I've decided to sell my knife and purchase a PAX 2 because I think it is more worth it. My knife is Stat Trak Bayonet Doppler Phase 2 Pink Galaxy with a Float Value of .0002 which is #3 in the world. I have had offer of 220 keys but I think I just want to sell out.
Float value is the wear value of the skin. For example, some skins can be Factory New but not look all that great, this is because they have a high float value.
