Abstract
A claw for use in a barrel hoop driver which allows the top hoop of a barrel to be driven beyond the barrel edge thereby allowing barrels for reuse to have their staves tightened without fitting new end hoops. The claw has spaced guide members controlling the effective depth of a blade for engagement with the hoops, the spaced arrangement of the guide members preventing accumulation of wood shavings on the blade.
