Fang of Haynekhtnamet
The Fang of Haynekhtnamet is a literal fang which was carved into a blade and fashioned into a small dagger. It is named after Haynekhtnamet, a mythical wamasu from the Shadowfen region of Black Marsh. Scholars believe that Haynekhtnamet is not actually a single creature but a series of wamasu, and as such it's possible that there are multiple Fangs.
The most famous Fang of Haynekhtnamet was created by a score of Nords who fought Haynekhtnamet for seven days and nights before finally bringing the creature down, believing it to be a dragon. One of the survivors took a fang as a trophy, and it was later carved into a dagger which mysteriously houses some of the beast's magical properties. The dagger grants the wielder the ability to shock an opponent, and has been seen occasionally by traveling heroes throughout history.
There is evidence of a second Fang of Haynekhtnamet, which was taken from a wamasu in 2E 582. Fashioned in an Argonian style, this jagged blade was heavily befouled and would cause disease in anyone it struck.

Fangs of Sithis
The Fangs were gifted to the Night Mother by Sithis, the Dark Husband, who in turn gifted them to the Shadowscales. It is said that a single Shadowscale wielding the Fangs could lay waste to entire cities not just via mass killings, but also by causing crop-failures and famine. However, most are unable to safely wield the Fangs, as they feed upon the wielder's mind and soul, causing the weak-minded either to go mad, or become mindless agents of Sithis who are devoid of free will.
Fearstruck was a Daedric artifact created by the Daedric Prince Boethiah. It took the form of a shield. It belonged to Lyrisius, a hero from Tamriel famous for leading his army against the Akaviri slave traders in their homeland of Akavir. The shield was utterly destroyed in the First Era by the fiery breath of a wyrm who Lyrisius encountered after his army was routed.
Despite the destruction of the artifact many centuries prior, there were known replica shields styled after Fearstruck circa 2E 582. These replicas depicted Fearstruck as an ebony shield emblazoned with Boethiah's symbol of a fist surrounded by writhing golden snakes.
Feyfolken is a supposed artifact of the Daedric Prince Clavicus Vile, which is only known from a series of historical fiction books. It is a quill enchanted by a daedra by the name of Feyfolken serving Clavicus Vile at the request of Thaurbad, a sage for the Temple of Auri-El. It transfigures the writing of the user into scripture of unparalleled quality.The trade-off of wielding such an item is that the quill manipulates the thoughts of its beholder.
Fists of Randagulf
The Fists of Randagulf were worn by Randagulf, one of the mightiest warriors from Skyrim in Tamrielic history. He finally lost the gloves, and his life, when High King Harald conquered Skyrim circa 1E 143-1E 221. King Harald respected this great hero and took Randagulf's gauntlets for his own. After King Harald died, the gauntlets disappeared. The King claimed that the Fists granted the bearer added strength.
Flask of Lillandril
The Flask of Lillandril is a magical flask that absorbs and reflects magic of all kinds. Its anti-magic property also prevents mages from detecting its location. The flask was discovered around the year 1E 470 by a group of elves living in the Summerset Isle city of Lillandril. The elves spread news of their discovery, enough to make it an artifact of song and legend. It became the city's symbol and was displayed on their banners.
The elves used the flask to perform favors for the barons of Summerset Isle by keeping in check the magical power of the Bosmer in Valenwood. One legend says that a stable boy defeated the High Wizard of Valenwood using only the flask. After some time, the elves who discovered the flask feared that Bosmer assassins would kill them, so they fled for Daggerfall, hoping to buy safety from the Direnni. The elves shipwrecked off the southern coast of Stros M'Kai, killing all of them according to legend, and the Flask of Lillandril was lost.
The Folium Discognitum is a Daedric artifact created by Sheogorath. It is a tome of knowledge, filled with insights compiled from the ramblings of madmen. The pages bear near incomprehensible scrawls that move to avoid your gaze when read. The power obtained from reading these insights is the equivalent of absorbing at least six skyshards.
Fork of Horripilation
The Fork of Horripilation is a cursed artifact created by the Daedric Prince Sheogorath, who refers to it affectionately as Forky. In appearance and in function, it is a mundane iron fork. However, it is imbued with an enchantment which excites and synergizes magicka around it, and can produce dramatic results when held by certain people. Sheogorath is fond of forcing mortals to use it as a weapon, in which case it curses the wielder with Fork's Wound, a magical effect which stunts the wielder's magicka or drains it completely. The term horripilation refers to the standing of hairs on end due to cold, fear, or excitement. In the context of the fork, excitement arises within Sheogorath when he convinces mortals to use the fork, while fear is evoked in mortals from just touching it, resulting in horripilation. The Fork smells lightly of roast beef.
