I respect the opinions enough on turning discussions here to go ahead and share my thoughts on the subject. I've been using the 40/40 for a long time now and, if pushed, I have to say that I honestly do not think 40/40 is just that much of improvement (if any) to turners that are using any of the versions of the swept-back grinds (Irish, Ellsworth, standard/English, etc.). I have no problem with the sharpening requirements for the 40/40. I find it to be a pretty simple and quick process with a little practice. What I do find is that there is no difference in the quality of a cut between the 2 grinds (and I have compared cuts on 8 or 10 different woods) PLUS it will only get you about 2/3 way down inside of a bowl where then you have to shift to a different tool (due to the bad angle) to cut the bottom (a steep/bottom grind, scraper, or even one of the swept-back grinds). On the other hand, a swept-back grind is without doubt or argument (ha) a more versatile setup for a turner. Depending on the size and type of what you are cutting, there is way less tool swapping whether working inside or outside of a vessel and whether or not you are making heavy (hogging) or light cuts (shearing). I love the process of looking for a better turning technique or a better tool...but I've never really developed a taste for my own bathwater. Yes, it "takes all kinds"...but I would be interested in reading your own truthful opinions on this subject.
