Buying
As
you will guess from our "Premium" name (PremiumHG.com) we are pretty
serious about the quality of our products and as a result only carry the finest
kitchen cutlery available. Our hope is that the following will help you
select a set of knives for you to enjoy and use. With so many kitchen
knives available, it can be hard to choose which knife is best for you.
Don't worry - we are here to help. Let's break the kitchen knife down to
its components of purpose, blade styles, materials & design, determine how
many knives you will need, and, finally, dispel some myths.
Purpose
The knife's purpose does not define how the knife looks, but rather what the
knife is used for - such as chopping vegetables, boning chicken or fish,
slicing, or cleaving through a stack of ribs. Different countries shape knife
differently regardless of purpose.
Blade Style
The blade style defines the look, shape, thickness, handle, and type of grind
needed for a specific purpose. For example a traditional Chinese vegetable
chopping knife is the Chinese Cleaver. In Japan, the same knife is either
the Santuko or Usuba knife, while in Europe and the US, we think of the standard
chef's knife. The look, shape, thickness, handles, and type of edge grind
have all evolved based on the cutting task and the ergonomics needed to
accomplish the purpose and cutting requirements. Blade style also encompasses
other features such as the Mac Knife's safety rounded tip, which reduces
accidents in the tight and cramped confines of restaurant kitchens.
Blade
style is important in determining the right tool for the right job. As a chef,
you may prefer to have several knives that accomplish the same purpose, but have
different blade styles for different types of cooking. If you tend to do
more Asian style cooking, preparation for those meals and their related cutting
tasks can be easier with Asian style knives. Making sushi is a good
example of this concept. Although a standard slicing knife can do the job,
the Yanagi Sashimi knife has evolved over hundreds of years, specifically for
this delicate task and will provide all levels from the novice to the expert
much better results than any other style of knife.
Materials & Design
Materials are really where professional knives separate themselves
from lower quality knives. The better the grade and type of steel the
better the knife. The higher quality steel ultimately holds an edge and
cuts better and longer than a comparable style knife with a lesser grade and
type of steel.
Knife steels have advanced quite a bit in the
last decade. In fact, a steel called VG-10, a cobalt based steel, was
designed specifically for the cutlery industry. The pinnacle of knife
steels are used in Damascus knives such as the Shun knife brand which have the
VG-10 steel cutting edge core forged inside beautiful multi-layered stainless
steel that adds strength - thin and strong. The most common type of
premium steel is Chromium-Vanadium (Chromova or CrV) which you will find in
Global, Messermeister, and Bunmei. Mac Knives uses a more advanced
Chromium-Vanadium alloy with Tungsten steel and additional carbon to increase
the sharpness and edge holding of their knives. Although, Chromium-Vanadium
grades of steel will vary, even in its less optimal forms, it is still superior
to many steels used in cutlery. Swiss Inox steel is another steel which is
a good but less expensive cutlery steel used in the Forschner line. Inox steel
will not hold an edge quite as well as the other premium steels, but it
re-sharpens very easily, and has a very high stain and rust resistance.
Design
focuses on combining the purpose, blade style, and materials with aesthetics.
Handle materials and the aesthetic design of the knife range from visual appeal
to durability to price. After the purpose and style of knife has been
chosen, then decide on the various design options that fit your needs.
How many knives should I have?
This really depends on you and your cooking style, however most people will need
at the very least a paring knife, a 5"-6" utility knife, and a
7"-10" chef/chopping knife. If you slice a lot of bread, bone
meats, make sushi, ...then adding a dedicated knife for each purpose will make
each task more enjoyable and a little easier. Some of our customers are
completely content with a good chef knife and a long utility paring knife,
others prefer a more standard set of knives that includes chef, paring, boning,
bread, utility, slicing, and serrated tomato/sandwich knife.
Dispelling Some Myths
Contrary to popular opinion, a dishwasher is
no place for your kitchen knives. The two primary reasons are: abrasives and
heat. Abrasives will dull the fine edge of your knife within one or two
washings. The heat can crack the knife handle and will re-temper the knives over
time to the point where they will no longer hold an edge with any amount of
sharpening and will need to be replaced.
Many people have been mis-informed that German knives are always the
best. We see a lot of knife brands from a variety of countries and
that statement would be a very bold statement regarding any country. In
reality we have seen some truly great German knives such as the Messermeister
line of cutlery, which features all the best that German knives have to offer.
