Bold Color, Serious Automatic Performance

The Heretic Colossus Auto OTF is built for users who want a larger, more commanding out the front automatic with unmistakable visual presence. This Toxic Green configuration pairs aggressive styling with Heretic’s proven automatic action, delivering a knife that feels just as confident in hand as it looks.

Featuring a 3.5 inch MagnaCut tanto blade with a durable black DLC coating, this Colossus is designed for strength at the tip, corrosion resistance, and long term edge performance. The Toxic Green aluminum handle is accented with a black traction inlay, adding grip and control without compromising the clean, tactical profile.
