this says a lot about our society

"Supporting people you like with donations feels good given the times we live in."

Nothing is ever fun, it's always hard.

I get a lot of satisfaction out of hunting down build errors and murdering them.

Like what Puff Daddy/Diddy did to LZ's Kashmir? Yeah, I agree. Even more insulting is when retards like it better that the original song

Kong Kian Sin makan tahi babi.

Mondays are pretty boring.

Well, it's fun how this thread has so many replies, but probably no one would ever make the challenge of getting something out of the posts in the middle. I think that most of the things that people write here are lost, even though they are public to anyone at anytime. One could say that there's some function that describes how the last person writing is the one that reads/responds the last 10-15 posts and so on, though, changing that reader for every post that is made. Like some type of ever arming and disarming train, flowing continuously on time, without ever arriving to a destination.The amount of information people gets from this thing, I mean, as in "the total of the data that's written in here cannot reside in the mind of a single person, but in a flow of collective behavior". One could argue that there's a general expression that describes that behavior in all forums like this, as well. I like when conversations happen, so that would be an interesting case of study; but I've also seen that most of the time it is this continuous flow of unrelated info.

Anyways, I'm new here, so; that's what I'm thinking,,,,,

People's personalities don't change.

Mother should blame God. I am not a fault. I was never at fault.

For better or worse, time goes by so fast

leadership is a dumb word

Mother is delusional. If God truly had any sense of decency - any at all, then he would have done the right thing by making sure QC Holdings Bhd renew employment contract in Limbang. None can expect me to continue paying the house loan after I ended up getting the worst part of the job in the dump that is Tanjung Manis. After all, it was never my idea to move in the first place.

Without being excessively long-winded about it, because it can easily turn into a long post... there is this book called The Razor Edge Book of Sharpening, from the 80s, which used to be one of the bibles of the subject. It's still worth reading, in part to see how radically the practice of sharpening steel implements has changed in only 30 or 40 short years. Back then, 1200 grit synthetic stones were the new hotness that few people used. Now, 1200 is considered basic, and people have entire *stacks* of 30k-50k grit synthetic Japanese waterstones to review for Youtube, with new ones coming out all the time. Many people don't realize how very recent this is, and how for almost all of human history sharpening was much simpler.

Anyway, there is one thing in particular which concerned me. TREBoS addressed the question of whether stainless or non-stainless is better for a knife steel. The conventional wisdom, then as now, was that stainless steel doesn't hold an edge as well. That was before super steels like S35VN, so read it as applying to conventional stainless knife steels like 440A or AUS8. In their testing, the authors found that stainless got just as sharp, and held the edge for 4x as long. How do we reconcile this?

Metallurgy has an answer. There are three types of wear you find in steel: abrasive wear, adhesive wear, and corrosive wear, and resistance to abrasive wear depends on the amount and types of carbides in the steel. People who are cutting wood or cardboard are getting abrasive wear in a dry environment. The authors of TREBoS worked as consultants to the meat packing industry, and did their tests there, where you are cutting soft material in a wet, salty (blood) environment all shift long.

What makes a steel stainless is mostly the free chromium in solution, which forms a passivating layer of chromium oxide on the surface. Other elements, including nickel, also contribute. Carbon ties up chromium in chromium carbides, which is why D2 tool steel (1.5% Carbon) is only a semi-stainless despite being 11-13% Cr by mass. The heat treat also matters because it affects the amount of carbon that ends up in carbides vs the martensic structure, which is why some knives made out of D2 or 3V are highly corrosion resistant and others are not.

Compared to zero-chromium high carbon steel, stainlesses have more of the carbon in chromium carbides, which are softer than other carbides. Sharpening also works via abrasive wear, so it fits with peoples' typical observation that AUS8 is easier to sharpen than 1095, but loses its edge more quickly - in a dry, abrasive environment.

Now, what I'm really thinking is, since you can make super stainlesses that are more abrasion resistant than D2, but people still like 1095 and O-1 for the ease of sharpening, why not design a stainless alloy to have exactly the abrasion resistance of 1095, so it will have the same ease of sharpening and edge holding capability, but in addition be corrosion resistant. I think that would be very popular.

I'm a complete novice when it comes to this subject; I'm curious to what degree background radiation - if any - from steel forged post-1945 has on the strength of a blade. Do you happen to know off-hand?

I do know steel prior to that period is prized to the point of shipwrecks being desecrated to salvage it for use in sensitive radiological and medicinal instruments, but I've always wondered if this extended to more general uses of steel as well.

Oh - and by the way, I just wanted to say that you have quite an impressive breadth of knowledge concerning blades!!

When last did I postq

Oh come on, mate. That's just a copy paste of my post on the same page. It's cool, if you agree with the sentiment, but you could've at least used your own words to describe it.

Imitation is the sincerest form of flattery, I suppose.
