I sort them so if I ever do trades they're all done and being in the little bags is alot easier than trying to get a hook untangled from a 1000 in a box.
No mixed sizes - and I look for any bad ones when I sort them.
Yes I sort them by hand!!! I do piles of 5 each then into piles of 10, then 50 then 100. and bagged up. I traded Jim 50 ea of two sizes of hooks, so I had to sort some out anyway I just finished the whole batch. The small 4 mil zip bags make for easy storage without taking up alot of room in by box.
