This weapon would likely be infinitely useful to a guy with the Underhanded talent:
This weapon consists of a small metal tube hidden within a sleeve; the tube holds a short, spring-loaded bamboo shaft. You gain a +2 bonus on Sleight of Hand checks made to conceal a tube arrow shooter on your body. Releasing the fastener allows the spring to force the arrow out. Once a shaft is fired, the tube must be reloaded before it can be used again. Reloading a tube is a full-round action, or a standard action if the wielder has the Rapid Reload feat.
And as far as drawing a weapon and attacking with it in the surprise round:
Ambush (Ex): At 4th level, a bandit becomes fully practiced in the art of ambushing. When she acts in the surprise round, she can take a move action, standard action, and swift action during the surprise round, not just a move or standard action. This ability replaces uncanny dodge.
These supple leather sandals grant a burst of speed during times of duress. When the wearer acts during a surprise round, he can take a standard and a move action during the surprise round. If the wearer already has the ability to take a standard and a move action during the surprise round, he instead gains a +10 circumstance bonus to speed when acting during a surprise round.

This item works like a standard wrist sheath, but releasing an item from it is an swift action. Preparing the sheath for this use requires cranking the sheath’s tiny gears and springs into place (a full-round action that provokes an attack of opportunity).
Almost forgot this little gem:
You can charm people into lowering their defenses, allowing you to ambush them more effectively.
Prerequisites: Quick Draw, Persuasive, base attack bonus +3.
Benefit: When you succeed at a Diplomacy check to change a creature's attitude, you can draw a weapon and make a single melee attack against that creature as an immediate action. If you changed your target's attitude to friendly or better, your target is considered flat-footed against this attack. If the target survives, it takes a –2 penalty on its initiative check for this combat.
Once you attack a creature, its attitude becomes hostile.

It is said that this question was answered in FAQ, but cannot find it under the Ultimate Combat topic at FAQ.
My real concern is whether it is officially accepted that you can conceal a weapon with Deft Palm without placing it somewhere on your person, so doesn't force you to spend an action while drawing it.

Since I didn't see it mentioned, if you have an accomplice to help you, there is the Lookout feat:
If both you and your ally would be able to act in the surprise round without the aid of this feat, you may take both a standard and a move action (or a full-round action) during the surprise round.
I know people love to hate on Teamwork feats, but right there is another way to get a full-round action during a surprise round.
We're getting pretty feat intensive, as now we need Quick Draw and Lookout, and a friend with Lookout, but it allows one to draw a concealed weapon as a move and stab as a standard all in one surprise round.
If your friend is a cavalier, he could loan you the Lookout feat for your stabbing needs. Giving your whole party Lookout is a solid pre-ambush play.
