A lot of people use a bench type belt sander. I takes a steady hand and patience. The longer the platen the better. If you go jointer or block plane, the cutting knives/blade must be sharp to produce results without tearing out. Reducing with a bandsaw also takes a steady hand, but isn't meant to get really close, just remove most of the waste. One of my favorite tools to use on boo is the toothing plane. It doesn't remove too much and no splinters! If you use a block plane, I would suggest wearing a leather glove. A sharp plane goes through boo easily, but splinters do happen!
