Ultrasonic cleaner to remove root burr...

Good thought, John.

If that's not asking too much, do you think you could :
- Try this method after just SG grinding + leather wheel/PA 70 honing, and see how BESS scores are affected ?

Um, that's exactly what I did.
I was aiming for the best possible grind and hone i could do, and so for the first time ever I hones on the front jig holder and took extra care to adjust the angle in small increments to break off the burr as carefully as possible. I think that also will become standard practice in future for me.
I only use the standard leather wheel with the Tormek paste, but I'm keen to get another fresh wheel and try the Veritas Chromium oxide paste. This is what Dr Verdim recommends. 

Wow, the scores you mention before using the USC are impressive. Like 80 without stropping. Thanks for the answers, and you got me wondering what a suitable USC would be and what it costs... I've been looking around and saw some 6 liters dual transducer 40kHZ cleaners around 250 EUR.

From personal experience, go for the largest capacity ultrasonic cleaner you can reasonably afford. I guarantee you'll be throwing a lot of other items in it once you've experienced what it can do.

What is the ultrasonic power of your ultrasonic cleaner?

Am I the first one in the history of the world to discover this?

Sorry to burst your bubble but not really. I could not find any reference to deburring knives with ultra sonics so this may be new, but there are people deburring parts post machining using ultrasonics so the technique is not new. From what I can find it is extremely effective and your results are consistent which what I see on machined part deburring.

Working with ultrasonic plus plates or needles may scratch the blade and eventually round the spine.
There are diffenent liquids. Ask a dental technican or an optician for liquids working well with carbon knifes.
