Henning Kjærnulf was a Danish designer and architect active during the mid-20th century, whose work evolved from the clean, functional lines of classic Scandinavian modernism to a far bolder, more sculptural expression. His earlier designs reflected the understated elegance typical of Danish craftsmanship, but it was his later pieces, most notably the Razorblade armchairs and dining chairs, along with a series of richly carved oak sideboards and cabinets for Nyrup Møbelfabrik that truly set him apart. These works pushed the boundaries of Scandinavian design, blending traditional woodworking with dramatic ornamentation and architectural detail, resulting in furniture that feels both timeless and daringly expressive.

Currently there is limited authenticated biograplhical information on Henning Kjaernulf, which makes him somewhat an enigma of the Danish mid-century design scene. There are however a number of documented designs that highlight his ability as a furniture designer and architect. Kjaernulf has produced designs for the following Danish furniture makers; Boltinge Stolefabrik, Bruno Hansen Møbelfabrik, EG Kvalitetsmobel, Korup Stolefabrik, Nyrup Møbelfabrik, Ølholm Møbelfabrik, Sorø Stolefabrik, and Vejle Stole og Møbelfabrik.
