Despite all the dismissive things I have to say about block planes, this particular variety is actually very useful. Its job is to quickly round over the sharp edge of a board to give it a pleasing, splinter-free feel. Very little wood is removed, but the result is a dramatic improvement in feel. You could use a router, file, or sandpaper, but this tool is quick, effective, and gives a very consistent result.
