Sung Jin-Woo's Kasaka's Venom Fang is a fan-made metal replica of the curved dagger from Solo Leveling, the blade Jin-Woo crafts from the fang of Kasaka, the venom serpent he kills in a C-rank dungeon early in his rise. This dull replica has a purple blade with red markings, a copper claw guard, and a white wrapped handle, and it comes with a wooden display stand. Available in two versions for Sung Jin-Woo cosplay and display, and sold as a set with the Knight Killer on that product page. Like everything at Sword Slice, it is an independent tribute to the series rather than official merchandise.

Kasaka's Venom Fang is the first weapon Sung Jin-Woo truly earns in Solo Leveling. In a C-rank dungeon he hunts Kasaka, a giant venom serpent, and uses its fang as the base for a curved dagger. The blade carries a paralysis effect from the serpent's venom, which makes it a useful tool for a low rank hunter who has to fight smarter than his opponents.

Jin-Woo pairs Kasaka's Venom Fang with the Knight Killer after the Job Change quest, and the two daggers become his signature dual wield set through the Red Gate and Demon Castle arcs. He later finds Rasaka's Venom Fang, a stronger companion blade from a related serpent, before moving on to the Demon King's Daggers and Kamish's Wrath. This replica captures the sweep of the fang shaped blade with its purple finish, red markings, claw style guard, and wrapped handle.

Frequently asked questions

Is this Kasaka's Venom Fang from Solo Leveling?

Yes. This is a replica of the curved dagger Sung Jin-Woo makes from the fang of Kasaka the venom serpent, one of the two daggers he dual wields early in Solo Leveling.

What is the difference between V1 and V2?

Both are the same size and price. V1 is our original casting and V2 is a newer production run with slightly updated finish and detailing. Check the photos for the current look of each.

Is the blade sharp?

No. The edge is dull and the dagger is intended for display and cosplay. It is still solid steel, so handle it with care.

Can I buy Kasaka's Venom Fang together with the Knight Killer?

Yes. The Knight Killer product page has a set option that includes both daggers and a wooden display plaque, which is the easiest way to get Jin-Woo's full early dual wield loadout.

Can I use it for Sung Jin-Woo cosplay at a convention?

Yes. It is light enough to carry all day. Metal props usually need to be peace bonded at conventions, so check your event's prop policy before you go.

How do I clean and maintain the blade and wrap?

Wipe the steel with a dry cloth after handling and keep the faux leather wrap dry. A light coat of oil on the blade once or twice a year keeps the two tone finish bright.

Does it come with a stand?

Yes, a wooden display stand is included so the dagger is ready for a shelf or desk when it arrives.

What is the difference between Kasaka's and Rasaka's Venom Fang?

Kasaka's Venom Fang is Jin-Woo's first serpent dagger and has a purple blade with red markings and a copper claw guard. Rasaka's Venom Fang comes later from a stronger serpent and has a black blade with a purple claw guard. We carry both in the Solo Leveling collection.

Is there a foam version?

We offer Rasaka's Venom Fang and the Knight Killer in high-density foam. Kasaka's Venom Fang is currently metal only.

Is this a good first Solo Leveling replica?

Yes. It is one of Jin-Woo's most recognizable weapons, comes with a stand, and sits at a lower price point than the later daggers, which makes it a popular starting piece.
