You won't be able to break either, and if you do, it'll be replaced.

Edge retention is better w/ INFI, and it is less stain resistant. Toughness is very close - from what I understand.

That said, SR77's edge retention is still good. And it doesn't stain very easily if taken care of.

You can see the price difference if you take a look around.

Sometimes its nice to have the nice looking handles and logos and all that - but if you want a hard use knife that is comfortable to use (ResC on the scrappers is fantastic) at an affordable price, Scrapyard is as good as it gets.

One of the other guys will have a better explanation for you I'm sure.
