We have to store many kinds of tools in spite of using them rarely. It is p big problem, because many kinds of tools occupy lots of space and sometimes we can't remember where did we put them. To solve it, we design 'Multi Hammer'. It is the combination of a screwdriver,
a tape measure and a hammer, which is always used at home. If you use it, you will not have to find tools which are scattered. And it occupies a little part of space.
