I mentioned it in another thread somewhere else that these were quite popular at my first fire department, so, wanted to be on of the cool kids, I bought and carried one for about a year. While I can appreciate the utility I never found out why they were so popular - they just didn't do it for me. I attached my SAK Classic to the little ball chain and used it more than I ever did the Christy Knife. Mine has long been lost to history (or my ex-wife).
