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-molybdenum-vanadium
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.
