The cross peen (or pein) hammer is an old cabinetmaker's favorite. It has a standard round face on one side of the head and a flat peen at 90° to the handle on the other side. The flat peen on one side is ideal for assembling delicate joinery and seating narrow pins (hold the pin between your fingers – the flat peen won't pinch your fingers, it will slide between them).
Please Note: The weight listed refers to the weight of the hammer head, not the whole hammer.
