Spyderco Thin Line Series FAQ

The Spyderco Thin Line Series honors law enforcement and firefighters by adding distinctive visual accents and charitable contributions to several of the brand's most iconic folding knives. These models retain the proven performance of the standard versions while supporting foundations dedicated to first responders.

Which models are included in the Spyderco Thin Line Series?
The Spyderco Thin Line Series features modified versions of the Delica 4, Endura 4, and Rescue 3 models. A Thin Line version of the Endela is also produced for those seeking a mid-size option between the Delica and the larger Endura.
What makes the Thin Line knives different from standard models?
These knives are distinguished by colored back spacers and matching handle liners—blue for the Thin Blue Line and red for the Thin Red Line—that are visible through the handle scales. Additionally, each knife in the Spyderco Thin Line series includes a specific blade engraving on the show side to commemorate the service branch it represents.
What charities do the Spyderco Thin Line knives support?
Proceeds from the Thin Blue Line series are donated to the Tunnel to Towers Foundation, which supports law enforcement officers and their families. Sales of the Thin Red Line knives benefit the Wildland Firefighter Foundation, providing assistance to fallen or injured firefighters.
What blade steel does the Spyderco Thin Line series use?
The knives in the Spyderco Thin Line series utilize VG-10 stainless steel, a Japanese-made alloy favored for its balance of edge retention and corrosion resistance. The series offers various edge configurations, including the fully serrated SpyderEdge on the Rescue 3 and partially serrated CombinationEdges on the Delica and Endura models.
What handle materials are used in this series?
The Spyderco Thin Line series uses lightweight Fiberglass Reinforced Nylon (FRN) handle scales featuring a Bi-Directional Texture for a secure grip. The colored liners are integrated into the interior of these FRN scales, providing a subtle pop of color along the handle's edges and spine.
