A couple upgrades

[Rayse Valentino]

What's the highest I can upgrade my steel knife, Kapteyn, and my Damascus longsword?

edit: I have been informed that the highest material is Prevaldia. Can I get a price check on that?

[Revenant]

Prevaldia Kapteyn (with Magicite Enchantment): 3000 gp
Prevaldia Longsword (with Moderate Concussive and Light Burn Damage Enchantment): 2700 gp

Total: 5700 gp
