Robert Herder – Windmühlenmesser “K3” Fillet / Compact Chef
––––––––––––––––––––––––––––––––––––––––––––––
K3 – Flexible Precision
The K3 sits between a small chef’s knife and a fillet knife. Compact at 124mm, lightly flexible and extremely thin behind the edge, it’s designed for detailed prep and smaller filleting jobs.
It’s particularly well suited to:
– Board work
– Filleting fish
– Trimming meat
– Chopping smaller ingredients
– Fruit and vegetable prep
Light (56g) and agile, it rewards a controlled hand rather than heavy pressure.

K Series – Thin by Design
The K Series takes inspiration from Japanese double bevel geometry, prioritising cutting performance through thinness.
Each blade is shaped using Windmühlenmesser’s traditional dry-fine grinding technique. This produces a razor-sharp edge and an extremely thin cross-section, with a subtle concavity along the blade face to aid food release.
The effect is noticeable on the board — less resistance, cleaner cuts, and a lighter overall feel than most Western knives.

Robert Herder – Solingen Since 1872
Founded in 1872 in Solingen, Germany, Robert Herder remains family run and committed to traditional grinding methods.
Their knives are refreshingly thin and lightweight by Western standards — less overbuilt, more geometry-led. Performance comes from grind and heat treatment rather than mass.

Steel Options – Stainless or Carbon
Available in stainless steel or classic carbon steel.
The carbon version (approx. 60 HRC) takes a very keen edge and sharpens beautifully on stones. The stainless option offers simpler day-to-day maintenance while retaining excellent cutting performance.
Both are ground extremely thin behind the edge (approx. 0.26mm), contributing to their precise feel.

Handle – Plumwood
Finished with a plumwood handle — warm, comfortable and well balanced against the blade’s light weight.

A Note on Carbon Steel
We favour carbon steel for its ability to take a finer edge and hold it well — but it does require care.
Wash and dry thoroughly after use. If light surface rust appears, a gentle rub with a dry scourer will usually remove it. Over time, a patina will develop — natural, protective and entirely part of the knife’s character.
And for many reasons — never put your knives in the dishwasher.
