Possessing Hagoromo's sealing talent was a big opportunity to make them weapon specialists of the highest caliber. They could have used their fuinjutsu ability to make enchanted weapons similar to the Sage's tools, Itachi's spirit weapons and Minato's kunai.
I think they did in fact possess such weapons and it's one of the reasons they were so feared, when you look at what a single seal did for Minato, it made him and Tobirama borderline god tier, imagine what type of seals Uzumaki prodigies would have been able to develop.
Maybe Orochimaru's Kusanagi sword is one of the remaining artifacts that originally belonged to Uzumaki since it was meant to be a direct counter to Totsuka, a Susanoo weapon.
That along with Sage tools and FTG seal are examples of how broken Naruto's clan would have been and why they were targeted first long before Uchiha.
