HELPFUL HAMMER / Hand tool

General people are afraid to hold a nail with their hands when hammering into the wall.
HELPFUL HAMMER is a tool which has unified the tools that hold a hammer and nail.
You can hammer by using the assistant tool which comes with the hammer to hold the nail rather than using your hands. If you hold the nail through the opened gap, you can hold nails of various sizes, starting with the smallest nail to large nails. This tool holds the nail while simultaneously holding the assistant head, thereby enabling you to firmly ram in the nail.
HELPFUL HAMMER is a convenient and safe hammer for people who fear hammers.
