Comandante C40 MK4 vs MK3 Specs

Grinder Type

Edge: Tie

Both the Comandante C40 MK4 Nitro Blade and the Comandante C40 MK3 Manual Grinder use a blade grinding mechanism. This means they rely on spinning blades to chop beans rather than burrs to crush them. The MK4 is listed explicitly as a Blade grinder in its attributes. The MK3 also identifies as a Blade grinder. Both operate manually, requiring you to turn the handle yourself. Neither unit uses electric power or burr sets for grinding. The fundamental grinding action is identical in type for both models, relying on the Nitro blade technology for both.

Build Material

Edge: Comandante C40 MK3 Manual Grinder

The Comandante C40 MK3 Manual Grinder is constructed from 100% stainless steel, including its grinding parts. The product data highlights ultra-durable materials in steel with high edge retention and a Rockwell hardness of approximately 58. The Comandante C40 MK4 Nitro Blade Grinder features a copper mount, as indicated by its color and title. While the MK3 emphasizes its all-steel construction for durability, the MK4 introduces a copper component to its design. The remaining body materials for the MK4 are not specified in the provided data, so a full material comparison is limited to these known components.

Dimensions

Edge: Tie

The physical footprint of these grinders differs significantly. The Comandante C40 MK3 Manual Grinder measures 4 inches in width, 4 inches in height, and 8 inches in length. It weighs 8.01 ounces. In contrast, the Comandante C40 MK4 Nitro Blade Grinder is taller and narrower, standing 10 inches long, with a width of 2 inches and a height of 2.7 inches. The MK3 is more compact in height but wider, while the MK4 is taller and slimmer. These dimensions affect how each grinder fits on your counter or in your storage space.

Bean Capacity

Edge: Comandante C40 MK4 Nitro Blade Grinder

The product features note that both the brown glass jar and the clear polymer-glass jar included with the MK4 have this capacity.

Without data on the MK3's hopper or jar volume, you cannot determine if it holds more, less, or the same amount as the MK4's 40-gram capacity.

Power Source

Both grinders are manual devices. The Comandante C40 MK3 Manual Grinder is explicitly described as a manual coffee grinder with a manual power source. The Comandante C40 MK4 Nitro Blade Grinder also operates manually, as indicated by its design and the lack of any electric motor specifications in its data. You must provide the energy to grind the beans by turning the handle on both units. Neither model includes electric power, battery operation, or motorized assistance for the grinding process.
