How to Craft Knives in Blight Grab (Roblox)

In Blight Grab , knives are crafted using the game’s forging/crafting system , which works similarly to guns and other weapons: you combine loot items of matching rarity to increase your chances of getting higher-tier gear.

Crafting System Basics

From community guides and gameplay footage:

  • You gather loot items (materials) while exploring the map.
  • These items have rarity tiers (e.g., common, uncommon, rare, legendary).
  • At a crafting station / forge , you combine three items of the same rarity to try to craft a weapon of that tier.

The key rule repeated in guides:

“When crafting guns, don’t mix high rarity items with low ones… if you want a high-tier weapon, just gather tier three special items… if you want an uncommon gun, collect three uncommon items. And if you want a legendary gun, also collect three legendary items.”

Knives follow the same logic: to craft a better knife , use three materials of the same (higher) rarity.

Step‑by‑Step: How to Craft Knives

  1. Loot materials in-mission
    • Go into raids/zones and search containers, corpses, and special loot spots.
    • Prioritize cap 4+ loot (higher-tier items), as they’re more valuable and better for crafting high-tier gear.
  1. Return safely to base / safe zone
    • Use the map (press M) to find the extraction/return point (often marked by green smoke).
 * Make sure you actually **extract with your loot** ; if you die before extracting, you usually lose it.
  1. Open the crafting/forging interface
    • In your base/safe area, look for the forge or crafting station UI.
    • This is where you turn loot materials into weapons, including knives.
  2. Select knife crafting (if available) or general weapon forging
    • Some guides show a “Legendary Weapon Forging Recipes” section specifically for Blight Grab.
 * If there’s a dedicated “Knife” category, choose it; if not, knives are usually part of the general melee/weapon forging pool.
  1. Use three materials of the same rarity
    • For a basic/common knife : 3 common materials.
    • For an uncommon knife : 3 uncommon materials.
    • For a rare/legendary knife : 3 rare or 3 legendary materials.
 * Mixing rarities will usually **lock the result to the lowest tier** , wasting your better materials.
  1. Confirm craft and check results
    • After crafting, inspect your inventory to see if you received a knife and what tier/rarity it is.
    • Higher-tier knives typically have better damage, speed, or special effects , depending on the game’s current version.

Tips to Get Knives Faster

  • Farm high-cap loot zones
    Focus on areas that drop cap 4+ items , since those feed directly into rare/legendary crafts.
  • Play with a squad or stick to safer routes
    Blight Grab is an extraction-style game with zombies and other players; dying means losing loot.

Use high ground or safe spots during boss fights to survive and bring back more materials.

  • Watch for updates and recipe changes
    Newer guides (late June–early July 2026) mention specific forging recipes and progression tips, so checking recent videos or patch notes can help if the devs tweak crafting.

If You Meant “Grab Knife” Exploit/Script

Some older results online refer to “Grab Knife” as a script/exploit name , not an in-game crafting recipe.

  • Those are third-party cheat scripts , not official game mechanics.
  • Using exploits can get you banned and isn’t supported by Roblox or the game’s developers.
  • For normal gameplay, stick to the legit crafting system described above.

TL;DR: To craft knives in Blight Grab, loot same-rarity materials (ideally high-tier), extract safely, then use the forge to combine three matching- rarity items into a knife of that tier. Don’t mix rarities, and focus on high-cap loot to get better knives faster.
