The list author says: "A lot of people have asked me exactly which type of clamps and files I used to take the sharp edge off my MacBook Pro over on my tutorial page at: http://OneMansBlog.com/Macbook
Well, here is the list of items I used. You'll notice that I used Photography clamps which can be used for many other purposes too. But I've also included a couple of cheaper all-purpose clamps."
"The Manfrotto Super Clamps are the specific clamps I used in the tutorial video. They can also be used to mount remote flashes or fixed lighting for photography, and they are strong enough to bear a LOT of weight. These are some of the most versatile clamps I have ever seen."
"You can try these spring clamps. They are cheap, but pretty strong. You won't be able to push as hard as with clamps that tighten, but they might get the job done."
"THIS is what I really recommend you get! The whole matched set of files will be useful not only for filing the edge of the MacBook, but also for many other little projects around the house. These files will literally last a lifetime."
