Materials & Craftsmanship

Crafted from a premium blend of walnut wood, ABS, silicone, stainless steel, and zinc alloy, the MHW-3BOMBER Knock Box is built for longevity and daily use. The walnut body not only provides a warm, natural look but also ensures high density and durability. Expect natural variations such as tree scars and mineral lines—these are not flaws, but marks of authenticity that make each knock box unique. The silicone pads and knock bar cushion your portafilter and reduce wear, while the stainless steel and zinc alloy elements add structural strength and a touch of modern sophistication.

How to Use for Maximum Efficiency

• Knock Out with Confidence: After pulling your shot, tap the portafilter against the silicone knock bar to easily eject the puck—no mess, no fuss.
• Organize Your Tools: Store your puck screen, extra baskets, WDT tool, or tamper in the magnetic side drawer for quick access during your workflow.
• Easy Cleanup: Detach the silicone pad and knock bar for thorough cleaning. The entire box is designed for fast disassembly and reassembly.
