It's something that goes at the end of two sticks to pull something out at an angle, like the back of the hammer.
Edit: Wait. It's not a tool head. Wouldn't make sense. I'll be back.
It's the end of something that something else slides into. To screw the two screws into a surface, and then push a slide part into the slit, and the angle in the part holds stuff together?
Man I wish my wood burner came with an attachment like this. I use it to smooth certain parts of 3d prints, but the tips I got are all pretty small so it's not good at smoothing large areas.
Yeah I've seen a couple. Problem is I still can't figure out exactly what temp I need to be at to melt the PLA without it burning or sticking to the melting tool. It seems to have such a specific temp where it all works but I am not able to replicate the same temp with the dial. I got a Lazer thermometer and the dial on wood engraver seems off by a good margin and not always in the same amount.
