I............love............eBay. This lot would have cost close to $100 at the craft store. I got it on eBay for less than $25. With all these blades, perhaps I can be less stingy in changing the blades to my X-acto knife.
Oh, which reminds me. This is one of the very interesting uses for corn when crafting:
One of the hard kernels is just the right size to use as a spacer when your retractable X-acto knife no longer retracts. (Is that "thinking outside the box" or just plain being cheap?)
