gbzkwemlgjqteht7kla9Most knives sold at retails currently are sharp at first slice but sacrifice durability for sharpness and won’t hold its sharpness for a long time. 

A great knife is sharp and also stay sharp for long time. The best balance between sharpness and durability actually depends on complicating match-ups of many factors; steel materials and hardness (also match-ups of heat treatment temperatures for hardness determination), edge angles, and blade thickness and so on.

From our long experience of knife production, we have been experimenting thousands of blade profiles and finally created an incredibly sharp and durable blade.

3 essential knives, Chef knife 20cm, Slicer knife 25cm and Petty knife 15cm, are in our collection. 

 

The blade material is clad steel of SG2, Powdered steel, for cutting core. It is the newer and better steel than VG-10, produced by the same alloy manufacturer in Japan.

 

Powder metallurgy 

Super fine (nano) powder of steel elements are compressed, heated and formed into ingots. This is a totally different alloy production process from the ordinary “melting process”. This special process enables a powered steel to contain much more key elements for better quality than melting-processed steel.

Better quality than VG-10 from the same alloy manufacturer 

VG-10 Japanese steel is currently used for the most of high quality kitchen knives in the market. Look around the other projects of successful kitchen knife on Indiegogo, they all use VG-10 stainless steel for their knife. 

SG2 powdered steel has been developed newly as the updated and better performance steel than VG-10 by the same manufacturer of VG-10 in Japan. 

SG2 actually contains 30% more of Carbon than VG-10 which decides steel hardness, 230% more of Molybdenum which contributes to anti-corrosion, and 570% more of Vanadium which contributes to sharpness durability.

Production difficulty 

However, it requires high techniques during knife production to draw a powder steel nature and its greatness. Therefore, not many manufacturers can carry this high level steel for their knives. 

Right now, only a few world major knife brands use this powder steel for their premium products that are sold at their highest price range, more than USD300 (MSRP).

Our in-house well-skilled craftsmen add the edge on the blade, every single piece by hand.

The traditional “Honbazuke” horning technique is applied. The edge is tapered to a 15 degree blade angle to make sure the knife is razor-sharp.

Hybrid of Western and Eastern

Blade shape is combination of Japanese and western cutlery culture. Japanese traditional “Kiritsuke” tip enables you to fillet fish and meat easily because the tip goes into sharply.

Blade width is more Western, it is wider so that your hand doesn’t touch the board when you cut. We know that many people complain that their hands touch the cutting board when they use Japanese knife because it is relatively narrower than western knives.

Not too thick, not too slim, gently curved handle is comfortable to grab. There are grooves on the handle so you can hook your fingers for perfect fit.

Handle material is Walnut-colored Pakkawood. Pakkawood is combination of wood material and resin compressed. It is better than natural wood handle in terms of shrinkage and durability. 

While natural wood handle tends to change color and its surface to become rough, pakkawood handle is more durable against those changes. It will even transform to fit to your palm gradually while you use the knife.

How we got here 

We have sketched tons of blade shapes and handle design to pursue our ideal knife and to maximize the used material features. We have made many of mock-ups to see if our idea actually corresponds with what we think the best. The last 10 months have been spent on testing the one we have ended up lastly and the knife has finally become what we cannot improve more.
