I recently did some research for a couple of knives I'd like to buy to replace the one I have at home, and I've almost decided for the Wusthof classic. I also found those very affordable knives here: http://www.knivesandtools.co.uk/en/pt/-eden-classic-damast-3-piece-knife-set.htm#tabbutton3  They look very well made, and I found few reviews, all positive. I wonder if someone of you possesses those and if a comparison to Henckels / Wusthof can be made. 
The ingredient is Mizuame (水飴), a Japanese sweetener. It adds sweetness and gives a luster.  When they need large amount, professional cooks usually scoops it with their bare hands, as she does in the movie.  I'm not sure of the reason, but Mizuame is very sticky and it is troublesome to handle with tools.  And this behavior explains that she has long experiences in making read bean paste.
