Summary
An FC61 stainless paring knife, ice-hardened to 61 HRC and honed to an acute 9.5-12° edge, handcrafted in Seki, Japan. Check the edge care before you buy: the thin blade is more fragile than a Western parer, and the knife is hand-wash only.
Strengths
- The comparatively long handle gives more to grip for in-hand paring, and the octagon shape works for either hand and suits larger hands.
- Owners on the maker’s page call the knife light and well balanced through extended peeling work.
- It arrives very sharp out of the box, and owners say the edge is easy to maintain.
- Owners report the 61 HRC blade resists chipping and scratching in regular use.
- It shares the FC61 steel, 61 HRC hardness and Honbazuke edge of the rest of the Koh line, at the bottom of Miyabi’s parer pricing.
- Zwilling’s lifetime limited warranty replaces a defective knife for as long as the original owner has it.
Weaknesses
- The 9.5-12° edge is more prone to damage from misuse such as bones, frozen food or the dishwasher than a Western parer.
- The thin blade profile is delicate by design, so the knife asks for careful handling and hand washing.
- No independent lab test of this exact model exists, so the maker’s sharpness and chip-resistance claims are unverified.
- Owner evidence is one small review pool on the maker’s own page; forums could not be read, so the absence of complaints proves little.
- Keeping the edge means a whetstone or paid sharpening, and a badly damaged edge means replacement: there are no user-serviceable parts.
- The only review below five stars on the maker’s page is a cosmetic one: the fine identifying text on the blade’s reverse is not shown in the product photos.

Full research notes and sources
In the hand
The octagon Pakkawood handle works for left- and right-handed users and, owners note, suits larger hands. They describe the knife as light and balanced through extended peeling work, and as arriving very sharp with an edge that is easy to maintain. These are owner opinions from a small pool on the maker’s page, not independent measurements.
Edge care
The 9.5-12° edge is unusually acute, and that sharpness comes with fragility: the thin blade is more prone to damage under misuse than a Western parer. The maker says hand wash only, and the product page gives no sharpening guidance beyond the edge angle itself. A whetstone matched to the acute bevel is the home route; Zwilling also sells a mail-in sharpening service on its US site. If the edge is badly damaged, replacement is the practical path — there are no user-serviceable parts.
Warranty and repairs
Miyabi is a Zwilling Group brand, and Zwilling’s US limited warranty covers defects in material and workmanship for as long as the original purchaser owns the knife, provided it was bought in the US from Zwilling or a US-authorized seller. It is a replacement warranty, not a repair one: the maker directs repairs to an independent professional, and repair damage voids the warranty. Normal wear and tear, misuse or abuse and alteration are excluded, and claims from unauthorized sellers may be rejected. Zwilling itself has been owned by Werhahn KG since 1970.
Is it worth it?
Miyabi’s own site listed the knife at $104.99 in August 2025 and $99.99 in March 2025 — about $100-105 direct. The rest of Miyabi’s 3.5-inch parers list higher: the Evolution at $109.99, the Kaizen at $129.99, the Artisan at $154.99, the Birchwood SG2 at $204.99 and the Black 5000MCD67 at $244.99, all on the maker’s US paring-knife listing. Value is strongest for a buyer who wants a thin, very acute Japanese parer from an established maker backed by a lifetime replacement warranty. The tradeoffs are the delicate edge, hand-wash-only care and the lack of any independent test or readable owner-forum evidence for the durability claims; no firm buy-below price can be defended from this evidence.
Which model this is
This page covers item 33950-093, the 9 cm / 3.50-inch Koh parer with the brown octagon Pakkawood handle. The maker’s site has sold it under two page titles — “MIYABI Koh 3.5-inch, Paring Knife” and “MIYABI KOH 4000FC 3.5-inch, Paring Knife” — which are the same item. A Kohl’s listing repeats Germany-made, SIGMAFORGE, 57 HRC, three-rivet polymer-handle boilerplate that contradicts the maker’s own specs — treat it as retailer template text, and remember the warranty only covers knives bought from US-authorized sellers.
The Amazon listing for this knife is ASIN B07DCYQ4LT.
