by "rare" i mean that i have not seen one listed on ebay in the last 18 months.
the term "rare" as applied to collectable knives has been discussed elsewhere(BRL, i think). if i recall correctly, there is no standard for this term, so i guess it is just subjective, but also overused by some ebay sellers for sure.
if a 171UH with birdshead pommel shows up soon, we're all going to be bidding against each other. i don't like this situation; preferred the old way, where you had the option of "giving a break" to a forum member.
