I thought the wire cutting its way through the ice by creating a high pressure zone at the bottom of the wire had been debunked and that it is heat conducted along the wire that does the melting.

Subject: [Phys-L] why ice is so slippery
Hi --
A seasonal and topical bit of condensed-matter physics.
Aimed at a general audience, but contains some hard numbers and makes a number of good points. Contains links to primary sources.
TL;DR: There's an ultra-thin surface layer that isn't really frozen.
