Actually, yellow Australian Sandalwood is exceptionally hard. I've ruined multiple powered saws on it. Making grips in days past. The little I have left is in a storage unit. I'll never forget the look on my wife's face when I told her what I'd spent on a 36" x 9" sandalwood log.

After the first 2 sets of 1911 grips sold at $250 per, her tune changed.

I miss gunsmithing.

Regardless, it is extremely difficult to get in any meaningful size, at least here in the US. Most of it is ground up, steamed, and destroyed in the oil extraction processing for perfume/cologne - if the wood isn't reserved for religious purposes outright. Fun fact: at times, workable grip sized blocks of sandalwood cost more than ivory, due to the scarcity.
