Sturdy
The ball bearings make them roll smooth. I've put plenty of pressure through them and no bending or breaking. The middle sized unit is probably the most useful. The small one has it's uses but can act like a pizza cutter and easily go through sound deadening mats. The large one has a little too much surface area to get a good crush on the mats.

Works great, good price
Makes installing sound deadening panels a breeze. A little elbow grease required but makes for perfect contact with the sheet metal and butyl.

Well Made Tools!
I have been installing Kilmat in my early 74 Datsun 260Z restoration and these tools are very nice for the price. I like them because they actually have ball bearings and move smoothly over the matting. The size selection is very handy as well and even has some nice finished wooden handles.

Must have
These things a freaking AWESOME! If you're doing a big sound deadner job, you need thees! The 3 different sizes are perfect for the different shapes in the floor pans. Well built, good quality and they have a nice weight to them. Just buy them and thank me later. For $15.00 you can't go wrong.
