The information comes of course from Maksim and Toyama obviously does not have the need to keep his relationship with Watanabe private - otherwise neither me nor anyone else would get to it. There is an older mirror version if the Watanabe English webpage that shows Toyama in his workshop:

The photos have very low resolution, but comparing to Maksim’s video from one of his visits to Toyama makes it clear.
As I said - Watanabe might be making some knives. But given his very fast responses to emails, he can’t be spending too much time on n the workshop. Whether some if his family members make knives is something I can not say anything about. He did inherit a large workshop, but according to Maksim it us geared towards lower end large volume production and supposedly it is not in use.
And about the handles - it is all a matter of the source, it is actually not very common to find knives with good quality handles as there is shortage of them in Japan.
If you check out the Japanese version of his site, you will find only 2 links (that after 1 more click both lead to the same page) of kitchen knives - a set of 5 knives. The description is neutral, the kanji appears different:

On the main page Iwao Watanabe is mentioned as a smith, but it is not clear what knives does he make.
Rest of knives are outdoor knives and the origin is not clear - at least with the automatic English translation.
I personally do not care much who makes knives for Watanabe (as I do not care who makes Kochi line for Jon or who did StainLess Itinomonn line for Maksim) - I am just trying to get the message over, that Shinichi is not a knife maker, but a vendor.
