Screw myself
I have a set of screwdrivers with handles shaped to fit a hand comfortably. Some parts larger around than others. Using them is great. The variation in sizes is very apparent if you tighten yourself around it.
Get hammered
I like the standard hammer from the tool box. I lay the heavy end on a bed of pillows or on the floor, with the long handle sticking straight up. Then I slide myself down on it, and rock and ride with the fantasies flying. It's awesome!! It goes nice and deep, and the girth is perfect.
Screw it
When I get really horny I use the handle of a huge screwdriver and slide it in and out of my pussy using my middle finger to rub my clit. It works great.
All shook up
I like to use a cordless vibrating power sander without the sandpaper on.
