I think historically such a type of weapon did exist.
In the realms of Golarion the Cinder Lands barbarians have a device that is also similar to what you have described.
I believe it is known as a 'Klar'.
Basically a large, treated animal skull (Some 'civilized' copies use a metal buckler) with a dagger projecting forwards.
So, damage is as a dagger; 1D4, crit 20/X2 that addsa +1 to AC.
Hope this information helps as a comparison.

I've created a new weapon, a punching dagger/s.s.shield.
when used in pairs (+3 defending p.dagger/+3 bashing s.s.shield) that would be 4 weapons, right?
EDIT: Ninja'd.
Sounds like you want a spiked shield (or two?). I really don't understand your post.
A +3 spiked steel shield does not gain the +3 on attacks and damage rolls, even if used for bashing. The Bashing property gives bonuses for such, but flat enhancement bonuses do not.

The wording in my post may not have been clear.
The 'Klar' is written as being a 'big' or 'large' animal skull. When more 'civilized' people try and recreate the 'Klar', since they probably do not have such easy access to large animal skulls, they replace this with metal. hence the wording of steel shield.
Game mechanics wise, the stats have a +1 AC bonus, hence my use of the term 'buckler'.
Damage wise the item does 1D4 Damage.
Yes, the Dagger projects from the edge of the shield, hence with the appropriate feats the user can attack AND retain their bonus to AC.
I apologize for misreading your post Sowde Da'aro.
Since your wording brought to my mind such a device.
Adding a spike to the 'face' of a shield, even with bashing...?
Sorry, adding a Dagger to the face of a shield? This is already covered in the rules as written (R.A.W) and I don't think it can work the way you seem to be describing it.

well, i had no problim with your post ("), but with foghammers...
trying to explane things in writen form is not my forte.
anyway, no dagger on the Face of the shield, but i was thinking about a sharpened outer edge... and a spike at the elbow...
i had the thought of a WIRILING dervish rushing about the battlefield...
YES!!! Tim4488 that is exactly what i was thinking

Thank you Abraham spalding for the correct spelling.
As for damage etc, again.
+1 to AC bonus, it's small buckler.
1D4 Damage, It's a dagger.
If the character wants to both attack AND keep their AC bonus, then I believe they need the feat "Improved Shield Bash". Other wise, they can use the shield to defend and when they make an attack with the dagger they lose the AC bonus.
On the K'lar note, I have also seen art work of a wizard or sorcerer character who has a K'lar type weapon that leaves their hand free. Thus, for all of the appropriate feats, the caster can have a weapon that is always ready, cannot really be disarmed, adds to their AC and does not hinder their casting.
To use such an item, I think the Katar is an exotic weapon.
Gaining the attack with the Katar blade while keeping the shield bonus would seem to require the feat "Improved Shield bash"
Though I do believe the Katar does 1D6 damage?

In the Golarion Campaign Setting the K'lar is listed in both the Weapon and Armor sections. (Pages 209 & 210)
I assume since it does both...
So, as I've written before, minimum would be "Improved Shield Bash" feat to allow the character to attack AND retain the AC bonus.
Other than that? With a DM whose happy with the thing and that one Feat you should be set. =)

p. dagger is a simple weapon. in the Pathfinder P.G.
Dagger, punching 2 gp (sm)1d3 (med)1d4 ×3 — 1 lb.what other kind of feats should i get?
If you wanted to use two at the same time, you should get two-weapon fighting and it's follow-ups. That's basically it. 3.x and Pathfinder doesn't very well support the whirling, mobile two-weapon-fighter; if you're going to dual wield, you'll have to be pretty stationary to get your full attacks.

Fighter Mobile archtype does it well enough (imo) while the two weapon fighter archtype does it *some* at level 9.
Another option would be beast totem barbarian 10 for pounce.
As for the weapon you are creating itself:
It falls flat on several different points:
First -- it doesn't match what's already available (and you don't need the campaign guide since everything in it *mechanically speaking* is for free on http://www.d20pfsrd.com). Also it violates the "light shield means no weapon" clause. However I can see overlooking that for a specific weapon.
However it also ignores the "one attack form per limb" rule. As such I would recommend the following:
Weapon Stats:
Biggered K'lar(exotic weapon) -- 1d4(Piercing x3 critcal)/1d4(slashing bludgeoning x2critical) double weapon
When used as a one handed weapon the Biggered K'lar gives you a +1 shield bonus. This may be improved with shield focus and greater shield focus. When used as a double weapon you lose this bonus unless you have improved shield bash feat.
Then the following feat:
Super Biggered K'lar Fighting(Combat Feat)
Prerequisites: Exotic weapon proficiency(biggered K'lar), two weapon fighting, improved shield bash, shield focus, weapon focus(biggered K'lar)
Benefits: When two weapon fighting with two biggered k'lars you may make an additional shield bash attack when full attacking. This additional shield bash is in addition to the attacks you make with the biggered k'lars, however all attacks you make this round suffer an additional -2 penalty to hit. In addition the shield bonus you gain from one of the biggered k'lars is increased by +2.
