Metal Earth is a company that makes small, but very detailed, modles out of metal. They have dozens of different subjects; cars, ships, tanks, spacecraft and even buildings. No scale is given, but this Tiger appears close to 1/72.
Construction is done by the "Tab A/Slot B" method. Some of the tools you will need are a sharp knife, a file, needlenose pliers and tweezers. Some of the parts are a bit hard to work, given their size, but it is not hard to assemble. It only took me a couple of hours to do. It looks cool and I'm sure I will build a lot more of these kits.
