Umbrellakind

An umbrella without a canopy and with several long razor blades in place of the ribs. It is presumably opened and closed via some mechanism on the crook handle (as was how John opened and closed it). John created the Barber's Best Friend by combining Dads Straight Razor with the umbrella that was formerly in the study. It cost a mere 2 units Shale and 8 units Mercury to make. It would appear that the Barber's Best Friend would be a perfectly serviceable weapon of combat, with its long reach and multiple blades (supposedly) capable of dealing tremendous damage, possibly even multiplying damage per blade.
