What is the difference between 18/10 and 18/0?
In order to be called stainless steel, a steel alloy must contain at least 11.5% chromium.
Aside from the knife blades, which contain more carbon and less chromium to ensure blades
are sharp and stay that way, all of our flatware is made using 18% chromium. Some of our
flatware, labeled as 18/10, contains nickel in addition to the chromium, which adds to the
steel's resistance to corrosion as well as its luster. Because of a recent world shortage of
nickel, which consequently doubled its price, we have consulted with independent
metallurgists to assess the alternatives to using nickel. We learned that 18/10 stainless
steel has a resistance to corrosion that far exceeds what is required for normal domestic
use. Our 18 chrome stainless steel, properly processed, still meets our high standards for
quality and passes all standard corrosion tests.
How do I Care for my Knork Products?
Product Care and
With proper care, our KNORK sets are designed to last for many years. Stainless steel is a
hearty material that resists rust much better than other flatware mediums due to the
presence of chromium, leading it to become the predominant manufacturing material used in
flatware production. Its name means that it "stains less”, but stainless steel is not a 100%
infallible material. Stainless steel does not readily corrode, rust or stain with water as
ordinary steel does. However, it is not fully stain-proof in low-oxygen, high-salinity, or
poor air-circulation environments.
As far as care, we do recommend using a non-citrus scented liquid detergent if
possible, and avoiding compacted tablets (an example of these is the “Finish” brand
tablets with the red “power” balls in the middle-these tend to be harsher and can damage
the top coat of the stainless steel, which would cause rusting or spotting to
Avoiding soaking pieces for any extended period of time is also important: stainless steel
hates damp and dark environments, so a wet sink is a perfect place for rust/corrosion to
thrive. Rinse pieces of any acidic residue or food (mayo, ketchup, butter, mustard, sour
cream, etc.) until you can fully wash and put away, and make sure pieces are clean and dry
before going in your drawer, making sure there is no pooled water anywhere on the surface.
Using a high heat drying cycle in your machine will ensure that pieces are not sitting with
water spots on them in a rust-friendly environment after a completed wash cycle.
Titanium PVD Colored Flatware
While our titanium PVD coated colored line is certainly dishwasher safe, handwashing is
recommended as it is the gentlest care method. If dishwashing, it is recommended to separate
different items into different washing compartments to prevent scratching that blades and
sharp edges could potentially cause. Use a mild, non-citrus dish soap for hand washing, and
if machine washing, a non-citrus mild liquid detergent is recommended. Powders or compacted
tablets can be hard to dissolve and the granules can be abrasive and damaging.
Avoid using any abrasive sponges or scrubbers (including Scotch-Brite or steel wool), as
these can irritate and damage the PVD finish.
