Abstract
An explosively operated tool () for driving a fastener into a substrate such as steel or concrete has a resetting mechanism () for resetting a piston () of the tool into a rear part of a barrel assembly () of the tool after each firing of the tool. The barrel assembly () is mounted for axial movement within the tool housing () and co-operates with a mass mounted for rearwards movement relative to the housing () in opposition to a biasing force to absorb recoil on firing of the tool. The resetting mechanism () for resetting the piston () into a rear part () of the barrel assembly after firing is powered in response to displacement of the mass on recall.
