Hattori Forums FH Series Petty (120mm and 150mm, Cocobolo Wood Handle)

Availability: Normally ships the same day

After years of the collaborative work with the Knife Forums "In the Kitchen" members and the premier knife maker, Mr.Ichiro Hattori, we are proud to introduce our first JCK Original, FH Series Hattori / Forums high end Chef's knives.                             

Hattori FH Series knife is produced in very small batches to ensure a high level of quality and performance. Every detail in design and manufacture has been taken into consideration from the special heat treat process, to the hand contoured handle and to the balance, ergonomics and profile of each knife.

The blade is made of VG-10 Cobalt Steel (HRC60 to 61). Even though it is simple appearance, we can feel the Hattori’s detailed works high level of craftsmanship from finely hand sharpened and polished blade.

For the handle material, Master Hattori chose the Cocobolo wood, which has a light brown color with unique & beautiful natural woodgrain textures.  Hattori's fine custom hand working process can be seen on its well hand contoured and perfect shaped handle.

Mr. Hattori believes that the comfortable and well balanced handles are as important as the good blades, so he pays a special attention to the details of not only for the outside looks, but also for the durability against crack and shrinkage that may happen in a long range of use on these natural materials. Before assembling and shaping the handle slabs, each selected wooden block is stabilized in the boiled wax for 3 hours, and then cut into two pieces for matching woodgrain patterns for both sides. In fact, when I first saw and gripped it in my hand, I felt something warmness and comfortable sense of touch with this hand shaped natural wood handle.

A mainstay of professional Western kitchens, the Petty knife is a small general-purpose knife used for peeling, shaping, and slicing fruits and vegetables, chopping herbs, and making garnishes. The compact size and relatively narrow blade of the Petty knife mean that it is very nimble and controllable, thus it is ideal for making precise cuts.

This knife comes with 50/50 double bevel edge geometry for both right and left handed use.  

For your information, Japanese Kitchen knives are generally designed for right hand use with a slightly thicker and rounded grinding on the right side blade and a less rounded (almost straight flat) grinding on the left side blade. However, both right and left hander can use the knives that have double bevel edge sharpened 50/50 without problems.  

We believe the quality and cutting performance of Japanese knives are the best in the world, and hope you enjoy fine craftsmanship and sharp edge with your new knife. With proper cares, every Japanese knife should be your special cooking partner for long times.



This is the Stainless steel blade kitchen knife that has a good rust resistance for easy maintenance. However, it may get rust, if kept in wet condition.

  • Please do not put the knife in the dishwasher machine for cleaning.
  • Please do not leave the knife in water or wet condition for long time.
  • After using, please hand wash the blade, bolster and handle thoroughly, and wipe it clean and dry with soft clothes, and keep it in dry place.
  • This is an extremely sharp knife. Please use special cares in using and storing it.
  • Unlike German made knives, Japanese knife blades are ground to thin cutting edge for sharper cutting and easier re-sharpening. Please protect the edge from hitting hard materials to avoid chipping or cracking.
  • Please do not use it to cut bone or frozen foods, any hard shell foods such as lobster and crab.
  • We recommend using Japanese whetstones to re-sharpen the knife, when it gets dull.

Hatori 150mm petty

One of the "go to" knives in my collection. If you don't already have 150mm petty you won't be disappointed with this one.

Beautiful knife!

I ordered a Hattori KF 150mm petty. I did a lot of research to find a petty knife--ultimately I decided to use the same brand as my much loved gyuyto (Hattori KF 210mm) I was maybe at looking into another knife brand (Nenox, Rysuen Blazen, Masamoto, Misono, Tojiro, etc) but I kept coming back to the price/performance of the Hattori KF. I'm not dissapointed. Knife is absolutely gorgeous. Fit and finish is right on point, very clean edges. Well balanced, nice and light. I know VG-10 isn't the darling of the knife steel world and has been supplanted by some other steels, but Hattori gets the most out of this steel. It might be slightly chippy but to be honest it's not a huge deal, take care of your knife, keep it sharp, use it correctly on proper materials, there is no reason this knife won't last you a lifetime. It is truly a fine piece of craftsmanship. I think, especially considering the price, this is hands down one of the best knife lines out there. There might be "better" knives out there (but really, such a subjective thing), there are definitely less expensive knives out there, but this level of quality craftsmanship at this price is hard to beat. I've ordered many knives from Japanesechefsknife.com over the years (they've improved the website much over the original) and they never dissapoint. Fast order processing, fast shipping (I'm in the US, ordered my knife on a Tuesday and it arrived on Saturday) and I paid a flat rate of $10. Most impressive--and it's been that way everytime. I've never had an issue with an order, but I imagine if I ever needed customer assistence they would resolve my issue quickly. They people are amazing! Everytime I've shopped at this website it has been a absolute pleasure. Thanks to everyone!

Excellent knives

I bought Hattori petty knives about decade ago both 120mm and 150mm, with lovely layers visible on the blades and insignia engraved on blades. I got the new JCK petty 120mm, as the old one got stolen. I found the new blade to be a bit smaller and without those visible extra layers seen on the blade. It feels light in hand and is well balanced. The wood handle is lovely and well made to fit my hand. The blade is super sharp and slicing fruits and vegetables is a pure pleasure. I would buy it again!!
