Manual Coffee Grinder – Knurled Grip, 5/6/7-Star 420 Steel Burr

At a Glance

A compact hand grinder for fresh coffee, one cup at a time. It pairs a CNC-cut 420 stainless steel burr with a knurled aluminum-alloy body, a stainless steel crank and a natural wood knob, and holds about 15-18 g of whole beans - enough for one cup of pour-over. Choose Black, Brown or Silver Gray, then pick the 5-Star, 6-Star or 7-Star burr that matches how you brew.

Which Burr Should I Choose?

All three burrs are CNC-cut 420 stainless steel and all of them adjust from fine to coarse. The star number refers to the burr's cutting-edge design: higher-star burrs are designed for finer, more even grounds.

Not sure? The 5-Star burr covers most everyday filter brewing. Results always depend on your beans, roast and recipe - see our coffee grind size chart for starting points.

Key Features

• Three burr options: 5-Star, 6-Star or 7-Star CNC-cut 420 stainless steel, each available in Black, Brown and Silver Gray.
• Fine-to-coarse adjustment: set the grind for anything from French press to moka pot, then fine-tune in small steps.
• Knurled grip: the knurled aluminum body gives your fingers something to hold, so it stays secure in your hand while you crank.
• Stainless steel crank, natural wood knob: a smooth, comfortable turn.
• Removable grounds cup: pour the grounds straight into your brewer.
• No power needed: no battery or outlet - at home, at the office or on the road.

How to Use

1. Add up to about 15-18 g of whole beans.
2. Set the grind - start in the middle of the range for pour-over.
3. Hold the body steady and turn the crank until it spins freely.
4. Remove the lower cup and pour the grounds into your brewer. Brew, taste, then go finer or coarser in small steps.

Care

After use, brush out loose grounds with a dry, soft brush. Do not immerse the grinder or rinse the burr assembly; if any part gets wet, let it dry completely before reassembling. More tips in our coffee grinder cleaning guide.

FAQ

Which burr should I choose?

For pour-over, drip and French press, choose 5-Star. For AeroPress, moka pot and finer pour-over, choose 6-Star. If you mainly want very fine, espresso-style grinds, choose 7-Star. Every burr still adjusts across the full fine-to-coarse range.

How is this different from your other 5/6/7-Star manual grinder?

This model has a knurled body and comes in Black, Brown or Silver Gray. Prefer a textured band around the middle, or a Champagne Gold finish? See our center-grip manual coffee grinder. Both hold about 15-18 g and offer the same three burr options.

Can I choose any burr with any color?

Yes. Black, Brown and Silver Gray are each available with 5-Star, 6-Star and 7-Star burrs.

Can I change the grind size?

Yes. Adjust toward fine or coarse, make small changes and test with your own beans and brewer.

How much coffee does it hold?

About 15-18 g of whole beans, enough for one cup of pour-over. Actual fill varies with bean size and roast.

Is it good for travel?

Yes. It is compact and needs no power, so it packs easily for trips, camping or the office.
