Given the leftmost one is a warthog, surprised you can let go of it?
Actually it may be the most useful one if you're a south coast chalk climber (I'm serious)
The warthog AFAIK is basically an ice screw without the screw; it's an old hammer-in style. I think they were also supposed to be quite good in frozen turf? (where you obviously wouldn't want to use a screw)
