A couple of queries about the Engineer's skillset and item possibilities.

Engineers are specifically listed as being able to create type-enhanced weaponry and items. Does 'items' refer specifically to the Silk Scarf/Black Glasses etc type of equipment?
I ask because my Engineer character has a specific interest in, possibly in future, dabbling in Enhancing clothing items, and I'm uncertain if this would collide with the standard 'held items' available or whether additional factors will be needed before he can try his hand at such things, if it's possible at all...
