This is an unused Krieghoff Thin Wall 12 ga. Speed Choke Wrench. This is the 5 prong wrench that works with Krieghoff K80 Parcours choke tubes. The handle will collapse into the wrench making it compact for fitting in your choke tube case. This wrench does not fit the standard K80 chokes, only the thin wall Krieghoff chokes. Krieghoff charges $90 plus $12.80 shipping plus tax for this wrench. I'll sell for $80 shipped CONUS.
