Fingernail barely leaves a mark, but I can see it. I tried the same on some white oak and they marked similarly.looks like African Mahogany or possibly Spanish Cedar. Does it dent easily with your fingernail? Is it more similar in weight to black walnut or poplar?
Not waxy or oily at all. Pretty dry actually.heavier than white oak? ok. that may change things a little. is it waxy or oily feeling at all?
The WWW images I see look pretty darn close!My guess is river birch
Those photos seem to show pores that are too big for river birch. The pores of the river birch I have seem to be somewhere between walnut and cherry.
