I rarely have to bust ice on the ponds. It got down to 0 last night so the ice is pretty thick. I about worked myself to death using an 8 pound tamper to smash holes in the ice. I found an old tool in the barn that worked better but I don't know what it is. I am sure it is much older than I. I got it at an auction "bundled" with other tools. It is on a handle like an axe. It has a wide "hawkbill" blade at the end and the edges are sharpened like an axe. The whole head is about 16" long. It cuts through the ice so instead of busting it the ice can be cut out in big chunks. What is the name of this tool? What types of tools do ya'll northern folk use for ice busting or do you just use water heaters in troughs?
