Toor Krypteia S Specifications

Toor Krypteia S vs. Toor Barrow

The Krypteia S and Barrow are both American-made Toor fixed blade knives, but their different dimensions and materials make them suitable for different carry preferences.

Toor Krypteia S: Features a 4-inch M4 steel blade, quarter-inch blade thickness, textured G10 handles, and a 7.2-ounce weight. Its more substantial design is suited to customers who prefer a robust field-oriented fixed blade.

Toor Barrow: Uses a shorter 2.875-inch CPM MagnaCut blade with thinner blade stock and lightweight construction. It emphasizes precise utility cutting and easier weight-conscious carry.

Choose the Krypteia S if you prefer thicker blade stock and a larger blade. Consider the Barrow if you prioritize reduced weight, a shorter blade, and MagnaCut steel.
