I've used them for 3 years now for turkey. They've proven to be the strongest mechanical (that's still in production) that I've used to date, as well as the easiest to change blades with. I've even shot them in the open position through blind netting with fantastic results (yes, they are designed to be shot that way if you wish). Get some; you won't be disappointed in them. Fuse Kusami are the same head too, by the way.
