Razor Blade

A rare active trinket that triggers the tk_RazorBlade ability — likely a precise, high-damage cut that inflicts Bleed or a similar physical DoT. As a rare-tier cutting weapon, Razor Blade likely deals more damage or applies a stronger version of the Bleed effect than its uncommon counterpart Carving Knife. Best used in Bleed-focused builds alongside Snaggle Tooth or Paper Hat for maximum DoT stacking.

As an active trinket, Razor Blade consumes a durability charge per use rather than firing passively. This means you control exactly when the cut lands, making it possible to time it for maximum effect — leading with Razor Blade to apply Bleed, then following up with basic attacks that Snaggle Tooth also applies Bleed to, stacks the DoT to higher levels quickly. The exact damage and Bleed stack amount are worth confirming in-game.

Ideal for Bleed-synergy builds that use Snaggle Tooth, Demonic Mask, or Paper Hat to amplify Bleed damage. Combine with Nightshade or Empty Syringe to make each Bleed stack hit harder. If you have Carving Knife as well, Razor Blade's rare rarity likely means it applies more Bleed per use or deals additional physical damage on the cut itself.
