I've got two. Gave one away a few years ago or I would have had three. Both of mine were made by Eskimo. The first one is no longer available. It is basically their redneck chisel CH7 Economy model. Except mine is a two piece unit. The two pieces can be screwed together in either end. In other words, the handle part is hollow and will fit over the solid end and the solid end is long enough to contact the threads that are in the handle. You unscrew it, turn the handle around and screw the solid end back into the threads. Not fancy. The chisel is just a flat blade. I keep thinking I'll get around to grinding it into a 'Mil Lacs' style head.
The second one is the newer CH12 Redneck chisel. It is two pieces too, but it uses a clevis pin to join the two ends. It has a very aggressive chisel point that is kinda like a double 'Mil Lacs' design.

I keep the cheap one in the truck for reconnaissance missions. If I'm driving around and see a promising looking piece of ice, I can check it for thickness in a couple of seconds without using an idiot auger, a.k.a. rock. And I don't risk dulling the blades of a real auger in shallow water. It's a lot easier to drag around and I don't have to leave an expensive auger sitting in the back of my truck to donate to the sticky fingered masses.
On early ice, when I'm actually heading out to fish, I carry the newer chisel. If I can punch through the ice in one hit, it's too thin to be standing on. If I punch it down and it doesn't go through, I keep on walking. Punch once and it goes through, it's time to back track.
They also work well to taper the bottom of your hole. At Fish Lake, I like to drill a hole with my auger, and then taper the bottom of the hole like a funnel. It's easier to get a fish up into the hole if the bottom of the hole is tapered.
Watched a guy using a homemade job at Fish Lake many years ago. Most impressive example of getting through the ice that I've ever seen. He cut a hole through 24 inches of ice almost as quickly as I could drill with my gas auger. And his hole was over a foot in diameter, while I was stuck using a 10 inch hole.
