Some CM tools when exposed to high heat suffer chrome failure.
The nickel plate goes away leaving a brass like finish. Which of course to certain Ebay sellers has to be the ultra rare gold plated version or possibly a brass sparkproof version.
One joker went head to head with reason and proof claiming as his had been found near Ft Knox it was most certianly a special edition made for the military and got rather confused in his story as it went on.
Then the listing got pulled, at least twice and it never sold. The BIN price reflected his amazing stories.
You too can have special gold plated tools by just exposing them to the heat of welding. I did it myself making a few oddball wrenches using old sockets.
The joke is if you challenge these guys with stuff like facts they take a stance to try to support the story (and ultimately price) but they will NEVER back down and accept anything else.
Its like those faked CM long handle flex head ratchets that bear a breaker bar part number on the handle and other makes part numbers on the head.
Sure, its a long flex head ratchet but it is NOT anything Sears sold in the stores.
Sell it as a frankenstien thats cool, pass it off as a CM rarity is fraud.
