I've never used one of them, but I recall hearing of them in the past. A shearer for laminate flooring.

Not as expensive as I thought, but I have no idea if this brand is cheapo in its class or not.
I found it via tripping over this video....

I wonder also whether you can rent it? Maybe not at your local rent-all, but at a flooring specialist wholesaler.
