Features: Porlex JP-30 vs. Kyocera CM-45CF

Unlike electric grinders, hand-powered grinders are relatively lacking in features overall. However, when putting the Porlex JP-30 vs. Kyocera CM-45CF, it is clear that both devices do have some relatively desirable features amidst the overall simplicity of each device.

The three main features for the Porlex JP-30 are the stainless steel design, the ceramic conical burr and the adjustable grind settings on the conical burr. What you’ll find on the Porlex JP-30 is a very simple device that does not do anything beyond just grinding. It also features a 30-gram capacity, which makes it good for making around 16 ounces of coffee per grind.

The Kyocera CM-45CF features a noticeably smaller capacity for the catcher. It holds up to 20 grams of ground coffee.
The Kyocera device also features a primarily plastic design that allows the user to visually see how much coffee has been ground and to watch as the fresh grounds fall into the container.
The Kyocera CM-45CF also features a ceramic conical burr that is easy to clean, does not rust and does not alter the flavor of the ground beans.

Potential buyers will find that both devices have solid features. However, because it has a slightly larger container, the Porlex
JP-30 requires a bit less work to make larger amounts of coffee. As such, it emerges the winner or a comparison on features.

Build Quality: Porlex JP-30 vs. Kyocera CM-45CF

When making a Porlex JP-30 vs. Kyocera CM-45CF comparison on build quality, the focus comes down to the materials used. For the conical burr, both devices use a similar, hard and rust-proof ceramic material.

There is little indication that the ceramic used on either device is better or worse than the other. Indeed, both devices have relatively high ratings for the quality of their ceramic burr grinders. Ultimately, what must be focused on is the actual materials used outside of the burr.

The Porlex JP-30 goes for an all-stainless steel design. While this means that you cannot visually see how your grind is turning out without opening up the device, it also means that the strength of the device is noticeable. There is little fear of breaking the device, even if it is dropped.

However, the Porlex JP-30 does come apart more easily than the Kyocera CM-45CF, which could be a concern to some customers, particularly those that may be accident prone.

The Kyocera CM-45CF is primarily composed of hard plastic and glass. While the Porlex device only has plastic in one location (the round handle), the Kyocera device has is composed mostly of plastic. The plastic encases the burr and the hopper, as well as on the top and the bottom of the receiving container. The plastic for the contain is what may be of concern to some customers.

While a plastic container has little problem with breaking, it may be more prone to static buildup than the relatively static-free stainless steel found on the Porlex JP-30. While the plastic itself is high quality on this device, it is essentially a much cheaper device. Although the fact that being able to see what is in the container is a plus, overall the stainless steel design on the Porlex JP-30 offers a bit more physical strength to the overall design.
As such, a Kyocera CM-45CF vs Porlex JP-30 comparison on build quality goes to the Porlex JP-30

Grind Settings: Kyocera CM-45CF vs. Porlex JP-30

Hand grinders are unique in that adjusting the grind settings takes a bit more finesse than with an electric grinder. When making a Porlex JP-30 vs. Kyocera CM-45CF comparison for grind settings, one has to look at how the grind is adjusted and how many adjustments can be made.

The Kyocera CM-45CF essentially has two different grind settings: either a coarse-grained setting or a fine one. Grinding takes about 2 minutes on the Kyocera device. Positively, the burrs experience little to no “burr-wobble”, so the grind is very even and very smooth.

Meanwhile, the Porlex JP-30 also has two settings, one for fine and one for coarse. The adjustment is made by turning the adjustment wheel located near the burr. Grinding the full capacity (30 grams) on the Porlex JP-30 may likely take longer than for the Kyocera CM-45CF.

Both of these devices have similar grind settings and grinding functionality, making it effectively impossible to say whether one is better than the other. This means a Kyocera CM-45CF vs Porlex JP-30 comparison for grind settings ends in a tie.

Price: Porlex JP-30 vs. Kyocera CM-45CF

There is a clear price difference between the Porlex JP-30 and the Kyocera CM-45CF. A Porlex JP-30 vs. Kyocera CM-45CF comparison for price reveals that the Porlex has both a base price and a discounted price that is below that of the Kyocera device. The Porlex can be found listed for $69.99 and is often discounted.

For the Kyocera CM-45CF, the prices vary. The device has been discontinued, but can still be located in several different locations for anything from $100 to $150. Part of that expense is due to the fact that it is difficult to find.

If you compare it to the Kyocera CM-50CF, which sells for around $40, you’ll note that the two devices are relatively similar, but far apart in price (yet not the same quality as the CM-45CF).

Because the Porlex JP-30 is much easier to find, and therefore cheaper to obtain, it wins the comparison on price.

Aesthetics: Kyocera CM-45CF vs. Porlex JP-30

Both the Porlex JP-30 and the Kyocera CM-45CF have very different design approaches. A Porlex JP-30 vs. Kyocera CM-45CF matchup on aesthetics results in a debate on design principles.

Because both devices work essentially the same way and utilize the same internal mechanics, the outward delivery is what sells the device.

For the JP-30, Porlex has gone for a more utilitarian feel. The small, stainless steel casing is very attractive but casually simple. It does not offer any form of artistic take on grinder design. For some, the simplicity may be a huge selling point; for others, a let-down.

The Kyocera CM-45CF goes for a more open, curvy feeling in its design. Kyocera wants to draw your eyes downward toward the clear, plastic container and wants the grinding process to be as much a visual spectacle as it is a physical activity.

The overall question is, which one is a better design? If the two devices were similar, this would be easy. Unfortunately, their contrasting designs make it somewhat difficult to decide between the two. Aesthetically, both have their positive and negative traits, and a decision between the two would be a bit of a subjective one. The result of a comparison in aesthetics is a tie.

Overall winner: Porlex JP-30

Although Kyocera made a very solid device when they designed the CM-45CF, the Porlex JP-30 simply has the edge in some of the places that really matter.

The strong stainless steel design is hard to beat, and the slightly larger capacity makes it a bit more appealing for those grinding coffee for more than just themselves.

And indeed, the fact that Kyocera has discontinued the device is a negative toward it, as it has shot the price way up to what it could be.
The Porlex JP-30 offers a good mixture of grind strength, design and price, all in one very small cylindrical package.
