I have a few questions as I contemplate purchasing a set of stones for myself. A little background info: I purchased a 1000/4000 Norton dual sided stone years ago when I was new to sharpening. I kind of regret this purchase, and prefer to pick and choose between stones belonging to other cooks I work with. Typically I am able to progress through 600/1000/6000 and sometimes 12000 if I'm lucky. I value a sharp knife and can typically push cut paper and pop hairs off my arm when I'm finished. My knife sees a heavy amount of use as well as frequent sharpening, so I think it's time to invest in a set of my own. What would an ideal stone progression be? I was thinking something in the 400-600 range, followed by 1000/4000/8000...thoughts on that? Are higher grit stones and strops heading in to the realm of diminishing return, or is it worth pursuing? I was thinking about getting all Shaptons...I'm not too keen on the differences between brands however, perhaps there are better options out there? Shaptons seem to be reasonably priced and long lasting. I'm curious to some of the differences between the Glass and Pro series as well. I realize a lot of this comes down to personal preference, and that there are many means to the same end. I value many of the opinions on this board and was hoping for a few different points of view. Thanks in advance, and happy birthday to Julia Child.
