Kamisori: Kousiyou PIKKA

I got it for less than a 100$ last week. Does anybody knows anything interesting about it? What do the Kanji mean?
It is a very good razor, according to the seller it dates back to the first half of the 20th century, NOS. He described the steel as high carbon/tamahagane, but i do not know whether it really is tamahagane steel. Anyway it shaves very close, after little honing (just my japanese finisher) it is sharp (hanging hair test positive, shave excellent) the blade length is a little on the short side, shorter than the Kanetake No. 1, but a little wider (approx. 6/8). I like it, for me its was a good deal, but I still prefer the easier handling of the large Kanetake 2, which are my most used Kamisoris...
