Hi everybody, young guy from Denmark here.

I got this strange looking tool in a deal, but to be honest I have no idea what it's for. Can any of you guys clarify what it's for? It's not sharp at all, more like a ig flat screwdriver at the tip and then about 1 1/2 inches up it turns into some sort of drill. This isn't sharp either though. If it's meant to work as a screwdriver I would like to know what the twist is for.

Anders, I tried to brighten up the picture a bit.

Based on the file handle I would guess this was an experiment in blacksmithing. A pretty good one too.

That did the trick, thanks much better now.

If the tool isn't a woodworking tool of some sort, I think I'll do a spark test and forge a woodworking tool out of it if it's high carbon. :)

It was typical in the 18th.C and possibly 19th.C. to make screwdrivers with twisted blades. I guess they thought it looked tricky. That is not an old looking handle. It looks like a file handle. The blade could be old,or a blacksmith made twisted blade. Any markings on the blade? I see screwdrivers like that in old reprinted English 18th.-19th.C. tool catalogs that we used for research. They kept the same illustrations for many decades in English hardware catalogs. If an old blade was jammed into that file handle,the name might be found up inside the handle,if you could pull the blade out easily.

I don't have the engineering background to back this up scientifically, but it seems to me that the twist would increase the blade's resistance to torque.

. . . or, vice versa . . .

Doubtful. I suspect it was something done because it was cool.

Now you know what to do with all those old Auger bits that aren't used any more.
