One trick I've been using lately is the instant dash attack (hit direction and down on c-stick) when landing on a blade. There are many situations for it. Nice way to grab blade and surprise opponent at the same time, since in many cases you are landing with your back towards them. Most people will avoid the blade, but won't be prepared to block if you are landing with your back towards them
1. When running from opponent, jump, zdrop blade, and then dash towards them. This is nice as the zdropped blade covers your back.
2. Run up to opponent, RAR, zdrop blade, then dash on landing
3. Full hop, rising metal blade thrown downwards. Dash on landing. You can even face away from opponent, to make them think you messed up when throwing blade (although you need to move slightly in air to land on blade)
4. Probably many more I can't think of right now
