Danish design emerged as a style in the
middle of the 20th century, strongly
influenced by the ideas of the German
Bauhaus. This design movement developed
its own no-nonsense look characterized by
simple formalism, minimalism, clarity and
functionality, as well as by the use of
cutting edge industrial technology in the
realization of this design vocabulary. This is
the tradition of Danish designer and custom
knifemaker Jens Ansø, who designed the
kitchen knife series Boker Pure following
these exact design principles.
The knives have unique, classically simple
lines and offer excellent balance, handle
ergonomics and functionality. This
minimalistic design is highlighted with the
use of "Bergische Eiche," a regional oak
wood, for the handles. The pleasing pattern
of the elaborately finished oak wood is only
interrupted by three understated stainless
steel rivets, which are applied with great
care in a completely manual process.
In order to match the aesthetic quality of
the series with its technical properties, we
use the powder metallurgical steel CPM-154,
made by the American manufacturer Crucible
Industries. This steel is made by melting the
already excellent base steel 154-CM in order
to add more carbides.

The steel is then atomized in a vacuum and
quenched with a cold air jet. The resulting
steel powder is pressed and sintered below
melting temperature. This process makes
it possible to give the steel a much higher
carbide concentration than regular blade
steel; and the carbides give the steel
additional hardness and edge retention.
The bar graph (left) shows the edge retention
compared to an established, popular kitchen
knife steel, the chromium-molybdenumvanadium
steel X50CrMoV15, as well as
to the excellent 440C. The superior edge
retention of the 440C is far surpassed by the
powder metallurgical steel CPM-154, which
is a guarantee for a sharp knife that keeps
its edge for a very long time.
The Pure Series has truly set new limits and
is, with its puristic and functional design
concept and high end materials, the new eye
catcher in your kitchen.
