Super performance and value for money, the Kaishin santoku is a great all rounder for any kitchen.

First Impressions

The "Kaishin" ranges (in various steels and finishes) make an excellent first impression, they're ground very thin behind the edge and this gives very good cutting performance right out of the box and it's clear the attention to detail and quality of finish is something Nakamura Hamono care deeply about.


At this price point, it's great to see knives finished to this standard with a kurouchi finish across the soft iron cladding that gives way to a very nicely done misty kasumi running down to the core steel.

The oval cherry wood handle offsets the dark blade finish nicely and overall it's a great looking range of knives.

In Hand

The thicker spine above the heel has a nice feel and balance on the larger knives while the shorter petty options are well balanced and robust and all feel nimble in hand offset by the reasonably lightweight oval handles.


The Blue #2 core steel is heat treated to around 62-63HRC which we always find is a great middle ground offering durability and robustness without feeling fragile but also offering a good level of edge retention. 

Ease of Care

Carbon steel clad in soft iron is reactive and will devleop a lovely patina along the edge with use. Blue #2 is a common and popular choice for many because it offers good performance levels while being easy to sharpen and care for. 

For long term use and care, follow our carbon steel care tips and look after your blade with a carbon steel care kit.

Our Verdict

We're big fans of Nakamura Hamono knives, and despite them being a relatively young company it's evident across all their ranges that the focus on quality finishes and edge performance is something they take very seriously. 

The Blue #2 range is excellent value for money, given the standard of the finish, the sharpness right out of the box and overall performance these are a range of knives that would be an excellent first knife purchase if you are looking to get into the world of Japanese carbon steels or if you're looking to add another knife to your collection without breaking the bank. 

Highly recommended.
