Welcome to the Yard Kwantum!
Your timing is great as the Dog Father Limited Edition is due to be released tomorrow! There should be an announcement tonight with a ball park time.
The Yard Keeper was only released in a Limited Edition model & was originally for Blade Show 2007. You can find them on the secondary market though.
Both blades are made of SR-77 steel. You can find info about the knife construction here:

Cheers,
Chris
