Ha. Ok you all are right that no one will ever agree completely, but is there no common ground at all?
Are you saying that some will disagree that diamond stones, used correctly, are the fastest cutting when compared to other stones with the same grit? From what I have read so far on the internet that seems to be the opinion I come across the most.
Heavy Handed, you don't agree with most of the (very) rough draft. Could you elaborate? Any things you do agree with?
I agree that diamond plates are a bit less forgiving cosmetically, and polish not so well at the low to middle. Is tough to make many more generalizations, because diamond lapping films are fairly forgiving and require water or oil to prevent loading, also polish very well. In general I find a well- matched waterstone to cut faster than a comparable grit diamond plate.
The Arkansas stones I find to be very unforgiving of more pressure - they are prone to glazing moreso than any other media IMHO, so light pressure is best. In general, only waterstones are forgiving of larger pressure variations, and then only when roughing - to finish one should be using a feather touch on just about every media (Washboard excepting
).
The category of man-made/synthetic is way too broad. There is a huge difference between a quality Norton India stone and a hardware store AlumOx stone, AlumOx lapping films. Likewise a big difference between a vitreous SiC stone, SiC wet/dry, and SiC jointering stones, though in general SiC is the most forgiving due to its high fracture rate in some forms.
The waterstone category also a bit too broad, as they come all over the map in terms of price and how well they work on given steels. Some of the stones intended for tougher steels might not work as well on lower RC cutlery as something like a King stone, and the King might not even be able to touch some of the wear-resistant steels at all.
In general I also do not much care for describing oil-based stones as "messy", they often require less fuss and overall mess than waterstones, and using ceramic, diamond plates or wet/dry with no lube is just as likely to leave your fingers and possibly your shirt stained with swarf (though admittedly it will wash out more easily than oil!).
Generally speaking, aside from the less expensive combination stones, most quality stones all run in a fairly reasonable range, though putting together a real comprehensive set can get expensive.
OK, so that's my response - now in all fairness if I had to make a chart, what would it look like?
Truthfully I don't think I could make a chart, only personal recommendations, generalizations, specific responses to specific questions. An actual chart would require a ton of info specific to each entry based on abrasive and binder, and at least a third of it would be subjective based on reported usage and opinion.
