VG-10 vs 1095

me2 thanks for the explanation of carbide grain boundaries. i agree with dantzk8 that the verbal facts you mentioned makes a very good imagery in ones mind as to why metal can fail along carbide grain boundaries when carbides are large & not distributed uniformly in the alloy matrix. this info was fantastic since i have trouble thinking in 3 dimensions. m2 thanks again.dennis
 
No problem guys. You don't spend 72 hours in a week stuck at the bottom of a stainless tank that had a catastrophic failure without remembering what you were looking for. I'm sure if you do a search for sensitized stainless you can find some pictures and micrographs on line. They will be of 300 series stainless steels that have been damaged by heat or poor welding technique. Not all stainless cutlery steels will have these carbides, but if they are present, they won't really fit anywhere but the grain boundaries. Nothing like a picture to put things in perspective.

I use a custom 1095 bird & trout knife every year to clean Salmon and its never had a bit of rust. Just have to clean it after use and dry it. I dont even oil it. This is after 10 plus years

maybe because salmon had a lot fat in its fresh,
that's why you don't have to oil it

richkao although salmon do have lots of fat in the skin the acids in the blood & enzymes associated with the innards would be far more corrosive than any moisture in the environment. my 06 hunter a carbon steel has been thru many deer & after all these years no rust. while many novices may think 1095 melts in the rain, a simple fact is that if one cleans his knives when the task is finished you may get a patina but never any rust.

I clean the knife after every use. I dry it thoroughly as well but its nothing overboard. I usually clean the fish in the stream and lay the knife in the water during the process to keep it washed off.
