I will make sure to refrain from using oversized fonts for emphasis from now on. Also, if there was an aggressive tone in my writing, I sincerely apologize—it was likely because I wasn't in a calm state when I wrote it.
Now, to get to the main point: the pattern on the upper part of the chopsticks is undoubtedly a "frog." While there’s no written documentation to support this, in folkloric customs studied in ethnology, the frog motif is said to have been used by high-ranking women during the Joseon Dynasty (a medieval-to-early-modern Korean kingdom whose name means “Land of the Morning Calm”).
As for the deer, pine tree, clouds, and bullocho 불(不)로(老)초(草) (a mythical herb in East Asian legends said to grant immortality when consumed) carved into the jangdo (a traditional ornamental dagger), these are motifs inspired by the Sipjangsaeng—ten symbols of longevity—representing wishes for a long life.
Based on the patterns carved into the jangdo, it seems likely that this item was crafted with wishes for the longevity of a high-ranking woman in that society.
As a side note, the Joseon Dynasty was a strictly hierarchical society. For an ordinary commoner to wear a jangdo made entirely of silver—like the one in the photo—would have been extremely inappropriate, and potentially dangerous for their personal safety. If it had only partial silver components, it might have been overlooked. But carrying a jangdo made entirely of silver could be seen as a challenge to the class system itself.
That said, it's also said that there were countless people who—despite the risks—boldly displayed such bravado.
Men would wear the jangdo at their waist, attaching it with a traditional knot, while women adorned themselves with it by hanging it from a decorative tassel accessory called a norigae.
The uploaded photo shows an example where I attached asilk knot I purchased to a silver jangdo crafted by a Korean Master Artisan officially designated as an Intangible Cultural Heritage holder (a title awarded by the government to those who preserve traditional crafts). The decorative fittings are made of silver, while the scabbard and handle are crafted from ebony. The person wearing it at the waist is a friend of mine.
I’ll tell you about the blade itself another time—based on what I know.
