Regarding the appearance of the K860, it continues the elliptical design featured in previous models. Contrasting with the K42, the K860's handle is sculpted and broader at the front, providing added protection for knuckles against steam. Notably, the K860 incorporates automatic shut-off mechanisms, replacing the earlier buzzers and whistles. Plastic played a significant role in the evolution of the electric kettle, initially appearing in the handle for heat insulation and styling purposes (as seen in the K42 Kettle). Subsequently, plastic was also employed for the kettle's spout and handle in the case of the K860.

In manufacturing, the ovular shape discourages imitations from its competitors, primarily because it demands more complex tooling for bending the compound curves. To achieve the distinctive dome shape in the kettle's production, a robust hydraulic press is employed, drawing the dome from a flat, circular sheet of brass (Gotlieb, Rachel., & Golden, Cora, 2004). Additionally, the adoption of an inexpensive one-piece plastic handle and spout eliminates the costly step of soldering the spout, contributing to both efficiency and cost-effectiveness. 

The manufacturing process involves a combination of melting and shaping to craft the desired form. Furthermore, welding and soldering techniques are skillfully applied to join metal components seamlessly. As a finishing touch, steel screws are strategically employed to securely fasten the plastic handle to the kettle's body, ensuring durability and structural integrity.
