Carbon steel oxidizes much easier than "stainless" (there is no true stainless, just some more resistant than others). Carbon steel has many other great properties I won't get into here, but as has been said, a little oil (food grade like mineral oil is more appropriate of you will cut food, or it is a possibility) will help prevent overt rust. A forced patina (making the blade oxidize in a more limited and controlled way) is a way to actually further prevent rust. Exposure to various light acids for limited times helps, such as cutting citrus or soaking with vinegar.

Mora is a high carbon steel so it will stain over time. Does not take away from the quality of the blade. Mora's aren't meant to be pretty, they are meant to be used. If the rust freaks you out, just use a mild abrasive to remove it then use a light coat of oil on the blade. Any oil will do. I use olive oil since it is food friendly. It will last you a lifetime.

It's a high carbon blade. Clean it with steel wool and keep lightly covered with cooking oil.

Carbon steel is easy to keep sharp but it will rust very easily. Even wiping a blade with a paper towel leaves a little moisture behind. Coating the blade with just a tiny amount of food grade mineral oil can help prevent rust.

When you buy a new Mora carbon steel knife, I suggest that you heat a small amount of vinegar, degrease the blade (nothing too fancy needed, nail polish remover, rubbing alcohol, etc...or use a degreaser from the hardware store), and once the vinegar is hot put it into a glas container of some sort and (I use a mug) and fill it so the blade is covered. Wait about 15 minutes, and you will force a nice "patina" on the blade. It will be more resistant to rust and stains. Not as good as stainless, but whatever...it is a $9.00 knife. You can also use some mustard. Or you can put masking tape and make designs on the blade. Mora knives are a hobby unto themselve. Great product and good price.

The blade is made of carbon steel - not stainless steel. Carbon steel is generally easier to sharpen and holds a better edge. The down side is that it requires one more step to finish after usage. You will need to wipe a thin application of either mineral oil or vegetable oil on it to prevent rusting. For me the trade off is worth it as I prefer carbon steel. You can renew that blade to near original look by polishing it with a very fine grade of sandpaper or emery cloth. Even a scotch brite pad will go a long way to brighten the blade. You still finish with mineral oil. Good luck, they are fine blade of the "old school" of manufacture at a reasonable price. The blade is made of carbon steel - not stainless steel.

If you leave moisture on it the outside can turn a brownish color, its nothing to worry about and will rub off with a bit of elbow grease and a microfiber cloth, some people like to oil them a bit after washing, but the key is making sure its nice and dry before storing it again. There are products like Break-Free CLP or even WD-40 would work, you just want something to displace the moisture, a quick towel drying will likely leave a moisture film, I always dry with microfiber to avoid this. If you ever see the blade turning a more reddish color, that's rust and means you aren't keep it clean and dry.

It's probably just hard water stains. Mine started to turn a bit yellow and running some water with bleach through it for about 20 minutes fixed it. If you try this, be sure to run plain water through it at least a couple of times afterwards to get all the bleach out as I can't guarantee that bleach won't damage the materials that it is made out of.

There can be a mineral build up from them precipitating out of the water when it dries. Wipe it off with some white distilled vinegar & that should eliminate the "stains". You may need to let the cloth or sponge sit for a minute or 2 to let the vinegar dissolve the minerals. What the stainless mainly means is that it will not rust.

this is very unusual! normally this stuff turns black in a very short time over all surfaces,painted or rusty. i've been using this stuff for years and i highly recommend putting down some rustoleum metal primer over all treated surfaces,no matter what the label says about not needing any primer. did you shake the container enough,i wonder?

Haven't had a problem with rusting. Sounds nasty but touching your face and then putting the oil of your skin on the blade helps so much

I took the blade off to clean it. Be advised the blade is very sharp. Watch how u handle it.

Well wipe it off at after usage and put some oil on the blade and you won't have rust problems. I keep mine stored in its sheath and I have never had rust

Yes. Actually, any carbon blade will rust if you get it wet and don't wipe it off. You can prevent the rust by simply using a light oil like mineral oil on the blade only for this knife. If it does get light rust on it, you can take it off with a sand paper like 400 or 600 grit. If you go perpendicular to the edge with the sandpaper, it will look new again.

I am not sure. When I mix this with water it is a rust color. It may also dry out if used and it is wet unless a moisture agent is introduced.

I 're used mine just cleaned it up didn't affect the blades at all. The blood trail was amazing didn't even half to bend down to see it.

The edge of the blade is stainless to begin with. If you're not careful you could take the color off higher up.

The discoloration is probably caused by it not being oiled correctly. I highly recommend you read up on oiling your cutting board, but if it turns out you've oiled it correctly and didn't put it in the dishwasher or anything, I'd return it for another. When I get a new end grain board, I oil it every day for a week, then at least once a week for the next month, then as needed (it starts to look dry). This will ensure that your investment is protected.I have a wide variety of boards, from this one, to side and end grain teak and I have to be honest - this one is the best. Good wood cutting boards require maintenance though. The discoloration is probably caused by it not being oiled correctly.

Yes, tiny bits of metal scraped off the edge of the blade when you sharpen it, but that happens to some extent with all sharpeners. I just rinse the blade in water and wipe it on a kitchen towel before using it.

Currently on my second razor of this model. Neither rusted. My only advice is to remove the used razor after use. A wet, used razor left inside will rust quickly and make a mess.

Not normal. Use a flashlight and check for rust. Return to Amazon if you are within the date to do so; otherwise you will have a difficult time to get a refund from Mastrad, if any.

I wondered about if it was dyed since when I washed it in still water, the water changed its' color. I am wondering if I should throw it away.
