Don't forget these...
Allow us to help since everyone always asks this question. No Shigeki Tanaka is not related to Yoshikazu Tanaka. They are different smiths working out of different cities - Meki city for Shigeki-san - with different approaches to knives. Shigeki Tanaka knives are easily recognizable as they exude more of a workhorse appearance, and have remarkable performance.
The core of this series is blue (aogami) #2 steel, a steel which lends itself to being tougher than blue #1, qualities which work very well for a smith who likes to make more robust knives. 17 layers of Damascus just above the cutting edge with a kurouchi that is more gunmetal in look than the classic black you are used to seeing. Very attractive knives at this price point, and qualities that lend themselves well to those that don't want to worry about owning too delicate a knife.
Ah we have finally arrived at the conundrum with no end, the 240mm gyuto. Those who love a 240mm gyuto will without fail and without any subtlety express their obsession with this particular length of gyuto. With 30mm extra than the typical 210mm gyuto, a 240mm gyuto is a great knife for those with bigger hands, larger kitchens, bigger tasks, larger... you get the point!
A gyuto is already a versatile knife style, at 240mm, you gain even more versatility. And don't you dare tell someone who loves 240mm gyutos that it's too large to slice garlic, because they'll prove you wrong.
