Interesting old cue stick trimmer. Basically this is meant to square off a cue stick if a new tip is being put on. Good shape and would probably work just fine if the blade is sharpened a bit. Sort of works like a giant pencil sharpener but with the blade positioned to flatten instead of sharpen. A little over 5 inches total length. Cool billiard related antique to have sitting around the pool room for conversation purposes. I think this dates to right around 1900.
