Perhaps get a more workhorse knife to wear for daily stuff. One without all the shiny bits, faux jewels and eating utensils. Even something like a KBar will look good and still have a functional purpose. Look at the dirks from the early and mid 18th century for ideas.
Something like these guys:

Im trying to get my hands on a now discontinued Cold Steel Culloden for daily wear- Its closer to sgian dubh size than dirk size but fills the purpose of having a more practical tool to really use for daily needs.
