7. Retro

Kicking off our list of the best MM2 Summer Event knives is the Retro knife. This Uncommon knife has a funky design with colorful patterns and shapes in pink, green, red, blue, and yellow. It also features a black grip with a gold-colored guard, which goes well with the other colors.

You can get the Retro knife from the 2025 Summer Box or by trading with other players. The Summer Box costs 800 Beach Balls or 1 Summer Key, and since Retro is an Uncommon knife, there is a 15% chance of pulling it. The trading value of this knife is not fixed yet, so the best way to get it is through the Summer Box.

6. Tropical

Next up is the Tropical knife, a Rare knife. Its design features a Macaw, a Parrot, and a Sun Conure sitting on a tree in a rainforest background. The primary color of the knife is green, while the birds add bright colors that complement the overall look. The handle is a darker shade of green with a branch-like design, making it a great choice for players who like beautiful color combinations.

You can unlock the Tropical knife from the battle pass at Tier 21 after collecting 16,000 Beach Balls or by trading with other players. Since it is a Rare knife, it does not have high demand in the trading market and does not hold a fixed value. The easiest way to get it is by unlocking it through the battle pass.

5. Pop Art

Another Rare but very unique knife from the 2025 Summer Event is the Pop Art knife. It features vibrant colors with golden stars, pink polka dots, and a refreshing pink bubble tea above the handle. The best part about this knife is the cartoon of Nikilis, the game’s creator, yelling “It’s Summer” in Japanese. This knife also has a partner gun that shares the same cartoon and color pattern.

You can unlock the Pop Art knife from the battle pass at Tier 19 by collecting 14,400 Beach Balls or by trading with other players. According to Supreme Values, it has a trade value of 3 and a demand of 2. The best option is to unlock it through the battle pass.

4. Aquarium

Now entering the Legendary rarity is the Aquarium knife. This knife is designed like an aquarium, with water covering the entire blade and various fish, coral species, and other underwater objects inside it. There is also an Aquarium gun with the same design, completing the Aquarium set.

You can get the Aquarium knife either from the 2025 Summer Box or through trading. Since it is a Legendary item, it has a drop rate of just 5%. The knife does not have reliable trading values yet, so the best way to obtain it is through the Summer Box.

3. Sunset

At number 3 on the best knives in MM2 Summer Event is the Sunset knife. It is a Godly knife and primarily features shades of indigo and yellow to resemble a sunset, with cloud-like textures all around the knife, completing the look. This knife comes with an FX tag—the sun glows neon yellow, and the knife itself looks even better in the dark. It also has a matching gun called the Sunrise, which shares the same theme.

You can get the Sunset knife either by reaching Tier 25 on the battle pass and spending 90,000 Beach Balls or through trading with other players. The Sunset knife has a demand of 4 and a value of 275 according to Supreme Values, while MM2V lists its value at 400.

2. Chroma Sunset

The second-best MM2 knife in the Summer Event is something you might have already guessed: the Chroma Sunset. This is also a Godly knife and shares the same theme as the Sunset, except there is a very rare chance of unlocking this chroma version instead of the normal knife. The overall concept is the same as the Sunset, but it has rainbow colors that constantly shift, just like most other chroma versions in the game.

There is a 2% chance to get the Chroma Sunset knife instead of the normal variant at Tier 25 of the battle pass after spending 90,000 Beach Balls. The knife has a demand of 5 and is currently valued at 3,500 by both Supreme Values and MM2V.

1. Synthwave

Finally, the best knife in the Summer Event 2025 is the Synthwave knife. This knife is a special one; when you first obtain it, it starts off as a Rare knife, and as you gain more EXP, the knife evolves, changing its appearance and rarity.

• At 0 EXP, the knife has the default knife mesh with a black body and blue and purple patterns.

• At 36,000 EXP, the knife becomes Legendary. It keeps the same shape and colors, but gains more vibrant and glowing effects.

• At 216,000 EXP, the knife becomes Godly. It transforms into a broken sword while keeping the same color combinations.

• At 864,000 EXP, the knife becomes Ancient. It evolves into a scythe with the same color combinations and additional patterns.

Getting this knife is simple, as you only need to purchase the Synthwave Gamepass. However, evolving it into the final version requires a lot of grinding. The Synthwave knife is not tradable. This wraps up the list of the best knives in Murder Mystery 2 Summer Event and all the methods to get them. You can grind through the battle pass or open boxes, trade with other players if you find a good deal, or get them instantly without any hassle through U7BUY, as mentioned
