I believe you got some crappy pots. Sorry dude! What you want is multi-turn 10K rheostats. I prefer rheostats to pots for their size: pots tend to be small and thus a pain to adjust unless you love your miniature jewelers screwdrivers.

Also, some of what you see could be caused by dirty contacts. However that is probably not the case in your situation. If you scavenged an older rheostat, it could have dirt+grease buildup causing steady resistance that drops suddenly when the contact passes over the grease and then gets good (low resistance) contact.
