Needham Knives are made to be used. With a little basic care, your knife should last for years and continue to look better with age.
Most Needham Knives are made from 1084 high-carbon steel. It takes an excellent edge and is a great knife steel, but unlike stainless steel, it requires a little attention to prevent rust.
Cleaning Your Knife
After use, wash the blade by hand with warm water and mild dish soap. Wipe away any food, dirt, blood, or other residue.
Dry the knife completely immediately after washing. This is the most important part of caring for carbon steel.
Never put your knife in the dishwasher. The heat, moisture, and detergents can damage the blade, handle materials, adhesives, and finish.
Preventing Rust
1084 is a carbon steel and can rust if moisture is left on the blade.
After cleaning and drying, apply a very light coat of knife oil or food-safe mineral oil to the steel. You don't need much. A few drops wiped across the blade is enough.
If you use your knife regularly, especially around food, water, or outdoors, oil it more often. If you're storing it for an extended period, clean, dry, and oil it before putting it away.
Patina Is Normal
Over time, carbon steel naturally develops a patina. You may notice the blade becoming darker, gray, or slightly uneven in color.
This is normal and does not mean the knife is damaged. Patina is a natural reaction between carbon steel and its environment and will give your knife more character as you use it.
Patina and rust are not the same thing. Patina is generally gray, blue, or dark in appearance. Active rust is typically orange or reddish-brown and should be removed when you notice it.
Caring for the Handle
Many Needham Knives use natural materials such as hardwood or antler. These materials can change slightly in appearance over time with use.
Avoid soaking the handle in water or leaving the knife submerged. Wash the blade carefully, wipe the handle clean when necessary, and dry everything thoroughly.
An occasional light coat of food-safe mineral oil or appropriate wood conditioner can help maintain unfinished or oil-finished wooden handles.
Caring for the Sheath
If your knife comes with a sheath, make sure both the knife and sheath are completely dry before storing them.
For long-term storage, it's generally better to store a carbon-steel knife outside a leather sheath. Leather can hold moisture against the blade and contribute to corrosion.
Kydex-style sheaths can also trap moisture or debris, so keep the inside clean and dry.
Keeping Your Knife Sharp
A sharp knife is safer and performs better than a dull one.
For normal maintenance, a ceramic honing rod or leather strop can help keep the edge sharp between full sharpenings. When the knife eventually needs sharpening, use a quality sharpening stone or guided sharpening system.
Avoid aggressive powered sharpeners unless you know how to control the heat and angle. Excessive heat at the cutting edge can damage the steel's heat treatment.
What to Avoid
Do not put your knife in the dishwasher.
Do not leave it wet or submerged in water.
Do not store a wet knife in its sheath.
Do not use it as a pry bar, screwdriver, or chisel.
Do not chop or strike materials the knife wasn't designed for.
Do not leave carbon steel exposed to moisture for extended periods.
Built to Be Used
Your Needham Knife doesn't need to stay perfectly polished to be taken care of. Scratches, patina, and signs of use are expected.
Clean it, keep it dry, give the steel a little oil, keep the edge sharp, and use it.
