No workbench, 15s, yields 1
Faster at a higher workbench: 7.5s at Workbench Level 1, 3.75s at Workbench Level 2 or 3.
Every player starts with this blueprint. Researching it anyway costs 10 scrap at a Research Table.
Keeps is the share of what the tool breaks off that reaches your inventory. The rest is destroyed with the swing.

What the Bone Knife gives back in each recycler
| Recycler | Efficiency | You get |
|---|---|---|
| Red recycler | 75% | 22 + 50% Bone Fragments |
| Green recycler (powered) | 60% | 18 Bone Fragments |
| Green recycler | 50% | 15 Bone Fragments |
| Yellow recycler | 40% | 12 Bone Fragments |
The Bone Knife breaks down into Bone Fragments.
A recycler takes one at a time.
Figures are for one item in perfect condition. Each recycler’s name opens its full table at this item. “22 + 50%” means 22 every time and a 50% chance of one more.
8 skins on the Steam Market change how the Bone Knife looks, from $1.67 to $6.32.
Also listed: one Twitch or Kick drop, marked “Drop”. It never reaches the market, so it has no price.
In Rust, Bone Knife is a melee weapon in the Weapons category (item ID #1814288539, console shortname knife.bone). When harvesting, it clears a crocodile node in 13 swings while keeping 100% of the yield. Inventory storage holds a single unit per slot, and uncollected ground drops despawn after 5 minutes.
Melee weapon crafted from bone fragments. Good for harvesting carcases.
Crafting Bone Knife in Rust takes 15 seconds by hand without a workbench, with all ballistics, crafting, and durability values read from the Rust game files. Shredding a spare copy at a green recycler recovers base materials at fifty percent yield (vs forty percent at safe-zone yellow units). Damaged copies repair at a Repair Bench for a fraction of recipe cost.
When comparing Bone Knife against related weapons in Rust, craft copies once the blueprint is unlocked (15 seconds per craft) and recycle surplus spares at an unpowered radtown green recycler (fifty percent base efficiency) rather than a safe-zone yellow recycler (forty percent efficiency) to maximize recovered materials.
| Item | Category | Stack Limit | Craft / Source | Tech Tree / Research | Green Recycler Yield |
|---|---|---|---|---|---|
| Bone Knife | Weapons | 1 per slot | Crafted by hand | 10 scrap (Table) | Not recyclable |
| Combat Knife | Weapons | 1 per slot | Workbench Level 1 | 30 node / 375 path | Not recyclable |
| Butcher Knife | Weapons | 1 per slot | World loot / gather | No blueprint | Not recyclable |
| Skinning Knife | Weapons | 1 per slot | Workbench Level 1 | No blueprint | Not recyclable |

Every player starts with the Bone Knife blueprint, so it never needs researching; a Research Table would still charge 10 scrap for it in Rust. It belongs to the Weapons category under numeric ID 1814288539 across 85 weapons, stacking to 1 unit per slot.
Dropped on the ground in Rust, the Bone Knife despawns after 5 minutes by default. Picking it back up into a player inventory or storing it inside a base container immediately resets that ground despawn timer, which the server scales by item rarity tier.
The Bone Knife has 32-bit signed item ID 1814288539 and shortname knife.bone in Rust. Server plugins, custom loot tables, Vending Machine listings, and automated Industrial Conveyor filter strings reference these two identifiers under the Weapons category (stack limit 1 unit per slot).
Server administrators in Rust spawn the Bone Knife in the F1 developer console by typing inventory.give knife.bone 1 or inventory.giveid 1814288539 1 for a single unit. Both console spawn commands require administrator or moderator privileges on the server, while regular players can bind a quick-craft shortcut key instead.
