Hi there!

A while ago there was a thread about "Orihi" kamisori:

http://straightrazorpalace.com/razor...sori-help.html

After my first



I've ordered a second one



and also required a bit more information below,
if someone knows more information about these strange things, please share it ,
especially how old they are, most sources say from the "Edo period", that is: 1603 - 1867,
Sources below suggest the same:




Edo period Artist Kitagawa Utamaro I, Japanese,
first: (?)–1806,
second: 1801




A Whetstone with a Razor, and an Envelope for a Present
Unidentified Artist
Period: Edo period (1615–1868)
Date: 1811
Culture: Japan




shaving the top of Fukuroku's head,
Toyokuni Utagawa III, Artist, 1857



During the Heian period (794 to 1185 A.D.!)
the practice of okimayu (置眉 or おきまゆ) began.
This involved the shaving off the eyebrows and replacing them
with fake ones painted on higher up on the forehead.
It lasted, in one form or another until
well into the Edo period.
