Introduction

After the Great War, many surviving members of the US Navy's chief special operations force held on to what would become their most valuable survival tool. Despite years upon years of usage, the blade withstood the test of time, outlived its original owner and passed onto the next of kin or strangers lucky enough to get their hands on the knife. Over two centuries later, most knives were forgotten after their wielders met a violent end in the wilderness. However, some of the hardest scavengers recovered the knife, ignorant to the story of the mighty blade, ended up being traded like other common knives, waiting for the next worthy person to bring the legend back to the land and sea once again.

Features

- Completely original meshes and textures.

- 15 Modifications including texture swap.

- Optional knife sheath as a resource to use for your mod (you'll need a permission from me first).

Locations

POSSIBLE SPOILERS

Once your character reached level 30, Proctor Teagan, Arturo, and your settlement's weapon shop should sell it. There are few locations in the Commonwealth where you can obtain the knife at any point in the game. However, most of them are located under the lake, usually near submerged objects, so you'll need to be willing to go on a deep dive.

There's also a unique one hidden in one of the large bodies of water somewhere in the Commonwealth.

You can also search up the knife's ID using console command, "Ontario" is a recommended search term, make sure its signature is WEAP (which should be on the be the last item), then spawn it using "player.additem" command.

✨ Key Features

📊 Pros & Cons

✅ Pros

  • Community-approved with 202 endorsements and over 5,800 downloads.
  • Fills a niche for players tired of the overused Ka-Bar design.
  • Lightweight addition that doesn't overhaul the game.

⚠️ Cons

  • Last updated in 2020, so may not be compatible with the latest Fallout 4 patches or DLC.
  • No mention of custom animations or textures, so it might reuse vanilla assets.
  • Potential conflicts with other weapon mods that alter the same knife slot.
🎯 Is This For You?
For Fallout 4 players who want a more authentic SEAL knife for their stealth or survival playthroughs. If you're a collector of military-style weapons, this is a must-have. Skip if you're looking for gameplay-changing mechanics—this is purely a cosmetic weapon addition.
📦 Install:Easy· Under 1 minute

💡 Beginner Tips

  • Since it's a simple weapon mod, you can install it manually by dropping the files into your Data folder, but using a mod manager like Vortex is safer for tracking and uninstalling.
  • Check your load order—make sure this mod loads after any mods that modify the weapon list to avoid conflicts.
  • If you're using the Far Harbor DLC, test the knife in that area to ensure it works with the new enemies and environments.
