A grade item crafting question

Just a question that really troubles me. I have a WS 48 lvl and want to level him so he can craft A items. The recs for crafting A gear (including weapons) remain in the recipe book or are destroyed after the creation of an item?

to craft an A grade thing, your WS will need 2 recipes : one for your craft book (it will stay into your book, so you will need this one only 1 time), and one used for the craft (this one desappears with the craft, like others mats needed for the craft, and for each craft you will need a recipe).

This also happens to B items? What about SSA/BSSA?

for shots u only need one in ur recipe book and yeap same thing goes for b grade :)

for SS and Bsps of any grade, you just need the recipe into your book.

in most cases it makes more sense to just use the recipie on another dwarf
