This is an entirely new tool made of lightweight aluminum measuring 20 inches in length, enough so an entire section of shanks or hammers can be clamped at one time. There is a rubber cushion inlay on each side of the jaws to prevent marring of the hammer shanks. This clamp can be used for three different operations: shaping or roughing of grand hammer tails, cleaning old glue irregularities from hammer shanks; and dressing the striking surface of the felt hammers. The Jaras clamp is a lifetime tool that will drastically reduce the time needed to do these three operations.
