Sac Expander (Tool D10)

A CLASSIC PEN TOOL EVERY PEN REPAIR PERSON NEEDS! Since being developed at the start of the iron age, this has been the most often used tool of any pen repair person. Insert the prongs into the sac and squeeze the handles to easily open up sacs so they can be installed on the section with a little shellac. Currently comes in stainless. 

A must have! One of our best selling tool. 

Note: at ta San Francisco Pen Show a few years ago, a depressed repair guy walked up to my table, desperate to find something to use as a spanner to get his Torelli pen's filling unit apart. After he poked and jabbed the divided screw slot with 3 different spanners intended for Sheaffers as well as a number of probes and unrelated tools, with no success, I handed him one of these and it easily unscrewed the split screw in the Torelli. This type of screw is used in several pen brands and consists of a recessed screw with a slot that is interrupted in the center by a shaft which passes through the screw, usually being a part of a piston or a plunger. So you can't use a straight screw driver; maybe one with a slot in the middle of the blade.
