I bought a roto-zip tool this summer, damn that is one scary piece of equipment

do you mean a rotory tool (dremel to name a brand name?)

I love my rotory tool-- I bought one each for my son and daughter... and they love them too.

they are so versital-- i bought a set of small wire shelves to put under my bathroom sink (is an oldfashion, wall hung basis(lav) no cabinat underneath.

the shelves were 1 inch too tall.. out came the rotory tool and a cutting bit, and Voila! they fit perfect now.

an other bit was perfect for making the 'round' mortices in the doors (from the old hardware) into rectangles with rounded corners (new hardware!)
the are also great for makeing fine routed grooves on the underside of shelves to run low voltage wires (from the black light say) to the outlet. And then the rocks that florese can glow in UV light..

my daughter uses her's for work on her doll house.

my son finds it to be an all purpose tool for an apartment dweller--he does little things. (day one, (christmas a few years back) he couldn't wait to try it out.. now his step son has name and info 'engraved' on bike, safety helmet, skateboard, pogo stitch,... any thing that didn't move!)
