The F4 is our general purpose bushcraft style survival knife. Its 4" blade is robust enough to withstand the toughest survival situations, yet refined enough to breeze through any bushcraft task. Constructed from 5/32" thick CPM®3V high-alloy steel, these knives are exceptionally durable. The spine will rain sparks from a ferro rod or scrape cedar bark for tinder. The sturdy full tang is skeletonized to reduce the overall weight of the knife, making the F4 an ideal carry companion in the field or around town. You'll find the ergonomic 5" handle has no hotspots, providing a seamless interface between your hand and the tool. Whether you're crafting a bow drill or field dressing an elk, the F4 will get the job done right.
