1.How do you ship outside the USA? We can ship via FEDEX if you buy small quantity. 2.How long will it arrive you? It takes 7 or 9days to arrive you. 3.How to choose a suitable outdoor folding knife? The following factors should be considered when choosing: Blade length: 2.5-3.5 inches are suitable for daily carry, 3-4 inches are suitable for heavier outdoor tasks. Blade material: Stainless steel: Corrosion-resistant, suitable for wet environments, low maintenance. Carbon steel: Sharper, stays sharper for longer, but requires maintenance to prevent rust. Locking mechanism: Such as Axis Lock, Frame Lock or Liner Lock, to ensure safe use. Benchmade's Axis Lock is particularly suitable for one-handed operation. Handle material: G10, carbon fiber or thermoplastic composite (such as Grivory) are durable and lightweight. Weight and portability: Lightweight knives (such as Benchmade Bugout, only 1.9 ounces) are suitable for long-term carry. Purpose: Determine whether it is used for light tasks (such as cutting food) or heavy tasks (such as splitting wood) to choose the appropriate blade thickness and design. Advice: Try handheld knives to ensure a comfortable grip, and give priority to well-known brands such as Benchmade, Spyderco or Kershaw, which provide high quality and lifetime warranties. 4.How to maintain our Kingstone Tools. *The best way to keep a tool clean is to wipe it down after every use, but for the less-diligent, periodic cleanings will suffice. *Q-tip, toothbrush, and toothpicks are particularly good at removing grime, paying particular attention to the pivot and handle. *Use warm water and mild dish soap to thoroughly wash the knife, please keep the knife dry with a rag or better tools. *Once it's clean and dry, it's suggested to maintain the blade by wiping some Anti Rust Oil.  Note: Don’t take apart your knives or tools — it might void the manufacturer’s warranty.
