Butterfly Knife

The Butterfly Knife is the showstopper of CS2's ★ melee collection, and SIH tracks every skin for it with live prices across 28+ marketplaces, float inspection, and 3D previews. Known in CS:GO and CS2 as the balisong-style flip knife, the Butterfly Knife is defined by its iconic two-handed opening animation: handles pivot around the blade in a fluid flourish that no other knife can match. That distinctive flip routine has made it one of the most spectated knives in the game, commanding a premium even among ★ rarity items. It appeals equally to collectors who value aesthetic rarity and to players who simply love showing off during the buy phase. The most coveted finishes are Fade (with its violet-to-yellow gradient that demands a high fade percentage for top value), Doppler (spanning phases from blue-black to pink and the rare Ruby/Sapphire/Black Pearl), Marble Fade (the candy-cane fire-and-ice pattern that collectors obsess over), and Tiger Tooth (bold golden-orange metallic). Crimson Web and Slaughter offer more accessible price points while still delivering strong visual impact. On any of these finishes, float matters: a Factory New edge looks dramatically sharper, and Doppler phase or Fade percentage can push prices into ranges usually reserved for rare stickers. SIH lets you cross-reference Butterfly Knife listings by wear tier, specific float range, pattern seed, and Doppler phase, then surface the best offer across Steam Market, Buff163, CSFloat, Skinport, DMarket, Waxpeer, and 20+ additional platforms side by side. Track price history to spot dips, or add your existing knife to the inventory calculator for an accurate valuation of your CS2 collection. Filter by your budget, check the float, and lock in the lowest price, SIH has every Butterfly Knife listing in one place.
