Do you really believe, even stipulating your definition of "freehand", that nobody before 1937 ever just had at it and carved something that significantly diverged from the standard shapes of the time? I don't. You don't "invent" something like that (did I mention I invented deep breathing?) although you can be the first to market it; I doubt that took place in 1937, either, though.Marx made many pipes that simply didn’t follow any rules regarding standardized shape and marked them commercially as such with words such as Benchmade and jumbo. He had a line that followed the standard shapes as well, but somewhere decided to let the carvers have at it. This was elk before the Danes. Free hand is not a term used to describe method as much as adherence to standard shapes. I am not sure why that would be considered absurd?
To OP: I'm not disparaging the pipes or their historical interest. I just got a chuckle out of the notion that something so obvious, all of a sudden, like in a vacuum, with no prior influences or moves in that direction, invented--in 1937-- "the freehand pipe", regardless of how it's defined.
