Does the Golden Knife have different stats than the regular knife?

Question

When you are at the last level of the Arms Race mode, are you on an advantage or disadvantage with other players with a normal knife?

Answer 1

No - the golden knife has the more specific purpose of ending the Arms Race - the knife is gold to convey to the user the difference between killing someone with a knife to steal their level and killing someone with a knife to win the game.

It provides you with no advantage or disadvantage other than winning the game if you kill with it.
