More like a variant of the rolling hitch, like most slide and grip hitches are. To me the Blake's Hitch offers less purchase than the Midshipman's Hitch when tied onto the same sized cord. However I think it offers superior purchase when tied to bigger rope (like for ascending). I still like the Klemheist for ascening better tho, either way you still gotta have a loop and the Klemheist (and Prusik) are tied with a loop anyway.
