I was slightly annoyed by the whole rigmarole about the angle as well. Silly of course because everybody should use the angle that suits them best. It's just that when I was taught 'hammering' as a kid, it was drilled into my head that I should always have the pivot point of the arc level with the thing I was hammering. So if you hammer from your wrist your wrist should be level with the impact point, and if swinging from the elbow the elbow should be there.

I couldn't stand angled mallets, because if you want to strike something on a flat surface you'll have to put your wrist awkwardly close to the surface.

Also, in the webpage he holds the mallet more than halfway up the handle, wasting the bottom half. I was similarly drilled to always hold it at the end of the handle to maximize the length.

And then I'm slightly annoyed because he confuses flaired and flared.

All in all a very nice website, where I can be comfortably annoyed by nice niche nerdy topics. A blast from the past in between the onslaught of AI related content ;-P
