I recently stumbled upon this instructable, and it got me thinking; what else could be done to improve the humble hammer? I had some ideas in the back of my mind, and when I saw the Hand Tools Only Contest I decided to stop procrastinating and get to work. After all, what better entry for a contest about hand tools than a hand tool itself? My updated hammer has a screwdriver with interchangeable bits, a ruler for rough measurements, a magnet for holding nails and screws, and a bottle opener for when the job is done. I've used it a couple times, and I find myself using all the features; I assembled an entire IKEA bookcase using only this hammer. If anyone can think of any other additions to the hammer let me know!
Thanks to everyone who voted for me in the Hand Tools Only Contest!
