In reply to Stephen R Young:
I've not heard about it. Have you got any pictures? Any other info?
As for a written history, I'm not aware of anything, though there are many threads on the US forum, Supertopo about ice tool development.
All I know is that during the late 1960s, both Yvonne Chouinard and Hamish MacInnes were developing short-handled steep-ice tools independent of each other. Hamish introduced the steeply inclined pick and the all-metal axe. Grivel were the first to put a bend in tool shafts I believe, but not sure of the date (can't remember the model name either). Who came up with the reverse curve pick? There were all sorts of other developments by other manufacturers in the 1970s - Cunningham Ice Daggers, Don Whillans' Whammer, unusual US tools like the Eboc (early flat formed axe like Grivel's much later Monster series), Lowe's Hummingbird with the tubular picks. Some other quite interesting and successful designs more recently including Camp's Woodpecker and Simond's Piranha.
I have a small collection of vintage short-handled axes myself, but my meagre knowledge is just based on the few snippets I've read online, and talking to people like Hamish, Yvonne and Mick Tighe (who has a wonderful collection of ice axes).
A written history would be great!
