Rom owned a latinum-plated tooth sharpener as a child and the device held a strong sentimental value for him. (DS9: "Family Business") His son, Nog, held a similar attachment to his own tooth-sharpener and it was among the personal items that he auctioned off prior to his departure for Starfleet Academy where it was purchased by Worf. (DS9: "Little Green Men") Later that year, Worf's quarters were burgled. Among the items stolen was the tooth sharpener. This incident compelled him to request to live on the USS Defiant.
