Hi  
If you just search the word etch in the form you will come up with a multitude of threads on how to etch your blade. 
 
Personally i do not like to over clean my swords unless they are v v rusted and need to be rescued from the red devil that rust is. 
 
But the option is yours to make  
 
Regards
