If all you want is just the quick result, you don’t care
about the thinking process, etc, etc, then, these may be
the right tools for you.
NOT the cheapest option, but surely the fastest way to
hand sharpen the knives.
There are a lot of misinformation floating around.
I recommend Atoma (by Tsubo man, Japan) over other brand.
(In a long run, they are more economical than other options, as
Atoma sells replacement diamond film.
Yes, they do wear out, in the end.
With the other brands, you’ll have to throw away your diamond plate
and will have to buy a new one.)
