This is a nice tool for both ice fishers or ice spearing fishers. You can quickly chip through the ice and cut any size hole you want quickly. If you close up your darkhouse for a couple of days - use this saw to reopen your hole. This keeps you from smelling up your darkhouse with gas from a powered auger. This one folds to about 44inches and is 82 inches extended and about 7 pounds, so easy to carry.
This one is sold through Fish's Sporting Toys in Winger, Minnesota
