"How would I get on better with one of the above mentioned knives...?"
That's not really something that can be explained easily in words, but if we ever meet up I have examples of most of the available hooks and let people try them out, that is the best way to find what works for you. I have been forging hooks for my bowlturning and for spooncarving for 15 years now and it is not easy to say why one tool works wonderfully when another quite similar one doesn't, simple fact is the Helgesse hook works wonderfully.
"I would also be interested in hearing how you hone them. I assume they are scandy, so holding the bevel flat on a stone and twisting the knife and stropping at the same time is not easy"
Again not easy to put into words, the inside I only use a broomhandle with autosol, the outside I use stones. My personal set up is diamond bench stones fine followed by extra fine then 6000 waterstone followed by autosol on a piece of planed softwood though use whatever suits you. I lay the knife, bevel on the stone left hand on the handle right hand in the hook, starting near the handle at the top of the stone I draw the knife towards me at the same time raising the handle gradually so all the hook comes into contact during the stroke.
