A plane is a frame, wooden or metal, for holding a blade much like a chisel. It fits comfortably in hand at a fixed angle for removing shavings from wood. Wood grain runs differently along the side and across the end of a board. The block plane is spoken of as being the tool of choice for working, or blocking, end grain. It does that, and so much more. Being the right size for single handed operation, it gets employed for chamfering edges either side or end grain. For ease of long strokes the length of a board its big brother planes come into play, but the block plane is handy, and kept sharp will serve the craftsman well.
