I don't have the Daddy Barlow but I do have an example of the standard sized two blade Barlow from that collection.
Everyone that I have had contact with, myself included, has unanimously praised the quality of the smaller Barlow. (They are made by Boker under license.)
Hopefully someone will chime in on the larger version. If it's like the smaller, it's a steal at the price. And yes, they are good carbon steel blades.
