If there is one thing My Knife Farm does well, it is making every new knife feel like a meaningful upgrade over the last one. From the first rusty blade you pull out of a basic case to the jaw-dropping earnings of a maxed-out Godly weapon, the entire game is built around the thrill of climbing the rarity ladder. But with so many tiers and weapon types in the game, it can be hard to know where each knife actually stands and whether it is worth keeping, upgrading, or selling on the spot.
This tier list ranks every major knife category in My Knife Farm from the absolute best to weakest, so you always know what you are working toward and what is worth dropping the moment something better rolls through.
How the Ranking Works
Knives in My Knife Farm are ranked primarily by their rarity classification, which determines both their base earnings and their income ceiling at max level. A higher rarity means a higher starting value per knife cycle and a more expensive but more rewarding upgrade path.
Alongside rarity, the specific weapon type and skin variant also play a role – a Rainbow or Blue Gem skin on any given knife is worth significantly more than its base version of the same tier. The in-game Index lets you track every knife you have unlocked, and using it as a reference while reading this guide will help you understand exactly where your current collection sits.
God Tier: Ninja, Fruit, and Historical
At the very top of the knife hierarchy sit the Ninja, Fruit, and Historical tier weapons. Ninja and Fruit cases cost upward of 60 trillion in-game cash just to open, which means reaching them is a sign that your farm is already operating at a level most players never see.
A Rainbow Ninja sword, for example, is one of only three Timeless weapons in the entire game and generates income that can push a player from billionaire to quintillionaire status in a single session. Fruit weapons from the Monkey Duffy case start at over one billion per knife at Level 1 – before a single upgrade has been applied.
Historical tier sits above even Ninja and Fruit in theory, but its drop rate is so astronomically low that many dedicated players question whether it appears in practice at all. Those who claim to have seen Historical cases describe them as the single most valuable weapons in the game, capable of generating income at a scale that cannot be meaningfully expressed without scientific notation.
Whether Historical is a genuine top-tier target or more of a mythological endgame carrot is something the community continues to debate, but the Ninja tier is absolutely real, documented, and worth every trillion it costs to chase.
SS Tier: Timeless and Godly
This is where earnings stop being measurable in billions and start climbing into the trillions. Timeless weapons are exceedingly rare drops that cost tens of billions just to purchase the corresponding case, and the income they generate at max level reflects that investment. A single maxed Rainbow Timeless weapon can produce over sixty billion per knife cycle on its own. Godly weapons, found in Godly Angel cases, sit above Timeless and deliver even more staggering returns.
The Star Spear, a Godly-tier weapon, starts at over one hundred million per knife at Level 1 and scales into the trillions when fully upgraded. Landing a Godly weapon through a gifted case or a lucky conveyor roll is one of the most impactful single events that can happen to your farm’s income.
The three weapons most worth targeting in this tier are:
- Rainbow Timeless – Costs around 67 billion to obtain but delivers 60+ billion per knife cycle at max.
- Godly Star Spear – Starts above 100 million at Level 1 and scales into multi-trillion daily output.
- Nin Sword (Ninja Godly) – Starts at 5 billion per knife at Level 1, making it one of the highest base-value weapons in the game.
S Tier: Secret, Limited, and Exclusive
Secret is the tier that most active players spend the bulk of their time chasing, and for good reason. Secret weapons produce income comfortably in the billions per knife cycle at max level, and Limited and Exclusive variants push even further. A Rainbow Secret weapon maxed out is worth hundreds of millions per knife, and some Limited weapons like the Night Fang or Limited Relic case drops begin pulling in figures that cross into the trillions of total daily earnings when combined across a full base.
Exclusive weapons from special cases sit at the very top of this tier, offering income that dwarfs anything in the tiers below and serving as a reliable foundation for players pushing toward the leaderboard.
Specific notable weapons in this tier include the Gaia’s Rose from Blood Secret cases, the classic sword variants pulled from Secret-level cases, and the murder knife line which, while less visually dramatic, scales impressively with upgrades.
A Tier: Blue Gem, Legendary, and Mythical
Blue Gem weapons are a major milestone. They are visually striking, earning rates jump into the hundreds of millions per cycle at max level, and they are rare enough that landing one on your conveyor feels like a genuine event. Legendary and Mythical knives sit alongside Blue Gem in this tier, with Mythical variants regularly hitting billions per cycle at high upgrade levels.
Specific weapons like the Clockwork Cleaver, which starts at several million per knife and scales into the tens of billions when fully maxed, are excellent examples of what this tier can produce. If your base is stacked with A Tier weapons, you are already comfortably in the mid-to-late game and generating income that would have felt impossible at the start. Do not sell these unless something from the tier above comes along to take the slot.
B Tier: Rainbow, Candy, and Emerald
Rainbow knives are the first tier where players start to feel genuinely powerful. A Rainbow Secret weapon, for instance, starts at values in the tens of millions per knife and can push well past one hundred million per cycle when maxed out. The visual design at this tier also becomes noticeably more impressive – Rainbow skins have a prismatic, shifting appearance that immediately signals to other players that you are no longer in the early game.
Candy and Emerald variants sit slightly below Rainbow in terms of raw earnings, but all three tiers are worth holding and upgrading aggressively once you have them. A Rainbow weapon in a full base will compound your income significantly faster than anything below it.
C Tier: Space, Blood, and Dark
This tier is where the game starts to feel like it is opening up. Space, Blood, and Dark knives carry base earnings in the hundreds of thousands to low millions per cycle, and upgrading them to Level 20 or beyond makes them genuinely solid mid-game contributors.
A Blood Diamond Sword, for example, is a Limited-tier weapon that earns in the tens of millions when fully upgraded – far beyond what early Golden knives can offer. These weapons are worth keeping and upgrading while you chase higher-tier cases, but treat them as placeholders rather than permanent residents in your base. They will eventually be outpaced.
D Tier: Rare and Golden
Rare and Golden knives represent a small but noticeable step up from the starting weapons. They begin generating a few thousand to tens of thousands per knife cycle and are perfectly serviceable during the first hour or two of active play. A Golden knife upgraded to Level 10 can be a reliable workhorse while you wait on better cases to open. That said, they become dead weight relatively quickly. Once your conveyor belt is upgraded and you start seeing Blood and Legendary cases appear more frequently, every Rare and Golden knife in your base should be cycled out without hesitation.
F Tier: Rusty and Normal
These are the knives you pull from basic starter cases right at the beginning of the game. Rusty and Normal tier weapons generate only a few hundred to a few thousand dollars per cycle even when upgraded, which makes them effectively useless once you have spent more than an hour in the game. They are worth keeping in the very early stages purely to fill your base slots and keep passive income flowing, but the moment you can replace them with anything better, they should go straight to the Sell Station. Their gem value when sold is minimal, and their upgrade cost is not worth investing in past the first few levels.
Final Verdict: What Should You Actually Keep?
The short answer is that anything below Rainbow tier should be rotated out as soon as you can replace it. Once you are in the Secret and above range, be very selective about what leaves your base. A Timeless or Godly weapon should never be sold under any circumstances unless you are replacing it with another weapon of the same tier or higher. Keep your base full, keep upgrading, and use the in-game Index to track what you still need to complete each tier.
The knife rankings in My Knife Farm are not just a flex – they are a direct map to your income ceiling. The higher up the chart your collection sits, the faster everything compounds.
