I know that weapons can be re-forged to make 100% elemental damage weapons using the exquisite of quality option and I have seen people have a lot of success with using dull copper / shadow hammers.  I wanted to know if anybody has had any luck using oak saws.  I prefer using a macer as my sampire and I like the black staff but I burnt through like 150 charges on oak and only got 1 weapon that was even useable and it was only 70% fire damage.  When using saws it is necessary to use ash saws?  That could get very expensive.
