Spyderco Double Stuff 2 Sharpening Stone 303FCBN2

• CBN surface – harder than silicon carbide, easily sharpens even super steels (S90V, M4, Maxamet…)
• Compact and lightweight – ideal for carrying in a pocket, backpack, or EDC pouch
• Double-sided – everything you need for edge maintenance in one stone
• Dry use – no water or oil needed, ideal for quick use anywhere
• Leather pouch – protects the stone and also works as a stropping surface
• 🔴 Limitations
• Small size – less suitable for large blades or systematic sharpening of multiple knives
• Coarser CBN structure – does not provide a “mirror” finish like ceramic or Arkansas stones
• Higher price – premium material is reflected in the price (approx. 70–90 USD)
• 💬 What the community says
• “This thing sharpens Maxamet in the field like nothing else I’ve used.”
• “It’s a practical and sharp solution for travel—I keep it with my knife all the time.”
• “CBN changed the way I approach everyday sharpening. Small stone, big performance.”

• Cleaning: Simply wipe with a dry cloth or nylon brush, or use isopropyl alcohol if needed

Storage: Keep it in the included pouch – the CBN surface is durable, but stones can be worn by contact with other metal objects

• Stropping: You can optionally use the reverse side of the pouch for fine edge touch-up
