Without hammer really can not do any repairs. Depending on the intended use locksmith, joiner, geological and even medical hammers. Between themselves, they differ in shape and size.
At this point in the shops offer a wide range of hammers, so to make a new one from scrap materials does not see the point.
In my opinion, this idea is not worthy of attention, so I put only 2 points.

Improved hammer with his hands It is made of two parts: a bolt which serves as a striking element, and a metal rod. Which in turn serves as a handle. T-shaped bolt is welded to the rod.
The threaded part of the bolt is drilled groove with a slight recess in which the author pasted a piece of tape. Due to the presence of the magnet the nail is fixed in the groove and, according to the author, the nails can score with one hand.
In my view, such a design on the contrary complicate the process and reduce the accuracy of driving, as there is a strong likelihood that the nail-head at the moment of impact will fly out of the recess in the groove.
I also did not like the pen, or rather its diameter. Hammer with a handle is uncomfortable to lie in the hand and can slip.
It is noteworthy that the author of the handle wrapped with plastic shrink for the convenience of working with a hammer.

At present, the market of construction tools there are many hammers of different shapes and sizes. Their prices start at 90 rubles.
I think everyone can afford to choose the right tool among such a variety of hammers. To make something like that, I do not see the point.
So I put only 2 points.
