"No thank you, stupid idea if you ask me

Didn't think about blood splatter did you?"

"The blades, if made sharp enough, will require extremely large amounts of care due to the speed of the swing. You'll have to shut them down and go out to sharpen, clean, and replace blades every time they get used on an enemy, random animals that wander too close, etc.

If not sharp enough to cleanly slice through, the blades will shatter and rip themselves to shreds. It's pretty much guaranteed that any blade you could produce after the end will do this every time it touches something, but dull blades are more prone to it.

You can circumvent them by crawling.

Any questions?"

"Yeah I have one, why do you have to say any questions at the end of your post?

depending on the mass of the blade, and the speed of rotation, razor sharpness wouldn't be a necessity, and with proper edge treatment they could stay reasonably sharp for a good long time.

I'm not saying it's not a waste of a perfectly good motor, but if you could find an effective way to power them, then these aren't a terrible idea."

"What this project really comes down to is how badly do you want to scavenge for it? I mean **** If you want Indiana Jones type blades swinging to and fro, I can make them happen, provided the materials are at hand. You'd be amazed at how possible this sort of thing is provided there is a little knowledge and a whole lotta effort applied properly."
