Elecetroplated shredder blades

So i’ve been wondering if you made the shredder blades out of concrete or wood, then covered them in conductive material (either via conductive paint or sputtering), then electroplated the pieces, would they be strong enough for use? any help would be appreciated!

@calebmadden. Only steel is strong enough for shedding plastic. You could try other materials but I am certain you will be disappointed. Epoxy or fiberglass could be used to strengthen the materials you suggested but in the end the time, effort and money would still allow steel to win in the end. Sputtering or conductive paint are for conductivity, reflection or cosmetic applications their strengthening values are almost nil.

Overall metal is the cheapest option, by far. glass fiber could maby be used, but it is significantly more expensive than steel, and more difficult to work with.
