So a thought occurred to me, how does crafting items work for a caster with multiple caster levels?
Let's say a caster with wizard 3/cleric 3 with Magical Knack that boosts wizard up to 5. Since he has caster level 5 he can take Craft Wand for wizard spells without trouble. Can he also craft wands for cleric spells too or does he need a caster level of cleric 5?
If you have the feat, you can craft the wands. For instance, if you took a completely new class next level that gave you 1st-level spells, you'd be able to craft a wand with those spells, though only as a 1st-level caster, barring an ability that raises it. Whereas a 1st-level wizard spell in a wand could be up to CL 5 if you wish and a cleric spell in a wand could be up to 3rd.
