Small Engine Repair Ki-Sol Tools Holder Spanner Wrench

This is a very nice set of special tools for the repair of small engines. KI - SOL Corporation ST Louis MO. is a maker of tools for small engine repair. These are lightweight tools but look to be very precision made out of aluminum alloy. I'm not sure of the exact application but it looks like a holder and special wrench for loosening a special nut. The wrench is marked # K114 and the holder is K167.
