The DoubleRock Staple Set upholstery tool is terrific at setting staples that have not entered the wood completely. Just place the head of the tool on top of the staple and with a slight tap on the end it sets the staple fully into your project. A must tool when working in a tight area where the head of a hammer will not reach or in a welt channel.
