On the bottom of mine there's a stylized "P" followed by "Porlex", then on the next lines it says "JAPAN PORLEX" and then "Ceramic grinder for outdoor use"**. Then there's an address, phone n° and patent n°.
On the central burr carrier, under the star-shaped effort, it also says "Japan Porlex".
First time I used mine I let my index finger dangle and ripped the nail down into the quick on the crank: either fold it well under or keep it sticking out straight.
** shit, I've been using mine indoors.
