Sturdy supplies for your everyday adventures.
Natural Sharpening Stone
A good knife will serve you well for decades, but even the best ones — like Opinel's terrific pocket knives — need a tune-up every now and again. But with one of these, you can keep any blade as sharp as the day you bought it.

The stone is sourced from Lombardi, Italy, where the quarries have been famous for producing the world's most effective sharpening gear ever since the 15th century thanks to a perfectly uniform blend of quartz and carbonates.
