I'm a big fan of this "Just watch me do this thing, the video speaks for itself" style of youtube. No animations, product placement, voice overs. No stupid jokes!
slicing a cucumber is a common feature of youtube videos demonstrating how sharp knives are. (I spent a completely unreasonable amount of time watching knife sharpening videos on youtube a couple months ago)
From my own experience slicing slightly overripe tomatoes that have some give to them are much harder to slice with a non serrated knife than a firm cucumber. Wonder why cucumbers became the standard haha.
