Founded by mechanical engineer Michael Sayers, Rivery makes every part in-house from 6061 aluminum. Both knives take standard SK5 utility blades, change blades with no tools, and are fully user-serviceable.

It accepts standard replaceable SK5 utility blades from most major manufacturers, and swapping in a fresh edge takes seconds.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre OTF knives legal, and is the Rivery Manufacturing Zero legal to carry?\u003c\/strong\u003e\u003cbr\u003e\nYes. The Rivery Manufacturing Zero Smooth Operator (Zero-M-OTF-S-6061-Gray) is a manual OTF knife — the blade is deployed by hand, not by a spring or button — so it is legal to carry in all 50 US states. Knife laws that restrict OTF knives target automatic (switchblade) OTFs; because the Zero is fully manual it falls outside them. Always confirm your local ordinances.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat states are OTF knives illegal in?\u003c\/strong\u003e\u003cbr\u003e\nRestrictions vary by state and generally apply to automatic (switchblade) OTF knives rather than manual ones. Because the Rivery Manufacturing Zero Smooth Operator (Zero-M-OTF-S-6061-Gray) is a fully manual OTF utility knife with no automatic deployment, it is legal to carry in all 50 US states — but always check your local ordinances.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does an OTF knife work, and how does the Rivery Manufacturing Zero deploy?\u003c\/strong\u003e\u003cbr\u003e\nThe Rivery Manufacturing Zero Smooth Operator (Zero-M-OTF-S-6061-Gray) uses a manual key-and-spring out-the-front slide: push the slide forward to extend the blade for cutting, and it retracts automatically when you release it — the “click and clack” action. There is no automatic or assisted deployment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is an OTF knife?\u003c\/strong\u003e\u003cbr\u003e\nOTF stands for “out the front” — the blade deploys straight out of the front of the handle instead of pivoting on a hinge. The Rivery Manufacturing Zero Smooth Operator (Zero-M-OTF-S-6061-Gray) is a manual OTF utility knife: you slide the blade out by hand and it auto-retracts, pairing OTF deployment with a standard replaceable utility blade.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere can I buy the Rivery Manufacturing Zero Smooth Operator (Zero-M-OTF-S-6061-Gray)?\u003c\/strong\u003e\u003cbr\u003e\nYou can buy the Rivery Manufacturing Zero Smooth Operator (Zero-M-OTF-S-6061-Gray) at Going Gear, an authorized Rivery Manufacturing dealer.\u003c\/p\u003e","brand":"Rivery Manufacturing","offers":[{"title":"Default Title","offer_id":43360104579107,"sku":"Zero-M-OTF-S-6061-Gray","price":70.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0096\/9736\/2020\/files\/zero-m-otf-s-6061-gray-front-view_d26f01d4-1652-4b10-8a9a-fad097d01678.jpg?v=1784173356"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0096\/9736\/2020\/collections\/Image_53.jpg?v=1784398204","url":"https:\/\/goinggear.com\/collections\/rivery-manufacturing.oembed","provider":"Going Gear","version":"1.0","type":"link"}
