Jerry, if the wife asks how much that Bruno blade was, just look her straight in the eye and lie. I did the very same thing with Savage 99 rifles. Plus the wife will never notice a new razor. Its just another razor.
The best I ever did, was buy a shotgun and give it to a friend. He was told to bring it to my house and give it to my wife with the message "Thanks for letting me borrow it". Brilliant!!!
