I recently bought a single ice climbing screw to test it out, and I’ll be ordering 3 more without a doubt. I totally get that a $65 “ice stake” may sound like insanity, but if you are in a place where that doesn’t seem like a big deal, these things are freaking amazing.
You just put some pressure on it, and start screwing it in with your finger tips, and it digs into the ice faster and smoother than a wine opener into a cork.
And, yes, I’m well aware of all the drill adapters for conventional ice stakes (I own one of the Eskimos.) They work “fine” but it means you are switching out your auger and/or carrying two drills every time you want to drive a stake. These ice screws are just flat out better in every way (except cost.)
p.s. I won’t link a specific product just google “ice climbing screws” — i got the 16CM size black diamond from REI and $65 is the lowest price I can find online.
