Yeah, that's one of the difficulties. That's probably why the Guinsu knives people ended up having those demonstrations where they cut bricks, metal, etc., to capture the customer's attention quickly. I would not personally go that far though!

Oh, for sure! That kind of display is wildly effective but unfortunately misleading. Part of the problem is that a great knife will cut a carrot, a garbage knife will cut a carrot, a house key will cut a carrot. Displaying their abilities isn't easily captured in media. I'll work on it.

There's ways you can show it without it being stupid. For inspiration, have a look at the following:

The what you want to get across is the effortlessness of cutting with a really sharp knife made with VG10 or similar Japanese carbon steel, vs what you're going to get out of a more traditional German or French knife with something like X50CrMoV15 or similar stainless.

A good video explaining what's going on with the differences between knives would probably help a lot.
