I was about to buy some but I hated that they were talking about an awesome "stretch cut" which simply sounded rediculous. If my knife is stretching the meat before it cuts its a problem not a feature. Turns out that the dull part of the blade blocks half of the sharp part.
I read some tests that rated it below my cheapo shwackers. That and the price of $18 a head (15.00 + shipping) I said no.
Let us know if you like the head you get! I keep hearing great things from magazines etc.
