This old wooden chalkline tool just struck me as really beautiful, most of all for the blue  of the chalk-dyed string, which varies in tone and makes it feels like a painting to me! The spool holding the string rotates on the handle in order for the string to be unwound and stretched taut, and it could certainly be put to use once again, though I'd be very content to treat it like a sculpture and just set it somewhere to be admired.

8 3/8" l x 1 1/2" in diameter. Very good much used condition.
