Needlekind

Needlekind is Rose Lalonde's and Roxy's Mom's Strife Specibus. John Egbert also acquired the specibus off Rose in order to preform the Scratch. It may also be Damara Megido's strife specibus, but this is not confirmed. At first this kind abstratus merely contained normal needles, but Rose has since alchemized needles that function as magic wands. This somewhat blurs the line between the Needlekind and the Wandkind Specibus.

Knitting Needles
These needles were given to Rose by John for her birthday, because he thought she needed a normal hobby. She first uses them (passive) aggressively in a Strife against her Mom, in which she threatens to electrocute herself using them. When Rose reaches the Land of Light and Rain she uses the needles in combination with the wool very effectively, easily taking down Imps and even a Lime Ogre.

She also uses them to actually knit things, like the head and arms of the Eldritch Princess or a laptop cozy or parts of the bunny she later gives to John.

Post-Scratch Rose uses a very similar pair of needles in combat, down to using it in combination with purple wool.

Needlewands
A pair of needles created with the Alchemiter. Rose has not used these in battle since their creation, as she made the considerably more powerful Thorns of Oglogoth by combining them with her Grimoire immediately after creating them.

Thorns of Oglogoth
An item alchemized from the Needlewands and the Grimoire for Summoning the Zoologically Dubious. These seem to be powerful weapons, capable of punching holes in caulk liches from a distance. They're also quite useful for burning things.

While it was inevitable that Rose would receive thorns, the description of these ones notes that any sane adventurer would drop them and flee. It was speculated that the Thorns have a negative effect on Rose psychologically, seemingly changing her behaviour. A similar theory was brought forward by Kanaya, who was concerned about Rose's allegiance with The Noble Circle of Horrorterrors and her frequent and almost brash usage of dark magic in tearing apart her own planet.

Ultimately it was revealed by, that the Thorns themselves had little influence in all this and that it was rather part of Rose's descent into Grimdarkness, presumably caused by the influence of the Horrorterrors.

It is later found within a chest Meenah Peixes finds in a dreambubble during Openbound.

Quills of Echidna
The Quills of Echidna are weapons first seen strapped to the back of the Uber Bunny. The needles look like white lightning and are named after Jade Harley's browser and denizen, Echidna. They are the literally Echidna's Quills taken from her thorny back. Thus the Quills relate to Fear No Anvil in that they are both very powerful weapons previously owned by Denizens.

The Quills of Echidna are needed to scratch the giant scratch construct to generate the scratch. Jade receives a set of Quills directly from Echidna through a series of shenanigans. John later uses one of them to activate the Scratch. They are shown to be of enormous size in their original state and during Cascade they have to be mounted on an arm above the Beat Mesa while John moves the Beat Mesa with his Breath powers.

Of note, the Echidna of Greek mythology was the mother of all monsters, and thus the name may be a reference to Rose's interest in the occult. Additionally, the real-life animals called echidnas have hedgehog-like quills, making the name a multi-layered reference.

Damara Megido has been seen with a smaller version of the Quills that she was able to hold in her hands, and used them to scratch the A1 session.

Thistles of Zillywich
The Thistles of Zillywich consist of one of the seven legendary weapons of cherubim folklore. The pair represents its namesake continent. It is one of two of such sets that contains more than one weapon. No further description of its origins is provided other than "Flippety dippety doo bup bup shrubber double floppy mumblescurry noodlescoop pizzabubble pizzabubble mip mip mip mip mip mip." Which may, incidentally, be a reference to the garbled text of Grimdarkness.
