Finger Saver / Hammer

Finger Saver
Finger Saver

This is a hammer composite with two parts and can provide the most safe way to nail. The first part is a hammer with elastic bar which can be bended for momentum. The second part is a nail holder with metal bar. We can bend elastic part for knock the solid part to nail-in the front of a nail, which is the most dangerous part through whole process.
With the slidable switch, we can change it between a normal hammer and an elastic hammer for different needs.

Except the advantage of safety and easy. It’s also very useful for people who are feeble or weak sighted.
