How are they compared to Elixir Nanoweb coated strings?
Both in terms of feel, tone, and in terms of how long they keep sounding fresh.
They seem to utilize a somewhat similar coating technique as the Elixir, in that the coating, unlike just about any other coated strings on the market, covers the whole string, but where Elixir utilizes a Cortex coating, which as far as I gathered is some sort of synthetic plastic/fabric, these Blacksmith strings seems to utilize some kind of Carbon based coating.
