A lot of the metals ones are class 9 which is about as good as it gets. Butchers don’t use many pointy blades. They are puncture proof. The test for puncture proof is drop scimitar point knife from 1 foot and see if it penetrates. A 9 requires 6000 grams of pressure to cut through material. A 6 is 3000 grams. Kevlar doesnt provide those levels but works fine in ordinary kitchen for heavier tasks. Its a 2 btw.
I will definitely keep all of that in mind :-)
