Every tweezers I used to date emphasize only the narrowness and angle of the tip, but the inner knurl is good. At the tip of the slippers, it was difficult to use because it was dropped off or changed its direction if you grabbed a thin part, but this is good. I chose a little place not thin, but it is good as an aid to soldering.
I purchased P-86-125. Width of about 1.6 mm per tip. There is a jagged inside, as forceps type as the tweezers race. The wall thickness is thin in the vicinity where it becomes a spring on the opposite side to the tip. Even if you put your strength, it is a tool that you can use properly, with its tip never going backwards. Although there is no finish like a high-end tool, it is necessary and sufficient. (I think that it depends on applications such as disliking magnetization or dare to magnetize it) There are various kinds of stainless steel, but this is what arrives at the magnet.
