One knife does eighty per cent of the work; this is that knife · review
A German-made 20 cm knife with Zwilling’s FRIODUR ice-hardening, a deep bolster and a seamless handle join — the construction that keeps water out of the handle.
The bottom line The seamless handle and the German origin are the real arguments. Check the bolster reaches short of the edge before committing to sharpening it for twenty years.
A 20 cm German-made chef’s knife in Zwilling’s FRIODUR ice-hardened steel, with a deep bolster and a seamless, non-slip handle.
Seamless. It sounds cosmetic and it is the single most practical detail on the knife: no gap to trap water, no seam to fail, nothing to work loose over a decade of washing.
Deep, which gives balance and a finger guard. Worth checking whether it runs all the way to the cutting edge — a full bolster blocks the stone at the heel, and over years of sharpening the heel stands proud.
A hardness figure. Zwilling describes the process rather than publishing HRC, so edge retention is described rather than quantified.

A cryogenic step in the heat treatment. Zwilling states their FRIODUR process gives long-lasting sharpness and corrosion resistance. It is a maker’s process description rather than a measured figure.
A gap between handle scale and tang collects water and food, and that is where knives fail and where hygiene complaints come from — long before any steel gives up.
