This post is a bit of a consumer alert....but this consumer may simply not understand the ins and outs of Japanese manufacturing ties....but let me lay out an interesting discovery.
We noticed a while back that there is an ebay seller from Georgia who is selling a Kyocera CM-50 CF hand coffee grinder, which piqued our interest as it is a larger size than the Kyocera CM-45 which we have proven to be a very good espresso grind capable hand mill. A bit of googling found the same Kyocera CM-50 being sold by Amazon as well. From our investigations this grinder is a Hario Skerton in a box printed all over Kyocera...."Made in China, Glass made in Japan" (and marked Hario). These product listings state that the grinder will grind Turkish (they won't) to coarse (rocks and fines).
The Hario Skerton is a reasonable grinder which on a fine setting will grind an espresso for some machines, depending on tamp and on the machine, and for the price of 40 bucks at most coffee places (Visions for one) it is a good grinder for the money for moka pots and drip IMHO, but does not reach well into either of the extreme ends of the grind spectrum. The Skerton/Kyocera on Amazon sells for 60 bucks and we paid 54 plus shipping to the ebay seller. Research shows that the Hario Skerton may be made by Kyocera and rebranded by Hario as the Skerton.
We have gone a long way establishing the Kyocera CM-45 as an excellent grinder for espresso as well as other grinds and have not found the Skerton (or Kyocera CM-50) to produce a suitable grind quality to stand behind it as espresso fanatics and there may be a bit of a coattails effect here for this overpriced Skerton/Kyocera promotion.
Again, the Skerton is a good grinder for the appropriate applications and at a reasonable price point. It grinds near espresso fine at about 100 turns per tablespoon of beans, it is quiet and has a very good looking ceramic burr, perhaps made by Kyocera. Changing the grind setting is a bit clumsy and the top handle holding nut tends to loosen. If they had included a spring between the top plastic bearing and the inner burr it may have been a reasonable grinder on the coarse range, but this is a simple mod to experiment with.
This is not intended to be a product review, just a note that if you are thinking that a Kyocera CM-50 seems a good idea instead of the CM-45, save a few bucks and get the Hario from a company that does not view it as a crackerjack pepper grinder, and please, NO CLOVES or POTPOURRI!
