My anecdote on thorne K2 is that I got a lot less bruising for the last couple of years when I took it. Various amounts, 1-4 drops/mg, every 1-3 days. Recently I didn't take it so often, and noticed a few bruises again, and resumed. Those bruises are healed, haven't spotted new ones. Always lots of potential factors, but this could be one of them.
But I've only taken a modest amount of aspirin on a sporadic basis.