Conversely, we have also seen some other popular German knife brands which, in
our opinion, have either let their quality slip and just don't measure up to our
standards of fit, finish, and quality. Japan to many is also though to have the
best cutlery, however the same logic applies - the Shun knives are spectacular,
however that $20 30 piece knife set your can cut
a tin can in half with are not.
We
are asked frequently where to find a Solingen Brand knife. Solingen
is a town in Germany which was the epicenter of steel manufacturing in Germany
much as Seki City in Japan is today. Today manufacturers located in
Solingen Germany typically make blades for other companies, you will see the
word Solingen stamped on the tang of the knife, if it was made there.
Surgical
grade steel is a broad term which really means very little other than that
the steel is unlikely to form rust quickly. When a knife is advertised as
Surgical Steel or Rostifre' (Rust-Free), it usually indicates a lower grade
steel and knife. As an example, your everyday flatware is surgical grade
steel, however it is very unlikely that they would either produce a good edge or
maintain it for very long. As a result, all premium grade steels are
surgical grade, however most steels are not premium grade. Like comparing
a Yugo to a Ferrari, premium steels do cost more to manufacture and finish. The
end result is a knife that is more expensive but will deliver much better
performance.
Ice Hardened is another relatively meaningless term that is mentioned
quite a bit in marketing and advertising. In truth all quality knives are
heated and cooled in various combinations to strike a balance between durability
(flex) and hardness (edge holding).
Cutting
boards don't matter. With the exception of those pretty cuts a sharp
knife will leave on your kitchen counter, it is a very bad idea from a knife's
perspective to cut on anything other than a wooden cutting board or a soft
plastic cutting board. A hard cutting surface does two things -
artificially dulls the cutting edge on your knife faster than it normally would
and a hard surface also can prevent a knife from completing its cut. To do
its job, a knife must pass through the food and slightly into the cutting
surface. Clean fast chopping is almost impossible on a hard cutting
surface. If you haven't noticed, there is a reason all those wonderful fast
chopping celebrity chefs on TV always use a wooden cutting board (usually John
Boos). As a general rule, if you can't make an indentation or mark with
your finger or thumbnail into the cutting surface, it is too hard to cut on with
fine kitchen cutlery.
"But
I just cut it on my granite countertop." Stop this now please!
Yes that granite is really tough stuff, but that delicate knife edge is not. You
might as well take your new knives out any try cutting through a rock. There is
a reason they use diamond cutting wheels to cut granite, it is so hard it will
dull a kitchen knife in only a few passes.
Sharpening
a knife is hard. Not really. In most cases it takes about as
much skill as using a knife. A multitude of gadgets fill the market to
sharpen a knife, however we have found that there are couple simple ones that
consistently produce excellent results. First you need to determine which kind
of person you are. Do you use a steel or ceramic steel (the long round
pointy thing in you knife block) each or every other time you use your knives,
or are do you wait until the knives are completely dull and need an overhaul.

- Sharpening a little each day is the best way to
maintain the edge of a knife. We have found that the inexpensive Mac
Ceramic Sharpening Rod takes off just enough steel that it will maintain the
edge of a knife if used at least once a week and it comes with instructions.
The simple-to-use cutting motion Mac RollSharp or MinoSharp sharpeners does a
great job of re-establishing the edge bi-yearly. Another super easy-easy-to-use
knife sharpener is the Spyderco Sharpmaker which even comes with a video and
sharpens serrated knives as well and pretty much anything with an edge in your
house..

The
greatness and quality of those infamous knives as-seen-on-TV and sold door to
door remains a great topic of debate. Without a doubt, everyone should
have at least one of these serrated hand-held chain saws to cut those things you
would not think of using that brand new $80 knife on, such as: frozen food, wire or
plastic turkey ties, hobby/household cutting chores, light pruning, shoe
leather, or even the occasional aluminum can. To our knowledge, we don's
make any food so tough that it requires that level of attack.
Additionally, some of these knives are not
inexpensive. Cooking is an enjoyable, life-long hobby that can be very fun with
the right tools. We recommend putting some thought into your long-term
knife purchase prior to buying that knife set on TV or from your friends younger
second cousin. Although a good quality set of knives may be
ill-designed for the destruction that can be wrought with a cheap serrated
knife, they are perfectly designed for helping you prepare a lifetime of
wonderful meals.
