Caring for your Morakniv®
Types of Steel and Alloys
Currently, we produce knives with blades made from various types of steel:
1. Carbon steel, known as C100 steel, alloyed with 1% carbon. Typically 58-60 HRC.
2. Sheet steel according to AISI 01 with approximately 1% carbon content in the core. 58-60 HRC
3. Stainless steel, 12C27. Typically 56-58 HRC
Daily Care
All blades that are not stainless steel will oxidize (rust) and are affected by humid and corrosive environments. Therefore, we recommend drying and lubricating the blade after use. Clean and dry the blade carefully to avoid injuries. Some knife owners even apply a patina to make the blade more resistant to rusting. Patina can easily be created by inserting the knife into some fruit for a few hours or simply rubbing the blade with hot vinegar. Good tips and recommendations can be found on knife forums online, especially on YouTube.
However, applying a patina is always at the owner’s initiative and risk.
Carbon and sheet steel knives should never be washed in a dishwasher. The aggressive dishwasher detergent reacts too actively with the blade.
Blades made of stainless steel do not require special care to prevent rust. Still, get into the habit of always rinsing the blade under hot running water, preferably with a mild detergent, and drying it if the knife is dirty after use. Even if the blade is stainless steel, salt stains and others can remain, which are difficult to remove if not cleaned immediately. Stainless steel knives should not be washed in a dishwasher. The aggressive detergent has a clear adverse effect on the blade, and the sharp knife can damage the dishwasher's interior during operation. There is also a high risk of injury from a sharp knife when loading and unloading the dishwasher. However, the high temperature in the dishwasher does not cause problems. We know, for example, that our knives are used in autopsies, after which they are sterilized in hospital autoclaves at temperatures up to 120°C.
Our Bushcraft Black features a carbon steel blade with a black, scratch-resistant coating that protects against rust almost as well as our stainless steel blades. The thick 3.2 mm blade of the Bushcraft Black is hardened a bit more than 56-58 HRC for better durability in load-bearing on the blade when striking. Therefore, the sharpening angle is slightly larger (~27°) to withstand heavy loads.
The blade is made of boron-containing steel, 52-54 HRC. Boron-containing steel oxidizes like other carbon steels and requires corresponding care, i.e., the recommendations for carbon and sheet steel (see above).
Blade Maintenance
Honing or sharpening dull blades requires knowledge and experience.
Sharpening the blade of the knife with a fine whetstone (only for carbon and sheet steel) or a diamond stone (for all types of knives) is learned quite quickly, although it requires some practice. Always work at the same angle at which the blade was initially sharpened, usually 23°, but this depends on the knife model.
If you want to use a knife sharpening machine, we recommend TORMEK machines or equivalent.
To have a good knife, we recommend Sharpex and GS Schleiftechnik sharpening machines.
It is absolutely crucial to sharpen the knife cold, i.e., using water to cool it, to avoid compromising the blade’s tempering (hardening and tempering). If the blade turns blue or discolors, this is a sign of overheating. Grinding that discoloration away won’t help – it’s just sweeping dirt under the rug.
Never use carbide type sharpeners, where the blade is drawn through a V-shaped form, as these remove too much material.
SOG KNIVES General Section
What to do if oxidation or rust appears on my SOG?
If oxidation or rust appears, clean and rub the affected area with a soft cloth and apply a layer of lubricant over the entire surface of the knife. For affected areas, use a deoxidizer (e.g., Miracle Cloth) after cleaning, then apply a protective product (e.g., Sentry’s Marine Tuf-Cloth) to prevent further oxidation and remove excess particles. You may try to remove the rust with a wool pad of mild steel (000 abrasive particles), then reapply the anti-corrosion agent.
Important! Rust and corrosion most often occur due to irregular maintenance, so the best defense against oxidation or rusting is regular cleaning and lubrication of the knife.
What to do if I’ve disassembled my knife/tool and can’t put it back together?
Disassembling your knife or multi-tool voids its warranty. If this happens, you can send it to us, and we will assemble it for a $20.00 fee.
What does "improper use" or "misuse" of my knife or tool mean?
Unrecommended activities include, but are not limited to: disassembling the knife/tool; using the knife as a screwdriver, pry bar, or chisel; throwing the knife (unless it is meant for throwing); improper storage; failure to follow SOG’s general maintenance instructions.
Fixed Blade Knives
What care should I take for my fixed blade knife?
Keeping your knife clean, dry, lubricated, and sharp are essential defenses against corrosion, wear, and potential injuries. Proper care for your knife prolongs its life and enhances its resource and reliability. Keep your knife clean. Clean the blade and handle after each use, but do not immerse the knife in water, especially if your knife has a leather handle. A mild solution of soap and water removes dirt and particles that accumulate during use (avoid strong detergents like laundry powder, dishwashing detergents, and chlorine-containing products).
Keep your knife dry. After cleaning or getting wet, dry the blade and handle of your knife thoroughly, paying special attention to sensitive handle materials, such as leather. Use a soft cotton cloth or chamois with a small amount of moisture-absorbing oil (WD-40 or 3-in-1) only on the blade to prevent water spots and oxidation.
