Don't know how deep the cartouches are, but with Japanese swords it's common to sprinkle with talc or baby powder, lightly brush or shake it off to enhance the signature. Might (?) work for your blades???
Also maybe a pencil or charcoal rubbing on paper might be more readable than the original on the blade. Just a thought.
