Konosuke Sumiiro Petty 150mm Purchase options

The petty is a versatile every day knife and when one looks and cuts as well as this you'll be wondering how you lived without it.

First Impressions

The Sumiiro was designed to be slightly taller at the heel and thicker at the spine than other Konosuke knives but without compromising on the performance you'd expect from the very hard SLD steel core.


This is undoubtely a stunning range. The black nashiji finish gives a nod to the black calligraphy ink used throughout the centuries in Japan while the core steel is polished to a fantastic mirror finish. 

It's then paired with a D shaped burnt chestnut handle that both compliments and contrasts the blade. It's a striking knife in every respect.

In Hand

Because of that taller and thicker profile the sumiiro is feels sturdy in hand but remains light, nimble and well balanced while the d-shaped handle has just a little texture in the finish to give a tactile finish in hand.


The SLD core steel takes and holds a great edge and has been hardened to a high level of 65HRC so it's going to last and perform very well. 

Ease of Care

SLD is close to being stainless so caring for it is pretty straightforward if you just follow the normal care instructions for any Japanese knife.

Our Verdict

We're delighted to be able to stock this range and there's little doubt these are high performance and quality knives in every respect and they're designed to perform and last.