Keep your knife lubricated. Fingerprints and atmospheric conditions are the main causes of rust or corrosion on the blade of the knife. To keep your knife looking perfect, it is recommended to apply a thin layer of oil to the blade after each cleaning and before placing it in storage for a long time (you may need to lubricate more often if you live in a damp environment or near the sea). If your knife is stored for an extended period, it is recommended to use a dehydrating agent to remove airborne moisture. Please note that even stainless steel will rust if not properly maintained.
Keep your knife sharp. A sharp knife is safer and easier to use than a dull one. If you are a novice in sharpening knives, we recommend investing in a fixed-angle sharpening set for even sharpening from tip to base. We also recommend initially practicing with your kitchen utensils before tackling your SOG knife. SOG provides factory sharpening for a minimal fee of $12.00. We will be glad to assist you in this regard. You can also try SOG’s sharpening tool for edge restoration. (Note that damages to the blade caused by sharpening at home are not covered by the warranty).
What is not recommended for my fixed blade knife?
Fixed blade knives are used for various purposes and under different circumstances. You will find that your knife can become an invaluable tool for you. Uses and applications vary for each knife, but the general rule is not to use the knife for prying.
How should I store my knife?
When not in use, lubricate the blade and store it in a cardboard sheath/holder. Do not store the knife in its original plastic/nylon/leather sheath, as it may retain moisture that accelerates oxidation or rusting. The cardboard sheath absorbs moisture from the blade's surface and prevents dust and dirt accumulation. Store your knife in a controlled temperature environment with low humidity. Periodically lubricate the blade during storage, approximately two or three times a year. Remember that even the best steels rust and oxidize without proper care, so good maintenance of your knife ensures its longevity and reliability over the years.
Folding Blade Knives
What care should I take for my folding blade knife?
Keeping your knife clean, dry, lubricated, and sharp are essential defenses against corrosion, wear, and potential injuries. Proper care for your knife prolongs its life and enhances its resource and reliability.
Keep your knife clean. After each use, clean the blade and handle. A mild solution of soap and water removes dirt and particles that accumulate during use (avoid strong detergents like laundry powder, dishwashing detergents, and chlorine-containing products). It is best not to submerge the knife in water. To clean the interior of the handle, you can use a toothpick or ear cleaning swab for small quantities of dirt and dust. A can of compressed air might be helpful for clearing away debris and lint. (Follow product safety instructions, as some compressed air cans contain a catalyst that can damage the knife's finish).
Keep your knife dry. After cleaning or getting damp, thoroughly dry the blade and handle of the knife, using ear cleaning swabs for hard-to-reach areas. Use a soft cotton cloth or chamois with a small amount of moisture-absorbing oil (WD-40 or 3-in-1) only on the blade to prevent water spots and oxidation.
Keep your knife lubricated. Fingerprints and atmospheric conditions are the main causes of rust or corrosion on the blade of the knife. To keep your knife looking perfect, it is recommended to apply a thin layer of oil to the blade after each cleaning and before placing it in storage for a long time (you may need to lubricate more often if you live in a damp environment or near the sea). For the hinge, use paraffin oil (e.g., Easy Lube, available at Walmart, or Clean Ride, which can be found at most bicycle shops), which not only provides smooth action when opening and closing but also repels dirt and particles that could hinder its performance.
Keep your knife sharp. A sharp knife is safer and easier to use than a dull one. If you are a novice in sharpening knives, we recommend investing in a fixed-angle sharpening set for even sharpening from tip to base. We also recommend initially practicing with your kitchen utensils before tackling your SOG knife.
SOG provides factory sharpening for a minimal fee of $12.00. We will be glad to assist you in this regard. You can also try SOG’s sharpening tool for edge restoration. (Note that damages to the blade caused by sharpening at home are not covered by the warranty).
BUCK KNIVES Usage Instructions
BUCK KNIVES ARE DESIGNED FOR CUTTING
Do not throw, hammer, chip, or chop with a Buck knife. It is not safe and if you damage the knife as described above, it may void the warranty. Strong impacts or bending can also damage your knife, or even worse – cause injury. If your knife has a locking blade, always check if the locking mechanism has engaged before use.
Buck knives have a long life. Cleaning and care for your knife preserve its characteristics and extend its life.
Keep the knife dry. This means the entire knife, not just the blade.
Keep the knife clean, especially the moving parts and locking mechanisms.
Keep the knife lubricated, especially the hinge joints and blade. Lubricate at least twice a year.
Keep the knife sharp – a sharp knife is safer than a dull one.
Do not try to repair a damaged knife yourself. Send it to us, and we will make it like new.
Store your knife in a dry place.
CLEAN YOUR ENTIRE KNIFE REGULARLY
This includes the blade, hinge joints, and locking mechanism. It is best not to immerse the knife in liquids. But if it happens, dry the entire knife well. Aerosol cleaners are a good alternative. Clean and lubricate your knife regularly to prevent dirt accumulation, surface oxidation, and rust appearance. After cleaning, always lubricate the knife. We recommend Wax Lubricant. It lubricates, seals, and protects the knife from surface oxidation and moisture-induced corrosion.
