hard plastic

Im looking for a real hard plastic that wont break easily under pressure. Use would be similar to a flat-head screwdriver/small tool- thats why the plastic has to be real hard. Metal wont do because it scratches. Can anybody help? Thanks.

Would HDPE be strong enough for what Im using it for? I think ABS would be way too soft.

Have you looked into high performance ceramics?

No, I’ll google it, but do you have a link?

hard does not mean strong.

“hard does not mean strong.”

I think that’s why the request also mentioned that the plastic can’t break under pressure. Hard and strong.
