Attachment for ice auger that shapes the bottum like a funnel?

[mac]

I saw one of these somewhere a few years back. You were supposed to attach it to the auger and after you cut thru the ice the arms flipped out and shaped the underside of the ice like a funnel so that the fish got started up the hole without catching on anything.
Does anyone have one, do they work and where can you buy one?
It would be great, because you could get by with a 6" hole.

Back to the top for one more try. Must be there is no such animal or they don't work.

I see them available at Scheels outfitters. Next time I go there I will look for you and get the name of the unit.

I know what you are talking about but can't remember the name of it. I know that alot of the bait shops in the Mille Lacs area sell them. I will check next weekend when I am up there.
