This is a very different deep hollowing tool but it works. As you have the shield on the likes of the Roly Munro or Crown tools, the upper prong acts as that shield. I bought this when Melvyn came to our old woodturning club to give a demo and lessons and made some very nice pieces after that. The handle is about 59cm long and the blade 26cm. I need the space so am selling it cheap.
We are in Starcross but do come over to Exmouth most weeks so could drop it off
