[TheForge] Damascus warpage and blade rivets

[Daniel Kretchmar]

Curiousity,
1.    Several of the last few blades I have done have warped during the the
hardening process.  I have attached the steps below.  What am I doing wrong?
2. Anyone know where I can get the 2 part copper/brass rivets that have end
up having flat heads on booth sides of the knife handle?  I think one fits
inside the other.
