What is this screwdriver attachment?

Anybody know what this attachment on the screwdriver is for?

It's a cloak of invisibility. It makes it so you can't see the picture you posted.

Conduit reamer. It deburrs the inside and outside of freshly cut EMT.

Klein Tools Conduit Reamer 19352 - The Home Depot

From Klein Tools, the Conduit Reamer works with a screwdriver to ream and smooth thin-wall conduit. It locks onto a screwdriver and can ream both ID and OD at the same time. Comes with two set-screws to fit either round or square-shank screwdrivers.

I think the OP's is also Klein, but the collectible 1912-2012 100 years Titanic Commemorative edition.

It's in need of a replacement blade.

PS: If you are skilled... you can also use that tool as a saw tooth set.

It also looks like it needs a replacement screwdriver
