I know that the tannin in oak has a tendency to stain or even damage steel but are there problems with other woods? I've got a few different bits of wood someone's cut up for me and I'm presuming the olivewood and ebony are ok as TI offer them for their scales but I've also got some yew and chechen (Metopium Browneii).
Does anyone have experience of these or heard of any problems with them?
Thanks in advance
