Naniwa Gouken Kagayaki 400 - 1000 Grit Sharpening StoneThe Naniwa Gouken line represent a new product offering philosophy from Naniwa, one of the most reputable sharpening stone manufacturers. For as long as I could remember, the Naniwa Chosera line represents the holy grail of sharpening stones for kitchen knives: very fast cutting power, slow dishing and most importantly offering a very very gentle sharpening feedback that was not seen in other stones.

The Naniwa Gouken line represent a new product offering philosophy from Naniwa, one of the most reputable sharpening stone manufacturers.

For as long as I could remember, the Naniwa Chosera line represents the holy-grail of sharpening stones for kitchen knives: very fast cutting power, slow dishing and most importantly offering a very very gentle sharpening feedback that was not seen in other stones. The stone is huge in size (25mm thick, with the 10K over 30mm), and is mounted on a traditional base, and there is a free HUGE Nagura (cleaning stone) comes with the package

(The classic Naniwa Chosera is too big to ship)

If you ask me, what is the problem with the Chosera line? Well the single biggest problem for us, the vendors, is that the stone is simply too big to ship: at 210x70x25mm, the stone is too heavy and to be honest, even in commercially environment like the store, we don’t wear out a Chosera that quick, for an average user it is even less likely to wear one out in a reasonable time. The included nargura doesn’t help either as it contribute to a lot of weight with virtually no use at all (most of us use diamond plates or natural naguras anyway).

At over 2KG in shipping weight, the cost of international shipping becomes prohibitive. If we want to make sure the package lands safely (a cracked stone for an international order is a DISASTER!), a lot of padding must be added, resulting in the volumetric weight sometimes exceeding 3KG.

Plus, so many customers asked the question of “Do you offer the Chosera without base?”

 

The Gouken

To adjust the above-mentioned problems, the Gouken line was introduced. Currently there are two sub-labels under the Gouken branding. The Arata and Kagayaki.

 

The Kagayaki

 

The Kagayaki is very budget friendly. My experience with the Kagayaki is also very good. Based on the popular “Naniwa Super Stone”, the Kagayaki is making it slightly harder therefore less dishing, at 10mm thick, it is very easy to carry around and a standard carrying box can fit two Kagayaki stones. I much prefer that Kagayaki over the similar-sized Shapton Glass Stone because:

1. Overall both the Shpton Glass and the Naniwa Kagayaki perform similarly, the Kagayaki has a better feedback.

2. They are the same in terms of size, however the Glass Stone has a merely 5mm of abrasive (the rest is the GLASS). You keep the stone flat by lapping it, not by having a glass at the back.

3. The Kagayaki is cheaper compared to the Glass Stone, and taking the abrasive thickness into account, the Kagayaki offers a much better value.

Great Toy!
Color: Tropical Pack
These are great! I bought last Christmas for our pup- a 17 lb Aussie doodle. She’s pretty rough on toys. Usually pulls the stuffing right out in a few days. But these have lasted all year. Came back to buy her 2 new “flavors” to put under the tree.

Cute toy, not a loud squeak
Color: Original Pack
The toy is a good size for medium to large dogs. It's very hard to squeak it but it's fairly durable and super quirky!

Cute toy and well made
These are very cute and so far my dog has not destroyed them and he’s a very aggressive chewer. They are great quality. The colors are vibrant. Rocky loves the squeaker. They're light weight and the perfect size . He enjoys playing with them. We like to take them when he’s not looking and throw them to watch him go fetch them.
