Yesterday I found a red tip at a flea market for $6. I cleaned and sanitized it last night and shaved with it this morning. A four day set of whiskers and it went thru them slicker than snot. I am very impressed with this aggressive 1957 C 4 razor. Along with it I also got two 48-50 super speeds and a 58 D 1 tv special, all at $6 each.
