Anyone have any idea what this wood is?

My first guess is Wenge. When you work with Wenge you find that is quite splintery. That is how you would know for (almost) certain.

ipe

Ipé is usually not that dark. It could be that this is an abnormally dark piece or the lighting makes it look darker than it is.

Ipé will not float. That is one way to check to see if it is ipé.

Both ipé and wenge are very hard, heavy woods but ipé is harder and heavier.

FYI – unless treated, ipé will get lighter over time.

I believe that if it doesn’t float can be Ipe, if it float, can be angico preto (Timbaúba, or Faveira Folha Fina) density = 900 kg/m3

Could it be tropical walnut?

peruvian walnut looks much like that

I think Tropical and Peruvian walnut are the same thing. They are dark brown with even darker brown streaks through it. I’ve seen it used in flooring but it’s expensive.

I was leaning to wenge, as I have heard that it is an irritant to your nasal cavities. This stuff def is, burned my nose even when I jointed a different board as the dust and chips were still in the jointer. According to the people at habit the pile i got that board from is supposed to be all from S. America, but I can’t verify that.
