C40 Nitro Blade
Built for true coee enthusiasts and specialty coee con-
noisseurs, the C40 (MKIII) Nitro Blade is a robust high
performance coee hand grinder with an advanced burr
set design. The selection of the burr material is the proud
result of dedicated research and development. Earlier in
2015, we decided to chose a very special high-alloyed,
high-nitrogen stainless steel with a ne martensitic matrix
as our top of the line burr material.
We further rened the geometry and structure of the
Nitro Blade burr to get the grind performance we were
looking for and the particle distribution which worked
best with brewing fresh ground specialty arabica beans.
Manufacturing a Nitro Blade is a serious engineering
task which requires special tools and machinery, excel-
lent craftsmanship and lots of experience. High-nitrogen
martensitic steel is extremely dicult to work with. But
when nished, it is tough, highly wear resistant and has a
high degree of edge retention. This is what we want.
After hardening and tempering a nished Nitro Blade, we
give it the last engineering kick. We cut tiny micro-blades
on the tips of the Z-teeth to give it an ultra sharp burr
entry. The grind result gives you a very rened particle
size distribution for all grind grades from coarse grind
for hand brewing to ne grind for pulling espresso shots.
We love our little masterpiece. It shows our heritage from
Bavaria and Black Forest in Germany.

We think stainless steel is the right choice to build a
robust coee grinder. So the C40 has a stainless steel
body, a stainless steel axle, a stainless steel crank and
stainless steel micro ball bearings.
The “naked” C40 has a brushed stainless steel body. For
the wood version, we laminate a genuine wood layer on
top of the stainless steel body. Both body surfaces give
you a solid grip for serious crank action.
Grind thruput
Comandante burr sets are always cut from solid metal
blocks by experienced craftsmen. Burr geometry has
been optimized to achieve excellent grind thruput with
medium crank torque delivering rened grind particle
size distribution for best brew results. Grind thruput aver-
ages at 1 coee bean per turn at a comfortable medium
turning force.
Nitro Blade Burr Set
The Nitro Blade burr set is the ultimate performance
choice. It “cuts” coee beans in a very unique way. The
grind result is extremely exact and very uniform with the
least amount of coee dust. Both ring and core are cut
out of a solid block of high-alloyed, high-nitrogen stain-
less steel. This makes the Nitro Blade very sharp and
strong with excellent edge retention and wear resistance.
Nitro Blade is also extra non-corrosive and shows an ex-
cellent cut performance.
JPlease be careful! J
Danger: Sharp Burr Edges and Burr Teeth!
Please be extra careful when your ngers get close to any
burr edge or burr teeth. Both burr edge and teeth are very
sharp and can easily cut and seriously harm you.
Please keep your children away from the burr!
Highly Inert Burr Surface
The Nitro Blade‘s steel surface is highly inert and there-
fore performs with absolute sensoric neutrality. This is
particularly essential when grinding complex acidic high
quality micro lot arabica coee. The Nitro Blade with its
physical and chemical properties is the top choice for all
serious coee brewers and top baristas.
Try your Nitro Blade also with salt and pepper or other dry
herbs. You will be surprised about the grind result. Fresh
ground seasoned salt powder – extremely tasty!
Coffee & Tea
Nitro Blade is an excellent grinder for both coee and tea.
Yes tea! The special burr geometry in combination with
the highly inert stainless steel blades give you a tool to
discover new avor dimensions.
Axle with Micro Ball Bearings
The center axle is xed and supported by two micro ball
bearings for better distribution of force and grind mo-
mentum. Both micro ball bearings are encapsulated with
rubber for protection and smooth operation.
The turning crank is made of stainless steel and can be
removed to better ll the C40. The clear disc on the crank
has been pressed onto the stainless steel quite solidly,
but can be adjusted if necessary.
100% Natural Oak Wood
The wooden knob is made by a friend in the Black Forest
region. It is made of 100% natural oak wood and is
mounted with a push-button-mechanism onto the crank.
You are able to remove it and click it back on. Shape and
form of the wooden knob have been designed for com-
fortable and solid feel during grinding.
All wooden surfaces have been treated with a safe Wax-Oil.
Safe TRITAN™(BPA-free)
All burr frame parts in synthetic material are made with
BPA-free copolyester TRITAN™ which is known to be a very
robust and break-resistant synthetic material. According
to Eastman, TRITAN™ is not only BPA-free, but it is also
not manufactured with bisphenol-S or any other bisphe-
nol compounds. In addition, third-party labs have tested
TRITAN™ and the results have demonstrated that it is free
of estrogenic and androgenic activity. A very safe material
to hold your precious coee beans.
Grind Grade Selection - 3-Way Click Action
The grind grade selection dial has been designed like a
three-legged star with a proper click action. We use three
independent micro steel ball click units to assure a bal-
anced pressure scenario for the burr conus. It is located
at the bottom of the C40. Use three ngertips and turn
the star clock-wise to get a ner grind result or counter-
clock-wise for a more coarse grind. The click action rmly
locks in your preferred grind grade.
But please be careful with your ngers when you operate
close to the burr edges. The Burr edges of Nitro Blade are
extra sharp. You can easily cut and harm yourself if you are
not careful.
Glass Jar with Lid
The glass jar at the bottom holds 40 grams of coee which
gives you approximately 4–5 cups of coee. We use glass
because it is a perfect storage device and you can easily
clean it with hot water. You get 2 glass jars with the C40.
One in clear and one in brown. Plus, you get a lid for your
extra glass jar. The lid is made of Urochem 371, which is
manufactured from renewable natural resources and can
be recycled.
Please be careful!
• Please be extra careful when you use this coee
grinder. The attached glass container may break
when it hits a hard surface like the oor. Broken glass
is dangerous and can seriously harm you!
• Please don‘t let children play with this coee grinder. It
is heavy, it has very sharp blades and a glass jar which
can break!
