Looks just like the Baum Tools item I bought through eBay yesterday, priced about $25 less than the one I bought. Probably the same item, just a different retailer. Mine was sold by El Paso Tool, but now that I've already clicked the big "buy" button I see that Komen Tools also has an eBay listing for that same item, and there's another similar tool, for $280. Oh well; mine is already on the way, and those others would probably break anyway.

Baum Tools makes B334140X5, but doesn't sell to the public. El Paso Tool and Komen Tool are likely just retailers. Wonder what they pay for the tool...
