Has anyone exerimented with the nylon replacement blades for string
trimmers? I just got one for my trimmer. It's a wheel with 3 pivoting
nylon blades, each about 4 inches long. They are light weight and might be
safer than a metal blade. I'll try it on grass and let everyone know how it
works.

I think that's why the Weed Eater robotic mower uses the spinning disk with
exacto knife blades. They are light weight and it gives some flywheel
action for low power consumption.
