole. (offered on this listing, after the tool)
