Hey, a newb here in Indiana. Have a shavette that I have been using while waiting on a restore that my brother is doing for me. Today I saw a post that mentioned the razor being left handed, it was a kamisuri. Up until today I had never heard of a left or right handed blade, been left handed this is something that I usualy take note of. Is this something that I should worry about when looking for razors? And what exactly is the difference?
