Yeah I thought he had gummed up a fine tooth metal blade the way it was cutting, but that was a carbide thick metal blade. Still had melted aluminum on it, but plenty of cutting left in it.

Dunno if he was intentionally doing it wrong but the shoe definitely needs to be kept up against the material of at all possible. (You know, unless you’re demoing out a residential door frame or something that needs a little room to breath)
