Thread: Fox Razor Hone - Goldfisch Wetzstein take your pick

Although not impossible I don't think it's likely the original user replaced his purple Goldfisch Wetzstein with a BBW which in that time was not used for sharpening. The Ebay seller could have put a BBW in it's place but then this person would have had to know there used to be a purple stone in before and would probably have mentioned the rarity of the stone to collect a higher price.

Slurry color can be used to tell the difference between BBW and slate backing, but a purple slurry doesn't necessarily mean the stone is a BBW.

The question you should be asking is how you can tell the difference between a Goldfisch Wetzstein and a BBW before you return a stone that might be very valuable.

BBW have a wood grain pattern as can be seen on the picture ChrisL embedded into his post above. A Goldfisch is completely smooth without such a pattern.
