need help translating writing on koshirae and blade

Hello,

I got this cute little tanto with intersting koshirae, it has writing (maybe a poem ?) on it and also on the blade that rather looks like a signature. Can someone translate it for me please?
thanks in advance
regards
Peter G.

poem

It's a poem, signed "Takatoku".
Translating the poem itself would require some research...
