A Brief History of Brass Knuckles Cart Vapes

Brass Knuckles started strong when vape pens were exploding in popularity. They built their reputation around easy-to-use batteries and carts that looked as good as they performed. Of course, the brand’s ride wasn’t totally smooth. They faced challenges related to product authenticity and quality control a few years ago, and that definitely shook up their standing for a bit. 

Since then, they’ve made serious improvements to get back on track. Brass Knuckles has refocused on quality assurance and ensuring every battery and cart meets modern expectations. That commitment has helped them rebuild trust with both new and returning customers.

Brass Knuckles made its mark early with reliable hardware and recognizable branding. Even when the industry shifted and new names popped up, they stayed on a lot of customers’ radars. In 2025, we’re seeing a few big reasons why Brass Knuckles is still talked about:

• They stick to simple, durable designs.
• They support 510-thread cartridges, keeping things universal.
• Their batteries now offer adjustable voltage, giving you more control.

The Calm Leaf community looks for products that balance quality with affordability, and Brass Knuckles fits that need well. It's one reason why they remain a popular choice when customers shop for vaporizers today.
