My first impression is that they're a little large and would be difficult to get into any tight keyways. I haven't gone through the templates to compare the size to other designs but I'll update the post when I do.
Behind the King and Queen are the Bogota Pi's from SEREPick. They're titanium and I really like them for EDC if that's your thing - having the hook is really nice vs. standard Bogotas at least for me. The tension wrench is not great but it's flat and works well enough for the common things you might run into.
