I have experienced a lot of different tools on my feet from lers trying to tickle me (unsuccessfully so far) over the years.
Usually it just fingers, feathers, soft or firm bristled brushes, electric toothbrushes. Lotion is often thrown in the mix. Teeth and tongue (which I am not personally a fan of on the feet as it feels gross to me).
Sometimes you get less common things used like grooming gloves, hair, toe nails (people trying to tickle you with their toes), pin wheels, flossers, guitar picks, items that have massaging or vibrating heads, pens and probably other things I forget.
The oddest or most unusual I would say are people trying to "paddle" your feet to make them more ticklish or the violet wand. Both of these can be a bit ouch, so I am not really sure how thse are meant to tickle someone.
I always find it kinda funny and interesting what things some people pull out of their "tickle tool box" to try and get me with. It's also kinda satisfying to see them get to the bottom of said tool box and have to admit defeat (sassy time!).
As a tickler I generally just prefer to use fingers, mouth and lotion, to me that's more intermit, fun and usually more successful. But I can appreciate tools also have there place and use.
