Weapon Buffing Class / Archtype?

[AlcopopStar]

I had a lot of fun in 3.5 giving my friends bane or holy weapons with the artificer, I was wondering if there might be a pathfinder equivalent. Not so much for the crafting, but more the infusion style spells or abilities.

I really love the idea of spontaneous weapon buffing. (even adding flat elemental damage would be something).

Anything come to mind?

The closest that comes to mind is the dwarf forgemaster cleric archetype.
Instead of channel energy he gets the ability to inscribe runes on weapons and Armors.
In addition buff spells cast on weapons and armor have +1 CL and can apply a metamagic feat without level increase.
Sou you could habe a level 1 forgemaster whose 1r/level buffs last 4 rounds via extend spell.

Forgemaster is the only one that can do it for Allies.

Magus & Inquisitor can do it for their personal weapon(s) but not Allies...
