What I've heard people say about Nitro V is that it's got similarities to a few different steels that can take a really sharp edge. No one says it's hard to sharpen, no one says it's soft either. Sounds like it can take decent hardness.
How Nitro V compares to some other steels available thru Drop:
Note that this is a molar mass analysis, not an analysis by weight. If you're hazy on your high school chemistry, this just means that the graph is trying to track the ratio of atoms in the alloy matrix, not just the weight.
Here's a shot of the analysis.
Some, but not a ton of carbon. A standard amount of chromium for a stainless steel. No molybdenum at all, no tungsten. It's got traces of vanadium -- frankly, numbers which you might find in a lot of runs of non vanadium steel if it were produced on equipment that also made vanadium steel. As you can see, the 'super steels' in the graph, M390 and S35VN, and even that old workhorse D2, all have significant amounts of vanadium -- it's known to contribute to wear resistance. No copper, no nickel, no niobium, but as the name suggests, Nitro-V is the only one of these steels to have any nitrogen infused into the steel. I know a little less about how nitrogen steel behaves under load and over time than I would like to know. It seems to be one of those things like sulfur that at some concentrations can be helpful and at others, a problem. The summary also notes that the figures from Nitro V are from the manufacturer and seem a little too precise to come from random measurement, so frankly the ultimate composition of Nitro V might be somewhat different.
Overall, the zknives summary suggests Nitro V is most like AEB-L or Sandvik with a few tweaks. That isn't half bad company.
