The piston ring speed on the average chainsaw travels 2,500 surface feet per minute. A chain slides across the surface of the sawbar rail at around 5000 feet per minute. The chain is moving at 55 to 60 m.p.h. or a mile per minute (88 feet per second).
The theif that tried to cut my chain probly used much larger bolt cutters than I had. The hacksaw blunted instatly when I tried to cut the chain with it. The hammer and spike also did barely anything to the chain. The lock's 16mm shackle I couldn't even grab with the small bolt cutters.
