Facom Titanium Combination Wrench-11mm (40TI.11) - The McLaren F1 was for many years the fastest street legal supercar ever produced. Much was done to lighten the vehicle including equipping it with titanium wrenches for road-side emergencies. These wrenches, mfg by Facom, were in excess of $350 each when they were produced 18 years ago. I have 1 extra 11mm size available outside of the 3pc set.
