Jarrah, New South Wales blue gum, river red gum, Red mahogany, brush box, Tasmanian myrtle, and a whole range of Eastern Australian hardwoods collectively sold as Forest Red. The colours are often call red but that is just the general average. These are mostly eucalypt species although the myrtle is actually Antarctic Beech and the colour varies depending on which end of Tasmania it was sourced from. All are hard, tough, heavy and last forever as cutting boards. Expect to use carbide machine tooling as HSS will dull in an incredibly short space of time. Cheers
