Overview
The Knock Feld47 steps up to larger 47mm Italmill conical burrs for improved grinding speed and quality. The bigger burrs require fewer turns per gram, making the grinding process faster and easier. The stepless adjustment provides excellent control for espresso, and the overall build quality is refined. The Feld47 represents Knock premium offering, competing with established names like Kinu and Commandante at a more accessible price point. An excellent choice for the hand grinding enthusiast who values quality without brand premium.

At $180, the Knock Feld47 is aimed at home baristas seeking a solid grinder without a premium price tag. Key workflow features include single-dose design (no hopper needed) and stepless grind adjustment for infinite precision. As a hand grinder, it's completely silent, portable, and gives you a meditative morning ritual.
The Knock Feld47 is weighing 0.7 kg, manufactured in United Kingdom. Its footprint measures 55 x 55 x 200 mm (W×D×H).

Our Verdict
The Knock Feld47 is a hand grinder, which means it trades speed and convenience for portability, silence, and often better value per dollar of grind quality. In the $100–$250 range, hand grinders can match or exceed electric grinders costing twice as much in grind quality. This is the sweet spot for serious home baristas who don't mind the manual effort. If your daily routine involves 1-2 drinks and you enjoy a mindful morning ritual, this is an excellent option. For larger households or back-to-back drinks, consider an electric alternative.
