I bought these used Craftsman hose clamp pliers a little while back. I've been using them and they work fine. I was wondering if anyone out there could tell me approximately how old they are. There's no patent number or any real identifying marks on them. The handles just say "Craftsman" and show part number "9 4770." That's it. I checked the old Craftsman catalogs I could find on line, but had no luck finding them. I don't think they're particularly rare, but I was just wondering how old they might be. 60s? 70s? 80s? 90s? Your educated guesses are appreciated. Thanks.
