I had an idea about jeweler's being able to engrave words onto jewelry and thought that they should also have the ability to engrave forger's blades and other weapons. It wouldn't be much of a change and wouldn't really affect anything too much but it would still be an extra little thing to make jewelry and weapon using more interesting. Still, this is just an idea.

Can't they already?

Whaaa...... t-t-they can??

I remember seeing a dagger engraved, though I might be mistaken..

Pretty damn sure you can, armour and jewellry alike.

then may this post be deleted and forgotten. My bad.
