I was tool shoppin' at the local Proto dealer long ago. Come upon a 3/4 x 1/2 drive adapter. That would be very handy I thinks. Lots of BIG fasteners on rock farms and usually a substantial hike or climb away from the tool box. Take the 3/4 ratchet and adapter when I know 3/4 drive will be necessary. Salesman looks at is as he rings me up, " I want you to take note of the little warning there on the adapter." "This tool is not warrantied by Proto Tools" it says. He tells me "That is the only tool Proto does not warranty in their catalog." Okay, that means use common sense and NEVER loan it to the Rockheads :lol:
