Water-cooled Tormeks Means No Edge Overheating

[BeSharp]

Vadim from KnifeGrinders.com.au is at it again - he is posting on YouTube a 10-video series, "Overheating in Sharpening". 7 videos are up so far.

Most telling is that Tormeks, with their water baths as coolant, do not even merit testing : )

Larrin Thomas, of knifesteelnerds.com fame (and has a CATRA sharpness tester in his garage!), wrote about steel softening from overheating: https://knifesteelnerds.com/2019/04/08/does-sharpening-with-a-grinder-ruin-your-edge/

(BTW, I highly recommend his book, Knife Engineering: Steel, Heat Treating, and Geometry)

I have ordered some honing coolant and look forward to trying it on my two Viel belt grinders (for repairs only; not for sharpening!)

Someone asked a few days ago how much to sharpen a knife. Yes, Tormeks are slower than a bench or belt grinder. With a Tormek, sell quality and value, not price.

Chip,

Interesting comments. I always follow the KnifeGrinders videos with interest.

Over the years, I have become completely comfortable with Tormek's water cooled environment. My fingers are often within a quarter inch of the grinding wheel. I don't feel any heat, nor do I worry about accidents.
