Is my Animated Knife (Construct, Diminutive) too strong?

[Minty88]

Oh, I did not realize that they didn't get feats or skill points is that a feature for all constructs or just animated objects?

EDIT: Oh, its the intelligence score that does it. My bad.

Numbers it is then and the touch attack I forgot about too. I chose 40 ft flying specifically and 4 HD because I want them to figure out how I want them beat or figure out another creative way to do it.

Oh, I don't think I want the to have a hardness score because I don't want it to be TOO hard if they go with the direct approach.

Their master is a passive foe and he cast permanancy on the kitchenware.
