Unfortunately blueprints are not based off grimoire. The items had to be in your inventory or vault when patch 2.0 went live on September 8, 2015 to provide a blueprint. Anything dismantled prior to this would need to be rediscovered.

So where else will my gear be other than in my vault or my inventory?

If it was dismantled
-
I get that if it got dismantled it shouldnt be there, but I have them in my vault and inventory, yet no blueprint. Like my Thorn, which I worked for, my ice breaker and not to mention ghally.

You have the item in your inventory or vault now and you don't have a blueprint still? Make sure you're looking under the year 1 blueprints. Those weapons you listed do not have year 2 versions yet.
-
I was and I so sorry for not realizing that they were not available as of yet in year two.
-
As the 3 weapons you mentioned do not have a year 2 version currently available, I have to ask, are you looking for them in the year 2 section, or year one?
