Nice job on your pens with the glued up segments.
Not to be a stickler, but it seems we throw different words around and sometimes not very accurately.
Here is the definition of lamination :
Merriam-Webster's Medical Dictionary, © 2002 Merriam-Webster, Inc.
lamination
n 1: a layered structure 2: bonding thin sheets together
I realize everything is relative and my definition of thin may not be the same as yours.
I had done a lot of surfing while coming up with ideas for pens and when I don't look up the right word I don't find the information I want.
I would say your pens would be diagonal segments.
Beautiful combinations nonetheless.
