The SOG Bulwark FLK delivers professional-grade cutting performance in a compact EDC package designed for demanding daily use. This folding knife combines premium D2 tool steel with advanced manufacturing techniques to create a blade that maintains its edge through extended cutting tasks.
What Makes This Different
The Bulwark FLK features cryogenically treated D2 steel with black PVD coating, providing superior edge retention compared to standard stainless steel folders. The cryo treatment refines the steel's grain structure, increasing hardness to 60-62 HRC while the PVD coating adds corrosion resistance and reduces friction during cutting. This combination delivers cutting performance typically found in fixed blades within a convenient folding design.

Field testing demonstrates the D2 steel's ability to process cardboard, rope, and wood without frequent resharpening. The drop point profile excels at precision cutting tasks while maintaining enough belly for slicing applications. The Micarta handle material provides consistent grip texture that improves with use, making this knife suitable for extended cutting sessions in various weather conditions.
