This is an issue that I am happy with.
Think about those weapons of myth, Thor's Hammer, Excaliber, and so on. How many of them were forged by Wizards in towers? I'm thinking not too many.
Effects with huge penetration are only one way to get a superior weapon. They are IMHO the least efficient.
The simplest and IMHO most efficient way is to use the rules from City and Guild for weapons of exceptional quality. A legendary weapon smith (skill 9+) working with good materials in a good workshop with an assistant can generate items that provide huge bonuses, and aren't magical at all. Think about those weapons of myth, how many were created in this way? To my recolection darn near all of them. This option is open to Verditious. In fact a Verditious crafter gets bonuses to his lab total because of his crafting skill.
Another option is the items of quality mystery whereby a Verditious magus can use magic to bring forth the mundane qualities of the ideal form. Also not magical and also providing huge bonuses. I susspect that items of quality bonuses may be stackable with crafting bonuses for absurdly powerful weapons but I'd have to double check the rules.
A third option is to enchant effects that target the weilder rather than the tool. Inrtellego effects that give the weilder insight, muto corpus effects that give the weilder strength or speed, Muto mentem effects that give the weilder the mind of a killer, these are all unresisted. They don't conform to myths but they do make excellent story fodder.
Weapons blessed by the divine I see as provideing the protection of faith, the courage to do the right thing and perhaps a moment of inspiration for strikeing at the right time and place. The first two of these effects aren't resisted and the third can be constructed in such a way that it isn't either.
What myths do we loose? We loose the flameing blade of the Witch King as he enters Minas Tirith. We loose the sword +2 (giant slayer) from AD&D as a simple enchantment, instead it becomes a difficult tool to create and the product of master smiths and Wizards working together.
Do we loose anything else?
