Utúlie'n aurë/Auta i lómë

Nerdanel has some type of genetic chronic illness, I haven't decided exactly what yet. Her cane has metalwork decoration, and a locking hinge mechanism to allow it to fold, because one of my canes is folding and it's super useful. Those parts were made by Mahtan. The Fëanorian star carving and crystal section were later modifications, and I think Nerdanel would continue modifying it throughout her life.

I've drawn Idril with prosthetic legs post-Helcaraxë, and some people with prosthetics use canes or other mobility aids for extra balance. I also headcanon that her silver legs were made by Celebrimbor once he ended up in Gondolin, so before that she may have had lower quality prosthetics and relied more on a cane. Hers has an eagle carved into it (Thorondor maybe), as well as eagle feathers, ribbons, and her heraldry for decoration. Elenwë's name is also carved closer to the base as a memorial (hopefully I did the tengwar right).

Celebrían uses a cane in Valinor due to her injuries. Hers is mallorn wood with metal decorations. Specifically the snake and flowers reference the House of Finarfin. The snake is made of mithril, which i think would be popular for mobility aid details due to its light weight. Also, she got Celebrimbor to help her make it after she dragged him out of Mandos.

Elros' is the only one without a wrist strap because I unfortunately couldn't work it into the design well. He uses it due to a leg injury from the War of Wrath, mostly because I wanted Elrond to encourage him about it in a fic I never finished. The handle is a carved and painted seagull, the column shows fish, and the base has Eärendil's star.

Caranthir inherited Nerdanel's condition, the only one of the sons who did. He didn't start using a cane until they were in Beleriand, so his is a from-memory recreation of Nerdanel's, made with Curufin's help. It also has metalwork details and a hinge. The textile wraps were his own addition, and the claw and beads were gifts from Haleth.
