Don't get me wrong, I love seeing all sorts of knives in action, but after seeing a lot of good videos (Salty's grind series), Jon's informative product videos, and even still photos of Colin's pass-around feedback, I was thinking about what some of the 'best' qualities were for videos.
Here are some things I like in videos:
(1) Comparisons to other knives. Cutting through an onion or tomato is fine with one knife, but comparing it to another knife makes the point better. I don't mind the videos of freakishly sharp knives, but they aren't my favorite.
(2) Including information/video about food release and wedging is always interesting to me.
(3) And I always feel I am learning something with Jon's videos. So I guess education is always good.
