Folding Knife Spyderco Endura 4 C10S

• Stainless steel scales add weight, robustness, and design elegance – ideal for more demanding environments
• Spyder
• Edge serrated blade cuts rope, cardboard, and textiles exceptionally well – up to 24% more effective cutting edge
• Never-ending VG‑10 reliability – easy sharpening and good edge retention are appreciated by the community
• Back-Lock mechanism – simple, durable, and less prone to jamming even in dust
• Universal clip system – adapts carry options for everyone
• 🔴 Limitations
• Stainless steel construction without screws (on some models) can make servicing more difficult; the FRN version is worth considering for easier maintenance
• Slower closing with the Back-Lock and the need to “work with” the blade’s movement – less suitable for fast flicking
• Serrated edge tears through durable materials, but sharpening is more demanding – a special file is needed
• 💬 The community says
• “Endura absolutely surpassed my expectations… The all‑stainless feels amazing in hand.”
• “Spyder
• Edge serrations deliver up to 24% more cutting surface… makes short work of fibrous materials.”
• “Back locks are not the best for flick-opening… with practice and break-in, it is possible.”
• “VG‑10 holds an edge well and is easily sharpened to hair‑popping sharpness.”

• Cleaning and oiling: External pins and the mechanism can be lightly disassembled (on the FRN model)

Sharpening SpyderEdge – use thin files for the serrations; the plain section can be touched up with diamond/ceramic

Lock lubrication – light oiling ensures reliable operation

Check screws and clip tightness – important during carry
