The first step to building a plastic scale model is to remove parts from the parts tree. Rather than twist, snap, or slice parts free with a hobby knife, use micro-shears (also called sprue cutters) or a razor saw instead. Both of these tools allow you to remove the parts while minimizing the risk of damaging them. They also let you cut closer to the part, which means less time cleaning up with sanding pads or files. Watch the video to see how to use these tools to build your own scale models.
