Spyderco Endura 4 Thin Red Line Black FRN Folding Knife is a functional knife that honors the service and sacrifice of our nation's courageous firefighters. The "Thin Red Line" symbolizes the role first responders represent between the normalcy of our daily word and the chaos of life-threatening emergencies. This series of knives honors their sacrifice with unique versions of Spyderco's most popular knives. The handle of these knives, made of textured black FRN for excellent grip, feature a "Thin Red Line" backspacer. The drop point blade is made of tough VG-10 stainless steel, which provides excellent edge retention. The shape of the blade provides excellent control and versatile cutting abilities, and the partial serration provides sawing options for those who want added functionality. These knives are also laser engraved with the motto "Save and Serve", further honoring the sacrifice of these professionals. This knife is an excellent addition to any collection. 

In addition to their uniqueness, Spyderco will donate a portion of all sales of “Thin Red Line” knives to the Wildland Firefighter Foundation, which provides immediate financial and ongoing emotional support, advocacy, and recognition to fallen and injured wildland firefighters and their families.
