Better than a chisel for cutting holes for rat sets?

Haven't tried it yet....

I made a prototype hand auger that has a 5"dia x 12" hole saw type head for boring into winter mrat houses. Worked very well the only season after I made it that I had any mrat houses to use it on. Mrats pop has collapsed by 90% in my area the last few years. This year I only came across less than ten winter houses in waters that 100's were normal. Same lack of mrats has made me run out of them in any number left to under ice trap them with baited BG"s where I would go to a 6" auger(cut overlapping holes) when ice starts getting over 4-5" thick. I trap a pretty set area so when I catch what I think is a safe number I stop for the season.

I prefer pushups and small huts over drilling through the ice and big huts. I get wet and I'm too old to dig into the big houses. That's hard work.

we use a 10 inch electric. works well.

I use a 10'' for beaver its nice. Can put in a bunch of snare sets quick.
