Started out making cutting and serving boards for friends and family so the purpose of making them was to use them for cutting juice grooves and finger grooves. I've used two of the four attachments on at least a dozen hardwood boards and they work as expected. The image here is an example of Padauk, Purple Heart Maple, and Cherry, so it's not exactly soft. Remember that any tool is fine as long as you move it into the wood and you won't be able to burn it that easily. I definitely recommend it.
