Comandante
Doesn't market plastic-free, but the C40's material choices land it there almost by default: stainless body, steel burrs, oak knob, glass catch jar. Its obsessions are metallurgy and avoiding aluminum, not plastic per se, so the near-plastic-free result reads as a byproduct of building a premium grinder rather than a stated mission. The "minimal-contact" rating points to the usual grinder caveat - small polymer parts in the mechanism - rather than plastic in the body itself.
How clear are their specs?
Detailed about the burr steel and body materials, but doesn't fully document the small internal components (bearings, axle bushings) where a grinder's remaining plastic typically hides.
