details of our outdoor knife blades
At
the end of the 19th century the Sheffield cutlery industry
employed around fifteen thousand people and as the 20th
century came to life the constant quest for improvement
in the manufacture of cutlery increased pace. In the 1920's
an exciting new development was made public by a local Sheffield
metallurgist - STAINLESS STEEL. It became the industry standard
for cutlery. Having now had time to further develop stainless
steel from this fresh beginning we begin the 21st century
with exceptionally advanced materials from which our cutlers
can produce truly fine blades.
Our outdoor knives are produced from a range of stainless
steels called Martensitic stainless steels. The steel has
been specially formulated for cutlery and in particular
knife blades and gives an extremely keen edge due to the
hardness.
For those of you interested in the technical specification
of the stainless steel used for the blade, below are a few
details for your interest. For those of you not so technically
minded you may enjoy the History
of Blade Making instead.
Grade of Stainless Steel
Martensitic Stainless Steel European Designation : 1.4034
Characteristics
The characteristic feature of this Martensitic Stainless
Steel is its ability to be hardened by quenching and tempering.
This steel has excellent fatigue behaviour combined with
good corrosion resistance.
Corrosion Resistance
Due to the chromium content of 14% (mean) this Martensitic
Stainless Steel can be used in contact with foodstuffs.
The good corrosion resistance is due to a careful balance
of the alloying elements used to obtain high strength after
quenching. This grade is particularly suitable for applications
requiring resistance to corrosion in the following media
:-
1)
Fresh waters and streams.
2) Oils
3) Picric and lactic acids
4) Chloride free neutral and alkaline salt solutions.
Hardness after oil quenching (typical values 1mm thick)

The history of blade making in Sheffield, England
The history of blade making in Sheffield, England is so deep as to require
volumes to tell and to detail the full history of blade manufacture in
Sheffield would take a web site of mammoth proportions, such is the depth
of our history. We Sheffielders are proud of this history and that the
skills learnt over the centuries have not only been retained by today's
cutlers but that we are adding our own page to the wonderfully rich tradition
for which our city is justifiably famous.
Tower of London
Sheffield has been the home of cutlery for almost the last thousand years.
Way back in 1340 when King Edward III (1312-1377 AD) was King over England,
Ireland and France, an inventory of his possessions in the Tower of London
made note of a Sheffield Knife. In fact he so valued this knife that it
was recorded in his will. You can be sure that the beneficiary must have
been equally as proud as the King to own such a treasured item.
Later on in the 1380's Chaucer wrote about a Sheffield knife in the Reeves
Tale. Interestingly portraits have been painted of Chaucer wearing such
a knife.
An abundance of natural resources in Sheffield gave rise to the cutlery
industry. The beautiful surrounding hills produce six rivers which flow
through the city and were used to power the water wheels. Good quality
iron ore and coal to smelt and forge are found locally together with sandstone
for the polishing and grinding wheels. Our ancestors used these natural
gifts and developed their talents over many generations to earn the respect
of the world with the quality of their knives.
Throughout history these knives have given pleasure to King and commoner
alike, thanks to today's modern technology we can now show our wares to
a wider audience.
Made in Sheffield for people who recognise quality.
