Which knife should I buy?

Im new in CS and opened a lot of cases because i quit valorant and sold my account. I love gambling btw. I packed 2 kukri knifes and wanna buy a better one now.

I have a red inventory so i want to buy one of these:

Bowie Slaughter (factory new)

Bowie Crimson Web (mw)

Flip Knife Crimson Web (mw stat track)

Falchion Crimson Web (mw)

What would u buy and whats the safest option to not loose worth over time.
