This has got to be the smartest idea I've seen in awhile.  There is no pressure on your hands while using them.  The only thing I had to do on occasion was blow them off.  I was cutting a kink size rag quilt and the fibers/dust kept getting in the blades and that bogged down the spring action of the handles, but a quick blast from the air compressor and they were good to go.  I had to do this three times for that king size quilt.  Still the best idea.  It saved my hand from having to use regular scissors to cut that huge quilt.