RECOMMENDED CLEANING AGENTS
Clean Streak leaves no residues. It is an excellent agent for cleaning metal surfaces and is easy to use. Simply spray and wipe. No rinsing or submerging of the knife in liquids is required.
Metal Brite is a polishing agent. It removes surface oxidation, rust, tarnish, and adhered dirt while providing a protective coating.
For blade cleaning, you can also use chemical solutions like acetone, nail polish remover, MEK, alcohol, and paint thinner. Keep in mind that these solvents can damage some Buck knife handles.
Do not use strong cleaning agents containing chlorine, such as laundry powder. They accelerate metal corrosion.
DISCOLORATION IS A SIGN OF OXIDATION
If you notice that the metal has a bluish, gray, or black color, this is a sign of oxidation and a precursor to rust.
The stainless steel used by Buck does not discolor easily. If you notice a change in the metal's color, clean it immediately. It is a sign of impending rust.
Discoloration is typical for non-stainless steels. But regular cleaning will prevent the metal from rusting.
Getting Rid of Rust
Rust is reddish-brown. It corrodes the blade and contaminates what you cut. Light rust can be cleaned and removed with lubricating oil. Deep rust requires applying abrasives.
We recommend Metal Brite – an excellent polishing agent for rust removal. You can also use some solvents or a plastic cleaning pad.
ONTARIO KNIVES Educational Section
General tips, maintenance instructions, and care for your new Ontario knife
Basic knife maintenance rules:
Keep your knife dry
Keep your knife clean
Keep your knife lubricated
Keep your knife sharp
Store your knife carefully
Do not attempt to repair the knife yourself
The features and longevity of the knife increase with regular care. Familiarize yourself with the following tips:
Cleaning
Regularly clean the entire knife, including the blade, hinge joints, and locking mechanism. If possible, clean without immersing the knife in liquids (aerosol cleaners work well). If you have immersed the knife in liquid (water, soapy water, or solvent), thoroughly dry and lubricate the blade and moving parts after cleaning. Regular cleaning and lubrication remove adhered particles and light surface oxidation or rust formation, common in knives.
Alternatively, for blade cleaning, you can use chemical solvents like acetone, nail polish remover, alcohol, or paint thinner. Be cautious with these solvents, as some, such as acetone, nail polish remover, unleaded gasoline, or brake fluid, can damage the handles of some knives. Avoid strong cleaning agents containing chlorine (mostly laundry and dishwashing powders), which accelerate the steel blade's corrosion.
Avoid prolonged immersion in liquids (water, solvents, etc.). This can have harmful effects not only on metal parts but also on handles made of wood or other porous materials. Before using the knife to cut food products, clean with alcohol or wash with warm soapy water and rinse. Do not forget to clean and lubricate your knife again after finishing work.
Lubrication
Periodically, and always after cleaning, apply a small amount of lubricant to the working parts of the knife, especially the hinge joints of folding knives. Then apply a thin layer of lubricant over the entire blade surface. This prevents surface oxidation and moisture-induced corrosion.
Storage
Store your knife in a dry place (without the sheath). Rub the blade with clean lubricant oil 2-3 times a year to prevent rust formation (more often if the knife is near water).
TOPS KNIVES Maintenance and Care
Care and maintenance of your new TOPS knife
Congratulations on purchasing a TOPS product!
We have put a lot of effort into the individual handcrafted production of this splendid knife. To keep it in excellent condition, we have compiled a list of some general tips applicable to any high-quality tool or knife.
-
Some of our models feature a Polyester Hybrid Epoxy coating, applied electrostatically and baked in a kiln. This is the toughest and most durable industrial material we could find. Occasionally, small particles of the coating may be lost from the tips of the blade's teeth. This is not an issue, as the sharp abrasive angles of the teeth are designed for cutting hard materials, and the coating could eventually detach from the edge.
-
Our blades are made from the finest high-carbon alloy steel. For all high-quality knife steels (including stainless), there is a tendency for small spots of rust to form, especially if not dried. We pre-treat each blade with Tuf-Glide (developed and tested by US NAVY SEALS) to prevent rusting. With normal use, it is advisable to wipe down the cutting edges after finishing work. When you get home or return to camp, or when storing the knife for a while, another wipe will prepare the knife for your next outing.
-
The Kydex Sheath is specially shaped for your knife. It does not fit other models or types of knives. If during use it becomes dirty or filled with sand, etc., we suggest the following: remove the knife and pour warm water through the sheath's open end. There is a drainage hole at the bottom. If the exterior of the sheath gets dirty, using a combination of warm water and soap usually solves the problem. After washing, let the sheath dry completely before placing the knife back in it.
-
Sharpening: Heavy-duty field knives used for chopping do not necessarily need a sharp edge. For our knives, we create the best working edges. If you need a new factory edge in the future, it will be our pleasure to provide it to you at no charge. Please contact us before sending it.
Enjoy using your knife!
It was our pleasure to make it… You can rely on it to do work in good hands.All the best,
Mike Fuller
