Hopefully your oven can go up to 1520 in 15 minutes, then I'd quench as soon as it gets there. 30 minutes above 1400 will cause some unwanted grain growth even with the vanadium I would think.

Because of your oven you're going to have to experiment some to get a decent knife without much grain growth. Make some pieces to test and break, like I said proper grain should look like grey velvet, no crystals, not even tiny ones if you can see crystals with your naked eye then the knife will tend to brittleness.
You wouldn't have a forge would you?
I have a 2 burner gas forge, haven‘t gotten around to using it so far.
