The K2 is an indispensable, wide petty knife. 

The Windmühlenmesser K series knives are inspired by classic Japanese double bevel designs. They have impressively thin geometry and are easy to sharpen, making them a shop favorite. The blades feature a "blue" glaze, a shiny final polish achieved by using a synthetic stone powder. The ergonomic handles are hand polished and shaped in house.

These are made with a European carbon steel with at least 1% carbon steel with the addition of vanadium. It is similar to Japanese aogami 2 steel (but with vanadium), which gives it excellent edge life and toughness. Toughness aside, they are ground thin for smooth cutting and will not tolerate misuse.



About This Knife

Carbon Steel

Reactive blade.

Utility

A utility knife is a mid-sized kitchen knife built for tasks that are too small for a chef’s knife but too large for a paring knife. Its narrow, agile blade handles jobs like slicing citrus, trimming proteins, cutting sandwiches, and prepping smaller vegetables. The pointed tip provides precision, while the added length offers reach and stability. It’s a versatile everyday tool that fills the gap between the two core knives in a kitchen.

  • This is a reactive carbon steel knife.

  • Expect oxidation (color change, staining, spotting) with use.
  • Prolonged exposure to moisture or food debris will cause rust; remove any rust with a light abrasive.
  • Use only on a quality wooden cutting board.
  • Do not use on hard surfaces like bamboo or plates.
  • Don't twist or scrape the edge on the cutting surface to avoid early dulling and edge damage.

Medium-fine finish

We recommend sharpening by hand using whetstones starting around 1000 grit progressing to at least 4000 for this steel type and edge geometry. Finish with a monodiachrome strop for a smooth cut with a substantial bite. Finer finishes are possible, but the knife may slide on smooth foods and overall edge retention may suffer. During repair, use a super coarse stone to pass chips quickly to help keep flat bevels.

  • Avoid pull-through sharpeners and non-water-cooled mechanized systems.
  • Strops and ceramic honing rods are preferred for as-needed edge maintenance. If you have to use a honing rod to be able to use the knife comfortably, it's time to sharpen the knife.

About Windmühlenmesser - Robert Herder

Solingen, Germany

Robert Herder, also known as Windmühlenmesser (“Windmill Knives”), has crafted knives in Solingen since 1872. Renowned for thin grinds and razor-sharp edges, Windmühlenmesser uses traditional Solinger Dünnschliff (thin grind) techniques and hand-finishing on many models. Their carbon steel paring knives and classic vegetable knives are especially beloved. With wooden handles, patina-prone steel, and a lightweight feel, Windmühlenmesser knives evoke another era—yet still outperform modern mass-produced alternatives. These are tools made to be sharpened and used for life, combining elegance and enduring German craft.
