Ok so I recently purchased my first dubl ducks on eBay 1st was a Bresnick Redhead 2nd was a Bresnick Puma an last was a Twin duck special #1. All three were under 30$ so I feel I did good. Now the reason I'm posting here is because the Twin duck has a good size chip in the middle of the toe so I plan to shorten the blade. That's where all you more experienced guys come in as I would like opinions on how to fix it. I've restored quite a few of my other razors sanding buffing rescaling so I can do the work it needs just wonder how to go about it. Should I do it by hand with sand paper an files since this is my first attempt at shortening or should I go "MORE POWER" an use a Dremel/Dotco or a grinder?
