Detachable Sleeve of Endless Daggers
Powerful Conjuration; CL1st Slot; None (although they are worn on the arms)
this long detachable sleeve can change it's appearance to match whatever garment is worn, when the sleeve is reached into (as a free action) allows one to draw a masterwork dagger that dissapears once used for a single melee or ranged attack. the sleeve may produce an endless supply of these daggers. and the daggers produced dissapear after one round if not used.
variant Detachable Sleeves of Endless daggers might pass magic weapon enhancements on the daggers they create. the price of the enhancements is added to the price of each individual sleeve that bears the property.
similar items may exist for variants such as a quiver of endless arrows, a magazine of endless bolts or bullets, a glove of endless javelins, a sling that produces infinite sling stones, or any ranged weapon ammunition really.

Market Price. 8,000 gold pieces (4,000 to craft). adding enhancements to the sleeve requires an additional cost equivalent to enhancing a magic weapon.
I'd probably just make it bracers, personally. I had a player request it years back to replicate Jarlaxle's (drow from Salvator's books) bracers.
Bracer or just a dagger sheath that they can strap wherever they want.
