As seen in the cinematic reveal trailer for Assassin's Creed Valhalla, protagonist Eivor uses a conspicuous version of the hidden blade where the actual blade can be seen on top of the forearm as opposed to being hidden on the bottom. Ubisoft decided to remove the "hidden" aspect of the hidden blade in order to better fit the tone of Valhalla and Eivor's culture.

"It is a deliberate decision," Assassin's Creed Valhalla narrative director Darby McDevitt said on Twitter. "It's something that Eivor feels very strongly about. When he or she gets a hold of this hidden blade, it occurs to Eivor that it would be much more interesting to let people see this weapon, to be conspicuous about it. Vikings were known as having a sense of honor and it was very important that when you killed somebody, that you let people know that you killed them."

McDevitt continued: "Oftentimes, people would not be punished for murder if they had a small justification, like say somebody insulted you. They would not be punished for the murder as long as they admitted to it, as long as they stated openly that 'Yes, I killed that person because we got into combat.' And so having the hidden blade visible is actually kind of an extension of that honor. We want this conspicuous aspect of the blade to be reflected in the way that Eivor presents him or herself to the world."
