About this 3D model

I really liked how buckyball's jigsaw blade handle felt in my hand, so I designed something similar for regular hacksaw blades (metal saw blades). The latter are thinner and longer than jigsaw blades and have smaller teeth usually. They achieve better results in specific cases, but they must be used with care so as not to bend them too much. Actually, it may be convenient to break or cut a blade to make it shorter (or recycle a broken one!).
