Here's that variant of a Kelvin #necktie #knot with the wide end put through two loops at the end. It turns out after reading The 85 Ways to Tie a Tie, that this also has a name: "Diagonal".

Searching the web it seems though that the name has now been taken over by the novelty knot I tried here: https://mastodon.sdf.org/@bkhl/102918599821834593

I was a bit positive about that one that morning, but it didn't keep its shape well, so I didn't use it again.

I might try it sometime with a tie with more friction, though.
