It’s not usually I get excited by sure improvements within the guide, hand cranked grinder world.
Positive, there’s been some incredible improvements in that area ever for the reason that Porlex Mini got here alongside 13 years in the past and actually shook the area up. Every thing from intricate burr geometry designs, to extremely exact 8um changes on grind settings, to triple and even quadruple bearing mounts for rock stable burr rotations, and even issues like hybrid grinders, doing double responsibility as electrical grinders for dwelling use, and guide when out on the go.
However as superb and value-rich the hand grinder market has gotten, I nonetheless get my kicks from the improvements within the motorized grinder world, for essentially the most half. Then I noticed a brand new guide grinder from the feisty upstart firm with the horrible branding identify – MHW-3Bomber – that truly acquired me fairly excited. As a result of this new grinder has a wildly attention-grabbing innovation: it has a sieve and shaker system to separate out fines out of your grind. Constructed proper into the grinder.
That’s a little bit of a sport changer for anybody who occurs to love no-paper filtration strategies for brew espresso. When you’re a Kone consumer, use metallic filters to your AeroPress, like utilizing the Espro Bloom, or are a press pot aficionado, you in all probability know utilizing a sieve system just like the Kruve sieve can enhance the cup of espresso fairly a bit, and scale back the sludge within the completed cup. Drawback is, the Kruve begins at $100 (IMO nonetheless effectively definitely worth the funding!) and may go as much as $200 or extra in case you go for many of the sieve choices.
However at this time, we now have the MHW-3Bomber Blade R3 guide grinder, with a in-built sieve system. And in lots of instances, the complete grinder with sieves prices lower than the Kruve starter system. Proper now the Blade R3 Grinder is $90 on Amazon (when you apply the ten% off coupon). So is it definitely worth the cash?
Effectively, this isn’t our formal evaluation, however your TL:DR is: heck sure!
Heck, I even purchased one alone, I used to be so intrigued (since then, MHW-3Bomber has additionally despatched us a check unit, so I now have two to check, aspect by aspect!)
The Blade R3 Grinder
Earlier than I even get to the sieving system, which has advantages and disadvantages, let me briefly cowl the remainder of the Blade R3 from MHW-3Bomber. This can be very effectively made, prime to backside. It definitely doesn’t really feel like a $90 grinder; simply in really feel, match and end, it matches effectively with $150 to $200 guide grinders on the market. Your complete development is metallic, and the whole lot matches along with exact engineering.
The Blade R3 has an exterior click on dial for adjusting the grind fineness, and every particular person click on adjusts within the burr vertical motion by 16 microns. That places it on par with some 1zpresso grinders, and and has higher grind choice efficiency than the Commandante and different grinders presently on market. The grind quantity indicators are very simple to learn, and the grinder comes zeroed out from the manufacturing unit. The grinder can be calibrated: it has the same spindle / locking nut mechanism to some 1zpresso grinders.
On visible inspection, 3Bomber’s “customized” heptagonal (7 bladed) 48mm conical burr seems similar to current 1zpresso flagship grinders’ burrs, however not the present Ok-Extremely, J-Extremely or X-Extremely from 1zpresso, all of that are model new designs. As soon as I get right down to the total Snapshot Evaluate for the Blade R3, I’ll give the burrs a a lot nearer look. For now, right here’s what they appear like.
The burr stack can also be much like the earlier gen 1zpresso guide grinders: the thick spindle (electrical drill suitable in keeping with the producer!) is completely hooked up to a backside block plate. The internal burr slides down the spindle and locks into place on the block plate through a mounting bolt. The spring sits above it. On this case, 3Bomber’s spring is so much longer than these discovered on 1zpresso fashions.
I ought to be aware, 1zpresso did away with the underside block plates on their most up-to-date grinders, and as a substitute, hard-attach the internal cone burr on to the spindle. They stated this reduces static points with their grinder. Right here’s what the 3Bomber setup seems like:
The crank arm is similar to these discovered on the Commandante, older 1zpresso and Kin Grinders, however has an extended attain. It’s longer than the present gen 1zpresso J-Extremely deal with, for instance. The deal with is beefy, made from wooden and a bit completely different in form in comparison with different grinders I’ve right here.The mounting cap for the crank arm is made from metallic and secures very effectively on prime of the grinder.
Your complete grinder could be disassembled with out instruments (besides the adjustment exterior dial). That is incredible for deep cleansing. Right here’s the grinder, fully disassembled, with all its components:
The grinder is lengthy, with a great grip portion that’s notably elongated. The catch cup is held in place by a gazillion magnets, and holds on even tighter than the present technology 1zpresso grinders, which is saying one thing as a result of the Ok-Extremely, J-Extremely and X-Extremely’s catch cups are held on fairly firmly in comparison with earlier technology fashions.
Now to the catch cup itself. It’s a 4 half affair: the principle catch cup, a screw on base, a sieve disk, and there’s additionally a magnetized lid to make use of when shaking the catch cup filled with grinds. The Blade R3 comes with 5 sieves, in micron dimension holes of 300, 400, 500, 600, and 850. As talked about there’s a gazillion magnets (every part has 24 uncommon earth magnets put in).
The catch cup, with outer magnets, and internal display put in.
The sieve put in within the backside of the catch cup (however the backside screw plate isn’t hooked up).
One of many sieves, displaying the outlet sample.

