In the aftermath of the September 11 attacks, advanced tactical knives, both folding and fixed-blade, were refined for use by US and allied special forces in operations throughout Afghanistan's Hindu Kush mountains. By 2001, companies like Benchmade began producing knives that emphasized durability, versatility, and ease of use in high-stakes environments. These modern tactical knives have since become essential tools for military personnel, reflecting the ongoing evolution of combat gear in contemporary warfare.

These tools ground contemporary war poetry in gritty realism, as seen in works by veteran poets addressing asymmetric warfare and psychological tolls.
