"Why do most folks here love CV, (chrome vanadium), steel? I know it was one of the better steels in the old days and still is today but why do you folks love it so much now?"
Because it IS one of the better steels around?
You did kind of answer that yourself. But lot of people like it now because it just plain works out for a cutting tool. Yes, there are modern stainless steels that will work. But like most things in life, there are trade offs. I can remember the old days when stainless steel was not worth a tinkers d--m, and nobody who used a knife on a daily basis would bother with the stuff. Carbon steel was the universal knife steel when I was a kid. Stainless was used for flatwhere that you used to eat dinner with.
Today you can get a whiz bang stainless that will outcut some carbon's, but one of the trade off's is that most knife owners can't easiely sharpen it. Cv or plain old 1095, in addition to being a longer lasting cutting edge in general, will sharpen up from dull a lot faster. I've carried both in my lifetime, but in general, for general cutting use in the real world, I much preffer carbon.
I've had identical knives in both steels, and while the stainless was okay for most days, I could tell a difference if I did some unusual dirty deeds cutting. Between a stainless peanut and a CV peanut, there was a noticable difference if pushed. Between a carbon number 8 Opinel and a stainless number 8 Opinel, I could tell a bit of a difference.
With most stainless, as the RC goes up, the abrasion resistance seems to go up as well. Most people seem to having enough of a problem getting a dull knife sharp again without adding this in on them. For a great deal of human history, people have managed to do amazing things with plain old carbon steel.
For thirty years, I watched Bill Moran try and experiment with just about every type of steel a knife could be made from. Bill was the kind of guy who was always trying to find the better steel. He didn't like resting on his lurals. He'd forge, stock remove, bend, test impact, wear on edge, and even have the grain analized. He never found a stainless steel that could stand up to a well made carbon for the American Bladesmith Society tests for master smith. Believe me, he looked.
For the basic business of cutting, seperating something at a molecular level, it's going to be very hard to beat plain old carbon steel for many years to come. I don't beleive it is by accident that Jeff Randall's people use 1095 for most of thier knives. Look at some of the hard use "survival knives" that get great cult following. Not much stainless around.
As for the rust issue, I believe it is greatly exagerated. Yes, I hear people saying how they live in a humid environment and their knives rust right in thier pockets. I don't believe it.
I grew up in a humid environment. The Chesapeake bay is one of the bigest salt water bays in the world, and summers in Mayland can be so humid, something a mile away can have a blue haze around it. But too many watermen made their living on the bay with carbon steel knives that didn't rust. Yes, they stained, but they didn't rust. Even when tossed in a tin bucket and let sit, they just got black as the Earl Of Hell's riding boots. They got wiped down every night, and in the morning they got touched up on a stone while heading out. As a kid, I never saw a stainless steel knife in the hands of men who really did use a knife every day. If you wanted a serious knife in the 1940's and 50's, you got a good carbon steel blade. To some degree today, I think that still stands. If you just wipe off your knife every day, it's not going to rust on you. It may stain a bit, but that's going to protect it in the long run. I understand how some people freak out these days if they find a spot on their knife. Get over it and move on. A little color on your blade is not going to hurt anything. I remember the old timers when I was kid, getting a new pocket knife, and sticking the blade in a potato overnight to induce a protective patina.
Stainless steel has come a very long way in the past 40 years. In some cases the very high end stainless may even beat out carbon for edge holding. But then you get some negative qualities that are not worth the trade off. I believe that CV is still so popular, is that for OVERALL use in a cutting tool, it's very hard to beat. CV and plain old carbon like was used by Schrade, had such a loyal following by working men, because it gave them the best 'overall' preformance from a cutting tool.
I don't think it's changed much, exept for the urination contests by the knife snobs that keep the knife manufactures coming out with the wonder steel of the month.
I'll keep on with old carbon steel blades.
