Do you have unlevel blade wire contacts? This tool will level them just by inserting the tool into the barrel and twisting it against the blade wire contacts.
This tool can be used with any PBT epee blade wire or French epee blade wire. Will not work on the FWF/Uhlmann/Allstar blade wire..Will work with any epee blade wire that does not have the taller cup like the FWF/Allstar/Uhlmann type blade wire.
This tool has a recent update and the hole in the center of it from the image is no longer there.
