I agree whole-heartedly with Bryan on this......think about those cheap and nasty, hard plastic handled screwdrivers that you find dumped in a box in every garage in the country owned by a less-than-skilled DIY'er. They'll have either snapped off, or chipped away around a central core of steel rod. OK, there's plenty of good-quality, plastic handled screwdrivers out there, but they use a grade of plastic that has a degree of 'plasticity' to help it flex and absorb impact. Corian ain't like that! Don't go there, Ryan!
