Ya know, with the ARS, I had actual curved ones, I think back in 2004, then I was never able to find the curves, all I could find (Spare-Crime Willits) was the angled heads.
I didn't really care for the curved ones, but I'm weird, and there's a hell of a lot of trimmers who can put me to shame.
As for cleaning scissors, I cut the top one third off of a plastic water bottle, fill it enough with 99% (Or any strength ISO if all you're doing is cleaning scissors.) one or two (or three or four) pairs of scissors (ARS) will fit nicely in the opening, put just enough ISO to submerge the cutting edges, and keep a paper towel right next to it, so trimmers can swap out at will with one swipe on the paper towel to dry off the ISO & have a fresh pair of scissors. (I also like a little blast of 'pam' or any cooking oil in a can to lube the blades to get things started.
I've found this method to work (mostly) the best for larger jobs.
(don't over fill the cut water bottles with ISO, as it can sometimes tend to be top heavy, tip & spill.)
NOTE:
I never really had the time to worry much about scraping off the scissor hash, sometimes a trimmer would take it upon themselves to do so, but my main concern usually was getting flower in off the vine before the Northern California autumn's humidity (and mold spores) decided to take it off the vine for me through 'mycology'. (and thereby heading over my cliff)
