today is a day of hmmmm. cleaned up the Wrought Iron bar  and looked at the L6 and 1080 . How am I going to stack this the 1080 and L6 is 0.04" the wrought Iron is 0.1"  so I see two patterns
1) WI,,L6,1080,L6
2)WI, 1080,L6 1080
Pattern one will be more flashy with less carbon migration.
Pattern two will be more subtle and will have more carbon migration.
as this is the body of the knife carbon migration is not really an issue. 
time to sleep on it.
