Since 1976, Spyderco has redefined what a folding knife can be. Founded in Golden, Colorado by Sal and Gail Glesser, Spyderco pioneered the pocket clip, the one-handed opening Round Hole™, and serrated edges on folding knives — features now considered standard across the entire industry. Today, Spyderco produces knives in Golden, Colorado, Seki City Japan, Taichung Taiwan, and Maniago Italy, bringing world-class manufacturing to every price point in their catalog. From the featherlight Delica 4 to the legendary Paramilitary 2, from salt-proof LC200N Salt Series folders to ultra-premium K390 and CPM MagnaCut collector pieces, every Spyderco knife is backed by a Limited Lifetime Warranty and Spyderco's complimentary LifeSharp® sharpening service. Knifeworks is a proud authorized Spyderco dealer — every knife we sell is 100% genuine, sourced directly from Golden, Colorado.
