Kanji Help

[khashy]

This is the back of a wooden stone base I have just received. Any help with the kanji would be appreciated

 

[KenHash]

The first 3 characters are Hizoritogi 日剃研　(Daily shaving sharpener)
After that i see Ju 十　(ten)
Maybe there is a ichi 一 (one) above it. not sure.
Can not make out the last character as looks like a wood knot is in it and
severly faded anyway.

Fantastic, thank you very much sir!
