Just noticed this one on eBay:http://www.ebay.com/itm/331911383189$250 B-I-N for an early SOG ToolClip !!!!I know they aren't seen for sale that often these days, but $250 seems quite optimistic to me.
Apparently if you put RARE and DISCONTINUED in the title line, you can get ask a lot more money for it!
$110 for an early Kant Slip pliers. http://www.ebay.com/itm/262551473126
