Case CV is a perfect example of how something simple sometimes works far better in the real world than something that looks far better on paper. There are some very complex and advanced steels on the market, than on paper will output and last better than some simple steel like Case's CV. Simple 1095 series and 1085, and other simple steels work well in most real world pocket knife use as the so called better steels.
I remember Bob Loveless making a big deal out of the fact that the steel he was using was formulated for the blades in jet tubing engines, and will hold their temper at 700 degrees. This was the 1970's when knife makers were making outrageous claims even than about super edge holding. If I'm someplace that it's 700 degrees, I'm definitely not going to be worried about how my knife is holding up. The supporters of the super steels like to make a lotos, like how large a herd of deer can be field dressed without having to sharpened. After a while it gets a little silly. But what isn't silly is how long or difficult it is to sharpen that blade.
Yes, there are steels out there that will hold a cutting egg a lot longer. But when it comes to sharpening, will be a giant pain in the south end of a northbound person. Case CV, like the SAK steel, can be stropped back to a razor edge in very quick time with almost anything on hand. A cardboard back of a notebook, coffee mug, top of a car window, piece of brick or smooth stone from a creek, back of a belt. Most of us that are not born to the manner, and have a life of wealthy self indulgence, have to go to work. That means we leave the house in the morning, and don't come home until evening. Or we may take a weekend trip. What happens when we are away from home and our knife needs sharpening? Since most of don't carry a large home based gadget with us, we need to be able to sharpen that knife on what's around. A simple steel like CV is great for that.
I can remember being on a trip up visit some of mom's family in Patterson New Jersey, and dad had helped Uncle Paul with something that morning. He'd cut some rope and then felt the blade on his peanut and kind of made a "Hmm" sound. Later that day, after lunch, he finished his coffee, and turned the cup over and honed his peanut for a minute, felt it, and was satisfied it was serviceable again.
Case CV is a reminder that there is some truth to the old saying; sometimes less is more.
