Jay Fisher has all his patterns online for anyone to see:

KN Member D. Comeau from Canada has a fantastic website with a lot of patterns.
He is a great guy and helped me when I first started looking for patterns:

There are many others out there but with these two knifemaker's, there are more
patterns on their sites than you could build.
Good luck and hope this helps,
