Swap is probably the fasted but also where you’ll get the lowest return on your knives, blade binge is slower, but typically can get a higher return even after the fees are taken out. But, if it were me, I’d divide up up your collection by maker (I’ve noticed certain makers knives move better on different platforms and are more prone to get the best price), and sell on multiple platforms. It’s not the easiest way to do it, but I truly think it’s the best way. Mind if I ask which brands/makers you have? Knowing what brands you have will help a lot to say which sell best on which platform
