Among Butterfly knives, Fatal Violet is the easy pick when you want a clean, two-tone identity instead of busy artwork. Internally so_purple, listed as knife | Fatal Violet, category knife, rarity Rare. Valve’s blurb is straightforward: key parts get a full black-and-purple paint job. The flavor line about nobility masking something darker fits the mood—no flash, mostly atmosphere.

It landed 15 March 2017 with the Spectrum 2 Case and the Take a trip to the Canals update, Valve-designed (not a Workshop skin). Collectors should treat it as a Spectrum 2-era Butterfly finish: drop odds and float spread are tied to that case, not a separate pipeline.

Shopping verdict

Worth it if you care about Butterfly animation plus a restrained purple block, and you’re willing to pay for a float band that keeps purple intact. Skip or go budget if you need top-tier flex—Rare isn’t Covert—and you’re fine with FN prices on louder finishes.

Wear target: Float 0.06–0.80. Lower wear keeps purple saturation across blade and handle; high wear pushes black forward and exposes edge wear fast on a solid color. Decide FN/MW vs BS before you sort listings.

Where to buy: Filter by wear on C5GAME or the Steam Community Market, then compare the same float band side by side—thumbnails lie on solid colors.

What you’re actually buying

Finish type is solid color. Purple and black cover blade, handle, and related parts with a minimal pattern layer, so lighting and angle do most of the work in-game. Scratches and paint loss show up aggressively as float climbs; purple “shrinks” and black reads louder, so two copies at different wear can feel like different skins.

Rare tier means it’s not the ceiling for knife prestige, but the Butterfly inspect loop still sells low-wear, clean fields—many buyers chase specifically for that.

Expert notes

• Inspect in a server, not just on a listing: flip and spin repeatedly; check handle–blade transitions and screw areas—solid finishes punish micro-scratches.
• Set a max float before you bid; purple retention drops faster than you expect once you leave the low-FN band.
• Case context: Spectrum 2 only—no alternate origin story; plan budget around case knife economics.
