I was recently given this turning saw by a kind lady in Yorkshire.
Unfortunately one of the blade holders had sheared off...
This is because the the wooden bit inside the brass tube is only 9mm diameter. So I'll drill them both out and fix them properly. Apparently it was made by Matt Sears (son of John Brown, Welsh Stick Chairmaker) and many years ago I bought a froe from him after seeing his name and address in the back of Mike Abbott's book "Green Woodwork".
This is the stamp he used on his tools -
and I've only ever seen one drawknife with the same mark. He upped sticks and moved to the States in the 90's as he couldn't make a living here.
Hope he's still going but not making wooden tools.
