The chart in their catalogue shows 20CV as having superior edge holding and corrosion resistance, but not being as tough or strong as the S30V. However, since I am more concerned about edge retention I think I will get a new blade using the 20CV.

However, I wonder if you have seen ANY chipping of the 20CV edge?

Hi Larry,

It all depends on the specific manufacturer and its preferences in heat treatment for a particular application (knife model).

I made a mistake, it was necessary to more precisely indicate that it was on the knives that Hinderer S35VN was prone to chipping and also to add - at small angles of sharpening (20-25 grad and less). If take, for example S35VN in the treatment of Chris Reeve, she does not give chips, she is plastic enough.

As for the Benchmade, I can not say something about these steels in their performance, because I did not have them and my friends also.

I did not see chips with steel 20СV on knives Hinderer, GrayMan and Linder (Linder use M390, but it's the same thing). But I saw chips on the knives of one local manufacturer, he did 64-65 units of rockwell, then he began to harden 60-62 units and there were no more chips.

Warren - great info, thank you! smile
