Kozuka signature

Hi,
Could anyone help me identify the enclosed signature ?
It's carved on a kozuka.
Thanks a lot !

Kaneharu ??

The small individual chisel marks are still clear, so perhaps it's not very old.
I'm going to guess "Seki Kaneharu", i.e. KAN818.

Kozuka signature

Hi Pete,

Many thanks for that, I appreciate your quick help.
I concur on the 2nd character, already seen somewhere in other pictures on this website; the 3rd is more difficult to me... and I'm puzzled with the 1st.

Best regards,
