During my 'Battle Damage Repair' course in the Army, we were told it was possible to saw up to 1 metre off the end of all 4 Lynx main rotor blades if they were damaged.
Knowing what I do about M/R track and balancing, you would have to be spot-on with the measuring of the saw line to prevent a massive unbalance.
Centrifugal pull of one Lynx M/R blade = 55 tons!!!!
