Can I say you buy one and use it befor saying its "Bull"
I watched a joiner using one of these to give him a perfect(not near perfect) half moon profile in the taurus skirting and it was if the joins where done by machine.
So I bought one and it pissed(shaved) through the wood like a knife through butter. You have to shave the shape on the outer face though because sometimes the wood splinters,but it doesn't matter about the back of the taurus as that goes against the wall.
