Hi Tommie,
Like many of the others, mine has to be the bowl gouge with the
Ellseworth grind, I had a gouge I ground with what I thought was the
Ellesworth grind but then Crown tools here in the UK sent their
"Ellesworth Signature" gouge over for a review, the grind was much
longer than I had been using and so much better than my effort,
definitely my favourite tool.
