Exacto Blades and Cooking Oil

As many of you know I always use Exacto blades to cut foam. I've noticed that this dulls the blade quickly, and I find myself changing blades often. Andrew Young of the blog Puppet Vision passed on this handy tip: if you lubricate your blade with just a tiny bit of regular cooking oil before cutting foam, it will take three or four times as long for the blade to get dull.

Thanks for the tip Andrew!
