Actually, Amsteel is weakened by severe bends just like any other cord. The difference between natural fiber ropes and synthetic fiber ropes is the slickness of the fiber. Fibers like Amsteel will pull a knot tighter than a similar knot in a natural fiber due to the lack of friction on the line. Hence increasing the bend radius in the knot. Knots actually derate synthetic fibers more than natural fibers due to this reason.
