Although opinions, as usual, do differ. Gear guru Andy Kirkpatrick in the same discussion says, when comparing ice hooks to warthogs that "a warthog will rotate under load, or bend, then pull out, were as a hook has to be pulled through the mass of turf."

The Warthog ice screw had been unavailable for some time but not anymore as Needle Sports, the independent climbing shop in Keswick has started to have them manufactured and distributed.
At the Needlesports website www.needlesports.com, owner Stephen Reid writes:
"The Warthog Ice Screw was first made by Salewa but as far as we can ascertain, Mountain Technology were the only company that have produced them in recent years. With the demise of Mountain Technology, and their parent company HB, the Warthog, so beloved of British and Polish climbers but so little known elsewhere, looked like becoming an endangered species. However, Needle Sports has located the engineering firm that originally made Warthogs for Mountain Technology and are very pleased to be able to offer them once again. "
