Sleepless in Seattle wrote a review of Black Diamond Lost Arrow Pitons - DO NOT USE on June 23, 2006
What can I say? They're pitons. I hear they are ugly, but I don't use them on mountains. My climbing is in underwater caves, and pitons are the only secure way of "climbing" down against the flow of a 1st-magnitude spring. They hold well over time. I only wish I could get them in stainless-steel.
