Restoring manufacturers logos/stamps

[orquiza]

On the advice of a friend, I applied Bar Keepers Friend to my 1950s Sabatier 10" chefs knife to clean her up. To my horror, the maker's stamp –*THE K-Sabatier stamp that I know and adore – was partially lifted. It's still visible when held to the light, but not as dark and bold as before. And it completely pains me to see.

Does anyone have advice on how to restore a manufacturer's logo, stamp or trademark? Help!

About the only way is to remask and etch the logo on again, the factory could do it if they still had the original masks easily, but unless the logo hasn't changed in 50 years that's doubtful. Unless that's possible I recommend not applying any sort of abrasive cleaner (comet, barkeepers friend, pretty much any powder based cleaner or "non-abrasive metal polish) and trying not to make it any worse than it already is.

Thanks, Yoda. I guess I'll have a really 'authentic' Sabatier from now on. I figured it was pretty much a lost cause. A lesson for the future and the rest of my carbon steel knives. Besides, I think trying to get the an etching from Thiers, France from the US might pose a problem!

You can very carefully apply "cold blue" in the etch. Cold blue is commonly available at sporting goods stores. It is used for touching up bluing on guns.
