This may seem like a dumb question to some but what does this tool do? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=32718&item=3874774673&rd=1 Also, there is a tool which I don't know the name of it but I believe it has the purpose of cutting thin sheetmetal kind of like a scissor. They have one on monster garage and I think its pneumatic. The metal thats cut comes out in a thin strip and coils up. What is that tool called? looks handy. Thanks.
