Which weapon Mastery?

The Fighter's

Or

The Oracle's?

If it is the fighters, I see no problems with it. If it is the Oracle's, they do not stack (at least the improved critical part does not stack with the keen part) .

Keen

This ability can only be placed on a piercing or slashing weapon.

This ability doubles the threat range of a weapon. If you roll this property randomly for an inappropriate weapon, reroll. This benefit doesn't stack with any other effect that expands the threat range of a weapon (such as the keen edge spell or the Improved Critical feat).

Moderate transmutation; CL 10th; Craft Magic Arms and Armor, keen edge; Price +1 bonus.

---If you're talking about expanding the crit modifier than it should be possible. The rules are only in place to ensure that people don't further increase the crit threat range.

**Edit** Yeah...what Happler said.
