Homemade Chisels

Quoted text begins.The Trow and Holden website specifically recommends against water
cooling a carbide-tipped chisel when sharpening, as they say it will
lose its temper.
End of quote.

Thanks Bill and John,

I stand corrected.

I knew enough not to quench after soldering. I usually don't overheat on
grinding anyways. I would imagine that gemstones have a lower tolerance. The
chisels have stood up well so far.

Here's the link to Trow and Holden. I just looked it up.
