I was at the National Quilt Show this past Friday, June 18, 2010 and saw this tool and was wondering if anyone has it

Alex Anderson's 4 in 1 Tool

Hey I'd be interested in one of those.
It's much handier having the items all-in-one.
My only concern is after the seam ripper gets dull.
I've never found a way to sharpen one so I just throw it out and buy another.
I'd hate to have to do that to this item.
Other than that, it's a great little tool Alex has.
