This is an ice drill used for smelt fishing. I've used it about twice and then stored it in a closet. There is no rust on the blade. It's quite sharp. The blade diameter is Φ15cm. The screw part is 50cm long, and the total length is 1.5m. It folds in half and is secured in the middle with a screw. It's made in Sweden. The middle is secured with a butterfly screw that you tighten by hand, but the screws holding the butterfly screws on both ends are 13mm, so I'm including the tool to tighten those screws.
