My friends and I are planning on doing the knife edge on Katahdin in February or March. We've climbed tuckerman's ravine a few times in the winter and we have some winter experience on a few other mountains.
I've been trying to determine how technical the knife edge would be, but I can't find enough information. My biggest concern is the notch near the chimney. We only have general mountaineering axes and have never done any actual ice climbing. We'll be bringing a rope but what type of protection would we need, pitons or ice screws? Are technical axes needed for this route or will we be able to get by with what we have?
