General Tormek Questions / Re: Knife Steel Nerds

I received Dr. Thomas' book, and read the parts relevant to me.  It is really good, and worth having in your sharpening library.

Best description of hardening and tempering and why that I've ever read/heard (not that I have much of either).

I have a second wheel which I use 1µ diamond spray on after it was initially oiled. I use Tormek paste first then switch wheels. I keep it in a sealed bag when not in use. It gives good results on my personal knives, however, none are high vanadium.

In Tormek's own words.  Average 3 microns, but does not give a range. 

A "Perplexity AI" search yields:

"The Tormek PA-70 honing paste has an average abrasive particle size of about 3 microns, providing a fine polish for honed edges. Some sources mention a particle size range from 3 to 1 micron, but the most consistent specification is the 3-micron average"

Old thread and I know Vadim is not with us anymore, which is very sad.

I have question. I'm about to sharpen a M398 knife and wonder if a final strop with PA-70 will do more damage than good after using my other leather wheel with 5 micron diamond paste?

Thinking PA-70 is finer than 5 micron.

Thanks

I've read all the articles on his blog — most of them several times. They're real eye-openers. I'm inclined to trust him, though it's difficult to verify his claims without access to an electron microscope.

Glad to see some progress.
I will not call them and remain standby. Fingers crossed.

Dear friends,

Thank you all very much for your help and support.
Last evening the seller finally replied to one of my messages. According to him, the parcel was sent on October 8th. I will now contact the shipping company to find out where it got lost.

It's a bit disappointing that only after almost a month the seller finally provided me with the tracking number.

Sorry for the trouble, and thank you again for your understanding.

Best regards,
