Abstract
A hand tool includes a plate-like body having a connection end from which a handle is integrally connected there which includes a first section and a second section. A grip is connected to the second section. The first section extends from the connection end by an upward angle and the second section integrally extends from the first section by an angle and toward opposite to the connection end. Each of the first and second sections includes a wall which is a curved wall and faces downward. The hand tool is punched from a metal board and includes a plate-like body and an extension portion which is then bent to form the handle and a grip is connected to the handle.

A method for making a hand tool, comprising:
- a step of heat treatment to a metal board;
- a step of punching multiple parts from the metal board and each part including a plate body and an extension portion integrally extending from the plate body;
- a step of bending the extension portion to include a first section, a second section and a third section, the first section extending from the plate body by an upward angle, the second section extending from the first section by an angle, the third section extending from one distal end of the second section and being bent toward the plate body, the third section being located beneath the second section and including curved wall which faces upward, and the third section further includes wave-shaped underside;
- a step of bending the first and second sections to have an inverted U-shaped wall so as to form a handle;
- and
- a step of applying an electro-coating treatment to the plate body and the handle.
