I have a set of the Pika hooks. They were only available for a short while and I was way too cheap to buy them but then won a set in a raffle at Neptunes. Three sizes. Two orientations. The hook end was twisted to either sit along a small edge, or left straight to fit into a thin crack, hole or pocket.
Hot-Parad-Ice, Kingfisher. Large Pika Hook. BOMBER!
Th Fish Hooks look burly, but maybe a tad heavy for how much use they get?
I have an Ibis hook, similar to yours Crusher, that a tradesman in SLC made for me. I found a smaller hook of similar design, though lacking the stabilizing lateral fins in a slot in UT. Great tool for technical canyons or sketchy solo explorations where a drill kit is too heavy or uncool or whatever. I understand that these are most often utilized in upward progression but I most commonly employ them as a janky and retreivable 'anchor' for descent. I also use them to back up meat belays in canyons quite often. Wonderful tools methinks. It is always a tad awkward though, to lead with one on the harness. They are essentially giant meathooks after all. I keep my big one sheathed in an old webbing sleeve to ease my mind.
