The Tacwise A11 (type 140) Hammer Tacker is a heavy duty tool for tacking jobs. Extremely robust construction, easy to load and tactile grip. It's extremely weighty and could cause some real damage in the wrong hands. As a tool, it is useful and does the job required. It takes a bit of practice to get used to and a fair bit of whack to operate but once you get used to it is very straightforward. A useful and fairly stylish addition to ones toolbox.
