I always use an Olfa knife for things like foam core. X-acto blades and
knifes I use only for small delicate curvy complex cuts in thin material
like paper.

Olfa knives come in two size and have break-off blades:
1) OLFA Standard Cutter 300 (see
http://www.utrechtart.com/dsp_view_product.cfm?item=83056) and 2)   2) Olfa
Heavy Duty Snap Off Retractable Knife (
http://www.utrechtart.com/dsp_view_product.cfm?item=41524) The good thing
about these is that you simply snap off the used blade to get a new sharp
one.

They're great for straight line cuts (with a good metal straight edge) and
generous arcs.
