Scary scenario there. F Dick does have a lifetime warranty on defects and I'll wager that would fall into that.
From F Dick's web FAQ...
Is that plastic in the handle? I expect better for what they charge. Looks like this line right?
If you did get hurt, you'd have a great lawsuit.
I can't help but wonder what the rest of the story is. Seems like a lot of damage to the knife for just that little amount of corrosion or food crud (whichever it is) and slicing a roast beef... unless it got twisted between the ribs and the ribs were still on the cow.
Under maximum image magnification, it doesn't seem to have internal corrosion (i.e., "crevice corrosion), and the breakage looks clean and not jagged (although it appears that there was plenty of surface corrosion behind the bolster, right where the "scales" would siphon moisture, and it's difficult for the moisture to subsequently exit by evaporation).
My best guess is that there was a forging flaw.
BrianShaw (post #3) had it right
That's one type of knife design I will know in the future to not get.
I think you should send it to F. Dick under their warrantee program. But don't hold your breath in hopes of a good result. It still looks to me like a stress fracture... which may not result in them resolving the situation be in your favor. Are you sure that it wasn't accidentally "bent" some time before slicing that roast?
p.s. I'm very glad that you were not injured during the incident. A blade like that flailing around uncontrolled is a very dangerous situation.
