The KA-BAR Becker BK18BK Black Harpoon is a compact fixed blade designed for outdoor and field use. Built from 1095 Cro-Van steel with a protective powder-coated finish, it offers durability, edge retention, and ease of maintenance in demanding environments.
The harpoon-style blade profile provides added control for detailed cutting tasks, while maintaining versatility for general camp and field work. Paired with a durable Ultramid handle and MOLLE-compatible Celcon® sheath, the BK18BK is built for adaptable carry and consistent performance.
Carbon steel blades should be cleaned, dried, and lightly oiled after use to maintain performance and prevent oxidation.

USMC-ISSUE COMBAT KNIVES
Named after a 1923 fur trapper's letter — "kill a bear." Standard-issue USMC combat knife since 1942.
KA-BAR's roots go back to 1898 in Olean, New York — originally the Tidioute Cutlery Company, later Union Cutlery. The KA-BAR trademark itself came from a 1923 letter from a fur trapper who killed a wounded bear with one of the company's knives after his rifle jammed. The legible fragments "ka bar" stuck. On December 9, 1942, USMC adopted the design as the USMC Mark 2 Combat Knife — the icon. The Becker line, designed by Ethan Becker of Becker Knife & Tool, extends KA-BAR's Master Series into bushcraft and tactical territory.

Answers, straight up.
Product-specific questions on the left. Shopping with SRO on the right. Both open-ended — hit us if we missed one.
How long does shipping take?
Most orders process within 1–3 business days from our warehouse. From there: 5–7 business days economy, 2–3 business days expedited, or overnight if you need it fast. Free economy shipping on orders over $150 (contiguous US). Alaska, Hawaii, and Pro Eagle / freight items are quoted at checkout. You’ll get a tracking number and link the moment your order ships.
What’s your return policy?
30 days from the day your order arrives. Gear has to come back unused, with all original tags, stickers, and packaging intact. For standard items we’ll send a prepaid return label and deduct return shipping from your refund. Oversized or freight returns are on you, unless the item showed up damaged, defective, or wrong — in which case we cover it.
Refunds hit your original payment method within 10 business days of approval.
What can’t I return?
Final-sale items, gift cards, food and drink products, personal-care items, anything customized or engraved, briefs (hygiene), and hazardous materials. If you’re not sure whether something qualifies, email us before you order — we’ll tell you straight.
Do you ship outside the contiguous US?
Yes. Alaska, Hawaii, and US territories ship on freight-quoted rates calculated after checkout. International orders are available worldwide at variable rates; duties and import fees are the customer’s responsibility. EU customers get a 14-day cancellation window per EU consumer law, on top of our standard return policy.
My package arrived damaged — what now?
Email info@stayreadyoutdoors.com within 7 days of delivery with your order number and clear photos of the damage (product + packaging). We’ll replace, refund, or ship a return label on us — no back-and-forth. Damaged, defective, or wrong-item claims never cost you shipping.
Can I talk to a human before buying?
Yes. Email info@stayreadyoutdoors.com — we answer every message ourselves, usually within a few hours during business days. We carry this gear, we use this gear, and we’d rather talk you out of a kit that doesn’t fit your mission than sell you the wrong one.
