Okay enough said about the Materials already.
As for the model (and don’t get me wrong, it does not look bad!), I think the Pliers edges are too muddy/rounded:

Also, the handles seem stuck together, also I don’t know how they should open and close because the upper handle connects to the upper plier. And I also don’t like the pointy ends, at least not how they are now (the points can never touch each other):

But still, not a bad job!
