The Kai Seki Magoroku Santoku has a mono steel construction. The steel is stainless and is very durable. You can see the knife series on the right side, the other side has the Kai logo and information on where the knife is made. The blade length is 165mm measured from the heel towards the tip. The knife thickness is 1.8mm with no spine taper.
Knife Handle & Comfort
The Kai Seki Magoroku Santoku handle has a half bolstered westernized handle. It is a full tang handle that is inserted into a laminated wooden handle and held together by 3 rivets.
The handle has nice contours and is comfortable to hold for those with a small to medium hand size.
If you have a large hand size the handle might feel a bit small and will not fill your palms, this can cause some cramps and discomfort if you use the knife for a prolonged period.
The handle is water-resistant and is very nicely made with a half bolster for better gripping comfort at the neck area of the knife. The handle has a slight odor out of the box which will go away over time.
The Santoku profile of the Kai Seki Magoroku Santoku has an aggressive curve upwards which is great for rocking. While you can still use a forward cutting motion you have to angle it more so it is not ideal to go for a forward chopping motion. Due to the aggressive curve and the short length of the Santoku, you have to add more travel distance to cut certain food completely.
Recommended Gripping Style & Balance Point
I recommend a pinch grip for a Santoku knife where the thumb and index finger determine the balance point. The point of balance of Kai Seki Magoroku Santoku is exactly at the half bolster. The diagonal bolster also makes it comfortable to pinch at that area. For more precise tip work the fingertip is also comfortable to hold due to the contours. The knife will be front-heavy with a fingertip grip assisting you with your tip work.
Core Material & Rockwell Hardness
The exact steel type and Rockwell hardness have not been specified. But it is stainless steel that is durable and tough. The Rockwell hardness on my review sample is around 56.
Sharpness & Edge retention
The out of the box sharpness is decent and the knife is sharpened at around a 15-degree angle per side. The Kai Seki Magoroku Santoku has no spine taper. The knife is also quite thin giving you a smoother cutting performance. However, even with the thin knife, you will notice some slight wedging on denser food like a carrot. The edge retention is around 1 or 2 months with regular honing in between before needing a whetstone sharpening session.
Key Takeaway & Recommendation
The Kai Seki Magoroku Santoku from the Imayo series is a solid budget knife that checks everything of what a knife should have. A nice balance point with the diagonal bolster for added comfort. The handle is on the smaller side suitable for those with a small to medium hand size. The knife profile is on the more curved side and may not be ideal for those that want to do a forward cutting motion. The knife is catered for the home cooks and housewives it is a worry-free knife that can handle some abuse. You will notice that the edge retention is not great and therefore a frequent hone on a honing rod is needed. If you want a knife with longer edge retention then you may want to look at the other series that Kai provides since the steel that they use on the Imayo series is on the softer side.
Maintenance & Care
There are slight gaps around the bolster so make sure it is dry before storing.
Due to the gaps around the bolster, it is advisable to dry the knife entirely since the gaps can be a starting point for rust to form. Due to the softer blade, you most likely need to hone the knife once a week and add a sharpening session every month or two.
I N F O:
The Seki Magoroku line has different series and in the west, they have other options available each series differs a bit from Rockwell hardness to aesthetic and profile. For a better Rockwell hardness, the Kai ”Shun” series is the more premium option.
