The brand name is Kikushige 菊重 from first photo. Can't make out above it.
Second photo says Sakai 堺 meihin 名産 (famous product of the location) then 優良品 yuuryouhin meaning something akin to "excellent product". But the interesting thing is that Meisan 名産 is written right to left. This suggests that the knife may have been made prior to 1945. After which Japanese, when written sideways became written left to right. The kakumaki being metal (brass?) and the extend of wear on the handle would support this possibility.
The photo of the kanji on the blade is very worn but I would "guess" that it simply said Tokusen 特撰 meaning Special Selection.
