RC hardness for taking a beating???

Rusty didn't you just buy a kiln? All this rockwell talk is just going to make you want a tester next. Get out while you still have money :D

Ha! I did indeed buy a kiln... still reading up on it and haven't even heated up coffee with it yet. I've given up on money long ago, lol. as stated in a recent post, I'd make more money opening a hotdog stand.
 
Jerry Hossom has said that pasting 3V helps with corrosion resistance. There has also been some discussion as to whether or not low temperate tempering of 3V is a good ro "bad" thing not only for performance, but also for corrosion resistance. The same discussion pops up about some stainless steels. I can't rrmebr which, but either Nathan or Butch did a little research with 3V a while back dressing that very topic

When stone washed 3V can be fairly corrosion resistant. It certainly can take a beating.

Passivating 3V is never a bad idea. It helps clean and protect the steel and when done right, it looks really cool. (polish a 3V blade to 1500 grit or higher, then passivate/etch it long enough, and it will look like chrome under a light grey filter... try it, you'll like it)

But if really high corrosion-resistance is a serious requirement, you're better off with Elmax or CTS-XHP. They're both very tough and I trust their durabilty even in a big/long knife.

No matter what steel you use... the finer the finish, the better it will resist corrosion. Stone-washing or tumbling is not the best option in that regard.

My approach is that 3V should be HT'ed for the best structure and highest overall edge-stability. The work and research of makers like Nathan Carrothers and Jerry Hossum (and the pros who do their HT) have proven that time and time again. The stuff just plain works. 3V's relatively high corrosion-resistance (WAY better than "plain carbon" steels, about equal to D2, but certainly not "stainless") is just a happy bonus.

p-a-siv-ate" you say? I am sooooo trying that. just normal etch? how high exactly... how long to hold it? sorry, just so many questions. SOOO agree as well on the finishes making steels less corrosion resistant. I have had 440c come back from the jungle rusted (surface rust) because I had a bead blasted finish that held water a bit longer than smooth finishes. Also had a felt liner in the sheath which obviously kept moisture in as well. fixed the sheath and tried it again the next trip to the tulips and he had better luck.
