Makeupkind

Makeupkind is Kanaya Maryam's Strife Specibus. This type of weapon is first introduced in Problem Sleuth. Like many of the weapons in the game, it is hidden away as an Innocuous Double, which in this case is a stick of lipstick.

The Homestuck version is designed to do so technologically, as Weapon/Object Duality does not exist in Homestuck outside the Midnight Crew Intermission. In fact, the narrator has even mentioned getting hysterical when talking about this weapon - a callback to Hysterical Dame, who also wielded a Chainsaw/Lipstick.

Lipstick
This is Kanaya's weapon before Sgrub starts. She uses the chainsaw aspect of the makeup to shape the foliage around her home to be the shape of Skaian clouds. As for the makeup, even though a troll's lips are naturally black, HS 4226 (they can always be blacker), and a lady with a true sense of style knows this. This lipstick allows Kanaya to have either black or jade green lips.

When cutting open the corpse of her Lusus, Kanaya draws a dotted line with the lipstick, then cuts along that line with the chainsaw.

The Banesaw
This lipstick/chainsaw appears in the Act 5 flash HS 4478 ("Make Her Pay"). Kanaya uses it to attack a large monster. Its troll horns with th esame shape as Kanaya's bent horn as teeth. It was created designed by Art Team member Aborted Slunk. While it is commonly theorized that the Matriorb was one of the objects used to alchemize this lipstick, the artist's intention was for Kanaya to have alchemized it using her own horn, similal to how ghost images of Dave Strider and Charles Dutton have been used in alchemizations, Canon is silent on the issue. The bat wings and eye come from an unknown alchemization.

It is the deadliest chainsaw in the universe.
