Hi folks, I'm a newbie but I've recently gotten into cooking and I love it. I found that the cheap knives I had in my kitchen could never hold and edge and would hinder me from cooking at my best or even wanting to cut things in the first place. So I decided to invest in a good knife. I read a lot of reviews and watched a lot of videos and decided to put some extra money and get a Konosuke HD2 240mm Gyuto. I read that people have had the HD1 version for years with no issues so I thought this would be a good knife to have for long term. Since I've gotten it, I've washed and dried it with a towel after every use (the water might have been too hot?) . I don't let anyone in the house use it (i hide in my room) and I have done nothing but tried to take absolute care of it. But unfortunately its not looking so good. I've had the thing maybe two weeks and it has these smudges (which are turning brown.. oh god is it rust WHAT DO I DO!?) and other water-looking marks. Overall it looks very used and worn and I probably don't even have a complete hour of chopping on this thing. I'm so disappointing and discouraged right now. The knife was $250..a lot for a uni student like myself but I figured I should spend a lot since I may be using it for years. I was reading of what I could do yesterday and I was told to get something called 'Bar keepers friend' ( a stainless steel cleaner) but it didn't do anything, even while scrubbing with a coarse sponge. What can I do to get my knife looking like new?
