All-purpose. Blade length 17.7cm, 158g. The spine is approximately 2.0mm thick near the heel. This is a model from ZWILLING J.A. HENCKELS's "Rostfrei" line. It is double-edged and made of stainless steel. A distinctive feature is the anti-sticking protrusion. Both the blade and the handle show little signs of wear and are clean. It appears to be usable for a considerable time. It has been thoroughly sharpened, honed, and polished. Please see my profile for details on the refurbishment process.
