The end grain looks exactly like the pic you have posted, so you’ve convinced me.
Good points, both of them. I like to think I am fairly good at spotting and identifying timber but this one stumped me.
I have mostly dealt with Oak, Ash, Beech, Pine, Jarrah, Walnut and Maple. The only things I have which are bamboo are a chopping oard at home and the slats on my kamado grill fold out shelves. Both are very light in colour.
