Hatsukokoro HAP40 Petty 120mm Purchase options

Like its counterparts in the range, this petty is both light and nimble and a perfect size for the more intricate jobs where precision and an excellent edge are always needed.

First Impressions

Sharp out of the box and there's definitely scope to pretty easily get a truly screaming sharp edge with a little work on a stone or with a ceramic rod. 

The blade shape is stamped and then sharpened and finished by hand to ensure a consistent and quality finish across the knives.

Beauty

This is perhaps not a range you're going to buy based entirely on its looks. It's a classic polished finish with a visually interesting and consistent grind exposing the HAP40 steel core and the Kanji is 初心 meaning 初 (innocent) 心 (spirit).

In Hand

The entire range is impressively lightweight and overall they're pretty thin all the way along the spine and taper nicely. The heel of the knife is comfortable but it would be nice if it were just a little more rounded and finished around the edges for added comfort.

Durability

Made by Hitachi Metals Limited, HAP40 is a steel that is well regarded for its hardness and the treatment of this range is around 64-65 HRC so edge retention is excellent and these are durable knives when looked after correctly.

The durability and edge retention is the big feature of this range.

Ease of Care

These are a semi stainless knife so we'd recommend caring for them following the normal rinse and dry routine but it would also be worth applying drop or two of camellia oil from time to time as HAP40 steel has a chromium content but it's worth the extra care for the edge retention properties it offers.

Our Verdict

This range is an interesting combination of stamped blade production and then sharpened and the handles fitted by hand.

There's a great level of consistency across the knives in the range and for the most part, you're paying for the HAP40 steel which is going to take and retain an excellent edge and offers a high level of durability despite it's thin profile.

Overall, an impressively light but solid knife that's going to last.
