I don't use mine often -- it makes me feel like I'm cheating on my straights -- but don't think for a moment that they aren't great shavers.
If you decide to give it a try, just strop that new blade, don't try the hone at first, it probably doesn't need it. Pay attention to how it's packed, and never force the lid closed -- that's how these end up with cracked hones.
They're not really valuable, still very plentiful -- why not give it a whirl?
