Shigeki Tanaka KU Blue 2

Sanmai - Soft Iron Clad Kurouchi Blue 2 / Aogami #2 / Carbon Miki, Japan

Forget the polish – Shigeki Tanaka's Blue #2 line is where real cutting happens. This is one of Tanaka's long-standing signature series, beloved for getting the fundamentals brutally right: a perfect profiletrue workhorse grind geometry, and outstanding cutting feel that powers through prep.

Yeah, the finish is rustic. It's not a show pony. But that's the point. Tanaka pours his skill where it counts: masterfully heat-treating Blue #2 steel. This gives you serious edge retention combined with solid impact resistance – a blade built for the long haul.

This is the definition of a workhorse grind: thicker spine, robust edge, built to take real impact and keep slicing. No delicate lasers here – just reliable, day-in, day-out performance.

Heads up: It's carbon steel with iron cladding. That legendary toughness comes with responsibility – it wants to rust. Seriously, just keep it dry between tasks and after washing. It demands respect, but rewards you with incredible cutting power.

If you want a knife that feels solid in handpowers through ingredients, and prioritizes pure, durable performance over fancy finishes, this Tanaka Blue #2 is your true carbon workhorse. Pay for the grind, not the gloss – just remember the towel!
