ONE DESIGN LANGUAGE.
TWO AVAILABLE PROFILES.
A substantial fixed-blade design built around high-carbon steel, a molded textured handle and dedicated protective sheath. Choose between the two available configurations shown in the product selector.
🔎 Choose your configuration
Two Models. One Consistent Construction Style.
Your product photography shows two available configurations. Because the supplied images do not establish separate official SKU names or dimensional specifications, they are identified here as Model A and Model B rather than assigning unverified names.
Standard Profile
The first available configuration shown in your product gallery, paired with the matching protective sheath and retention hardware.
Alternate Profile
The second available configuration shown in your product gallery, retaining the same overall dark-blade, coyote-handle and sheath visual language.
Store setup tip: Replace “Model A” and “Model B” above with your actual Shopify variant names once the supplier SKU names are confirmed.
Modern military equipment design
A recognizable fixed-blade profile defined by muted tactical finishes, a textured molded grip and a dedicated retention sheath.
🧱 Construction overview
Built Around Three Core Components.
Current Ontario catalog specifications for the ON6504 list a 1095HC blade, Dynaflex handle and polyester elastomer sheath.
High-carbon blade steel listed in the current Ontario Knife Co. specification.
Molded synthetic grip with a deeply ribbed, contoured exterior.
Dedicated protective sheath construction with retention webbing.
⚙️ Detail-focused construction
Designed as a Complete Blade-and-Sheath System.
Rather than presenting the blade and carrying system as unrelated pieces, the design uses a coordinated handle, guard, sheath and retention layout.
🧱 High-Carbon Blade
Current ON6504 documentation specifies 1095HC steel at 57–59 HRC.
✋ Deeply Ribbed Grip
Pronounced molded ribs make the handle visually easy to identify while adding a textured grip surface.
🛡️ Protective Sheath
The matching sheath covers the blade during appropriate storage and transport.
🟤 Coordinated Coyote Hardware
Brown-toned handle and webbing create a unified, subdued equipment aesthetic.
🛡️ Protective storage system
The Sheath Is Part of the Overall Design.
Your supplied product photography shows the blade together with a full-length coyote-toned sheath, webbing and retention hardware.

Inspect and dry high-carbon steel after exposure to moisture.
🔍 Inspect Periodically
Check the blade, handle and sheath for visible wear or corrosion.
🛡️ Use the Sheath
Keep the edge enclosed when the item is not being inspected.
🔐 Secure Storage
Keep large fixed blades inaccessible to children and unauthorized users.
