It looks like Milwaukee’s willing to ship you a free sample of their Ice Edge blade in exchange for you turning over some personal information. There’s a “contact me in the future” box you can uncheck if you feel the need.
Thanks to Myself for the tip, who saw it on BensBargains.net.

Or, of course, you can just buy your own, starting at around $12 for a 5-pack.
