I like knives made of K390 or S90V but lean towards the latter S90V. They seem to be two knives in the same pod but the S90V is harder taking longer to sharpen but it holds an edge and doesn't corrode. Thoughts?
K390 steel equivalent
The closest steel to our K390 would be the
S90V Stainless Steel, in exception for corrosion resistance (
S90V offers a better corrosion resistance compared to the K390), they both offer great edge retention and hardness due to 9% of Vanadium in both steel, Same for the wear resistance, and they both fall in the same price range of high-end steel.
S90V
According to the chemical composition and the HRC of the steel, the CPM s90v Steel has the following features:
CPM s90v Edge Retention: With a high presence of vanadium and carbon, s90v steel offers extreme edge retention (might be the best in the steel).
CPM s90v Corrosion Resistance: Great Corrosion Resistance due to 14% of Chromium, which makes s90v stainless steel (Once steel has more than 10-12% of chromium in it it’s considered stainless steel).
CPM s90v Wear Resistance: Excellent Wear Resistance, with 9% of Vanadium, the steel is very hard and durable.
CPM s90v Sharpness: the better steel can hold an edge, the harder to sharpen it, the s90v is very hard steel, so sharpening or grinding won’t be an easy task.
