The process of making this hand tool is first of all material, followed by processing technology and heat treatment technology.
With 5mm 45 steel, after punching and blanking, when blanking, you must first draw your hand-drawn development drawing. The actual blanking size and outline drawing must have data and technical requirements, so as to make an accurate blanking die and get this manual blank.
Punching or drilling is to process one Ф 6 hole and two Ф 5 holes (but you can't find the accurate positioning dimensions of these three holes, the requirements of the shape and position tolerance and the matching tolerance of the holes on your drawings).
Bend 90 degrees in two places. Any steel has its minimum bending radius limit, but in your drawings, there is no R at the bend, and it will break when bent. )
At the position of two Ф 5 holes, maybe two small cylinders should be installed. Transition fittings or post-weld grinding.
Grind burrs and corners.
Heat treatment and quenching of one or two small cylinders and bending parts require certain hardness and rigidity.
Heat treatment 2, the whole part, after pickling and alkali washing, becomes black.
If you want to take this move, you can use it. Generally, you have to go through these processes.
In addition, there are many mistakes in your drawing, especially the position of the two Ф 5 holes is very important, otherwise it can't be used.
Ok, that's all, for your reference only. Do it yourself
