I just had a play with a friends hollowing adze and thought I would post a quick comment since I liked it. It was made by Hans Karlsson of Sweden, they are available in UK via Woodland Craft Supplies (http://www.fxferry.demon.co.uk/tools.html) or US via Country workshops.
I am not use if the one I used was the 600g 5cm one or the 700g 6cm one. Hollowing adzes are tools which are difficult to get just right and if they are not quite right they simply don't work. This one works very well and I would recommend it, not cheap at about £90 but I hollowed a kuksa with it and it saved a lot of time with the hook knife.
John had the sheath made for it.
