Seen this on eBay, not possible for me to bid on it. Looks to be a Japanese model, riveted, no USA on the pliers and can just make out leatherman Japan on the blade. Seller doesn't know what they have judging by the price, hope someone on here gets it http://www.ebay.com/itm/Retired-Vintage-Leatherman-PST-Personal-Survival-Pocket-Multi-Tool-Pliers-Knife-/251309827908?pt=LH_DefaultDomain_0&hash=item3a833ba744&autorefresh=true
