Either misinformed seller or a seller trying to misinform people.
Maybe it all has to do with semantics. Leave the blade out for the mild setting, put blade in for more aggressive?
I just saw a razor on ebay listed as a slim and fatboy (one razor, not multiple sale).
+1. And a slim that was called a FB.
Not uncommon for an uninformed eBayer to shoot high. If a "razor guy" had this listing, he would be branded "evil" . . . but electronics salvage . . . I'd cut him slack.
His feedback score says "buyer beware" . . . that scares me more than his erroneous description and high asking price!
I saw a gold ball-end tech listed on the bay for $49 ... US listing ... wonder if the sellers take any time to research "just what it is" that they are trying to sell ... and the average price rate.
