How good is the steel 4Cr13MoV ?? Answered

I've got a knife made out of it, and I was wondering how good it is, I know its some sort of Chrome-Molybdenum but this one has got a hint of Vanadium which I know some tool steels are made out of, Could someone please shed some light on my question??

8Cr13MoV (any of the CR series)

These are Chinese-produced steels that recently started showing up in
Chinese-made knives. 9Cr is the top end of the series and is quite good
– as good or better than AUS-8. Type 8Cr, the more common formulation,
is worse than AUS-8: a little more prone to corrosion and not quite as
hard. It is very cheap though, and when ground appropriately it can be a
real winner from a value standpoint.

Note:Don’t bother with anything less than
8Cr in this series. Steels 7Cr and below aren’t worth your time or
money. They lack the carbon necessary to hold an edge, even during mild
use.

CrMoV is a steel...

"CrMoV steel is a heat resistant steel typically used in applications such as shafts and fasteners used in high temperature service.

The chromium is used in this steel to increase resistance to corrosion and oxidation, to impart high temperature strength and to increase the hardenability. The molybdenum addition also imparts higher hardenability and increases high temperature tensile and creep strengths. The vanadium addition inhibits grain growth during heat treating while improving strength and toughness. This steel is referenced in the industry specification AMS 6304."

If it wasn't, would they have made a blade out of it?

Even blade steels are only "good " blade steels if they are heat treated very carefully.
