Kast, a young brand based in Cleveland, Ohio, designs and manufactures cabinet and drawer knobs from concrete. Because of their choice of material, their handmade creations are industrial and minimalist in aesthetic. The pieces are also sturdy, composed of up to 10% recycled materials, and sealed with a non-toxic, environmentally-friendly finish. Cast in a variety of traditional shapes, the knobs balance old and new outlooks on design.
