When I was looking up Sims4 custom content and conversions I found Srsly's Wall Swords and found the scythe there in particular pretty interesting as a wall sculpture and knew I wanted to do my own set of scythes to go with the one in that package. After a bit I knew I wanted to do Grim Reaper conversions so I hung onto their scythes when I gathered my asserts. After all - you never get the Reaper to have his scythe once he joins his household. So where does it go? On his wall! A memento from his days of active duty.
They're all there. The Sims1, Sims1 console, the Sims2, Sims3 and the one in Sims4. And the trident from when the Grim Reaper's underwater in Sims3 too - why not? Why include the Console Reaper's rather out of place scythe? Well, like that bit of CC it's mainly for completion. And the Sims Freeplay's Reaper actually doesn't own a scythe - he uses a book.
Have fun!
