At first blush, this seems like an interesting idea for non-slip handles on slip-joint pliers. Unfortunately, you can only hold them comfortably with the finger indentations downward. Also, not all hands are the same size. This kind of design involves the concept and process of anthropometry.
According to The Learning Zone:
Finger ridges or indentations along the handle are not recommended. If you have particularly small or large hands, you may find that the grip is uncomfortable because your fingers are spread too wide to allow a good grip, or the ridges in the handle lie uncomfortably among your fingers. Finger indentations also encourage your hand to stay in one position and this might not be suitable for all tasks.
Another dead end in tool design. No maker's name.
I have a pair of similar pliers except mine does not have finger grips. There is tho small print near the hinge that says "Bruno Will" Germany. Hope this help you figure
