Cooking Knife junk result?

I got a Cooking Knife from Blessed Magic Powder, Thunder Crystal (RF, 1 Charge), and Fireball Crystal (RF, 5 Charge), now that sounds like a junk recipe to me, I'll try me and see if I can't reproduce the results. Also the stats did not gain or loss any points.

Edit 1

I just got a Ladle from the same recipe, however I just thought of this, the Blessed Magic Powder was acquired through synthesis when I used it to get the Cooking Knife and I bought it during these experiments, I'm not sure if that will affect the outcome. I'm also unsure as to the origin of the crystals as a friend gave them to me.
