Recipe containing plank - can't find last ingredient

[KhaelaMensha]

So I found that you can use a plank, a small stick and a stone and a fourth, unknown ingredient to craft something. At least, the crafting screen still shows a fourth, empty slot as it does with other recipes. I have tried a lot of stuff, but can't seem to find the missing ingredient to craft whatever it might be. I have looked at all wiki pages i can find and also searched in these steam discussions right here. No hits.
Any help or thoughts are appreciated.
Those are the things I tried to use myself (besides Plank, Stone, Small stick - adding another of any of these three doesn't work either):
Stick
Long stick
Log
Rope
Feather
Bone
Charcoal
Stone blade
Banana leaf
Brazil nut shell
Fish hook
Bone needle
Coconut (complete one)

and probably a few other things I can't remember right now.
If anybody has a great idea or finds what this recipe needs, let me know, I'm quite curious what this contraption might turn out to be :-)

I dont believe that has been released yet?
Sometime Creepy Jaw adds stuff prior to the release.
It offers to craft but without the BP it's just a that.
I have been using the plank for firewood :)

Ok, I was afraid that this might be the case. So let's wait and see what will come in the future :)

Maybe theyre addin a maicuahutl?

Its probably the bow drill. Recipie works in Challenge mode, but not in sandbox survival.

Plank
Stone
Stick
Bow

I had hoped maybe a raft plank
The drill plank kind of makes sense as that idea is used in other survival games

Your welcome. :) I still wonder though, why the devs didn't add this tool to sandbox yet. I don't see any reason not to.