There’s one actually bizarre factor in regards to the Blade R3 it is best to be aware if shopping for: the capability of the grinder is barely 20g in case you are utilizing the in-built sieve system. That is bizarre as a result of the grind chamber and “hopper” for beans above the reducing blades can maintain much more espresso: a minimum of 30g if no more. However the catch cup, a minimum of when the sieves are put in, will prime out at about 22-23g which I don’t advocate doing as a result of that tops out the catch cup. If the catch cup is full to the brim, shaking the espresso for the sieving impact received’t work very effectively. You want some headspace in there, so 18-20g is the max espresso it is best to have in there when utilizing the sieve.
After all, you can use the catch cup with none sieve put in, and the capability of it will increase to round 25-30g, practically matching the hopper up prime.
Utilizing the MHW-3Bomber Blade R3 Grinder
At present we’re testing loads of guide grinders: three 1zpresso fashions, the most recent Timemore exterior adjustment grinder, two from Staresso (together with one that’s rechargeable!), and a Kin Grinder. For the previous 45 days, about 80% of the espresso and low brewed in my lab area and at dwelling has come from guide grinders. I point out this as a result of I’ve been capable of do loads of aspect by aspect comparisons with loads of completely different manufacturers.
Once more, stressing this isn’t my formal evaluation: the MHW-3Bomber Blade R3 is holding its personal. It isn’t matching the king of espresso grinders – the J-Extremely from 1zpresso – on general espresso high quality, however it’s on par with the dearer Timemore and Ok-Extremely. Contemplating the grinder is barely $90, that’s severely spectacular.
The most important challenge I’ve had with the Blade R3 is static. The combo of supplies (metal, aluminum, a number of magnets, and the metal sieve disks) plus the block-plate on the backside of the burr set all appear to create a bit extra static than I’m getting from the present gen 1zpresso fashions and the brand new Timemore. RDT’ing the dose helps a bit, however it’s nonetheless there, and that moisture, as minute as it’s, can also be evidenced within the catch cup, with some grounds sticking stubbornly to the angled edge the place the sieve meets the aspect partitions of the catch cup.
When it comes to grinding “motion”, it’s clean and really low resistance. That is apparent due to the lengthy crank arm design. The spindle is held in place with three anchor bearings, making the rotation of the burr rock regular and even. And since the spindle may be very thick, utilizing an electrical drill with this grinder, in case you observe Jim Hoffmann’s recommendation, is definitely fantastic (you shouldn’t use an electrical drill on extra slender gauge spindle grinders just like the Timemore sequence).
Every thing matches collectively effectively. The grind markings are extraordinarily simple to learn in most mild situations. The catch cup is held on so tightly it’s truly a bit troublesome to take away, however there must be virtually no fear about by chance knocking it off and spraying espresso all over the place when you function the grinder.
Briefly, this can be a very effectively constructed, effectively engineered, precision instrument.
Sieving
I didn’t anticipate the sieves to work all that effectively. In any case, the floor space of the sieves is like 1/sixth the floor space of the Kruve Sifter sieves. However in follow, it truly works fairly effectively, eradicating about .5g of fines from an 18g dose floor for pour over and utilizing the 500um sieve, in my restricted testing.
It even works higher for press pot. I set the grinder up for 1200um particle sizes, used the 850um sieve, and for each 15g I floor (I might grind two batches to hopefully get 28g of espresso to make use of), it will sieve out about .75g of fines. This resulted in so much cleaner cups general from my press pot brews. Consider you’ll should grind about 8-10% extra espresso to take the sieving quantity into consideration.
The method is that this: set up the sieve of your selection, set the grinder to your set grind degree, and grind the espresso. As soon as accomplished, take away the catch cup, put the catch cup lid on it, and begin shaking the bejeebus out of the container. Aspect to aspect motions, knock motions, up and down. Do that for a few minute. Then pour out the espresso from the catch cup. In a while, unscrew the underside plate, and witness all of the fines you sieved out. Magic.
There’s the aforementioned drawback with static. I’ve additionally famous espresso would get caught in crevices and edges within the grinder, making it a bit onerous to get all of the usable espresso out
Oh, yet another factor: 3Bomber, of their promo literature, says the act of shaking the container is calming and focusing, which has well being advantages for you. Particularly: “sieving additionally relieves your stress; get pleasure from it within the current second!” Extra magic? 🙂
Ought to You Purchase One
If all you do is espresso along with your guide grinder, as a substitute go together with the 1zpresso J-Extremely, which might be the finest guide espresso grinder you should purchase at this time. With the MHW-3Bomber Blade R3, the sieves received’t provide you with a lot profit for espresso, and all that point shaking the grinds catch container will stale the espresso.
Additionally, if you would like your guide grinder to crank out giant (30g+ batches of espresso in a single go, the Blade R3 won’t be for you.
However if you would like an all objective grinder that provides you good worth and wonderful development for below $100, then heck sure it is best to take into account this one.
When you choose utilizing metallic filters (or extremely uncommon, luxurious all ceramic mesh filters boo yah!) in your pour over, or metallic filters along with your AeroPress, or are an enormous press pot fan, this grinder may be the only option for you, due to the sieving system, in-built. The most important drawbacks are a) the low capability and b) the static. I did be aware there was much less static when I didn’t use the sieves in place, so I’m fairly certain the combo of metals contributes a tad to this.
Proper now, the MHW-3Bomber Blade R3 is listed for $100 on Amazon, with a ten% off coupon out there, making it $90. That’s a killer discount for this system. We’re engaged on a full Snapshot evaluation for this grinder and a number of other different guide grinders, coming quickly.
