On topic because they're old enough (30+ years?) to have wood handles and trimming hedges is working with "wood", just on a different scale ;-)
My better half was out trimming some flowering bushes and brought the shears to me when they "came apart". I'm almost certain the shears had a "finger" washer that provided tension on the blades and served as a lock washer as there's a circle worn in the blade that's a little more than 1/8" larger in diameter than the nut. I used the small metal detector (usually used to find dropped hardware in grass) to search where she'd been working but the only "hit" was part of a metal foil candy wrapper :-(
Anyone have a source for parts that old? Sears Parts online has nothing; not even a diagram or parts list. Searches for "Craftsman
8605 hedge shears" and similar do find some on Ebay but new Fiskars in the same size and with a similar compound cutting action are lighter and cheaper ($27 at HD).The better half got the new Fiskars to finish what she'd been working on but I'd like to get the old shears operational just to have a backup and maybe be able to tell the grandkids "They just don't make things like they used to" ;-)
