In Beyond Oasis, you can do a variety of skills with your Ali Knife or with a Sword. However, they require an extensive button comination in order to work, and can take some time to get them to work. Here is some of the skills that I've found useful while fighting. Most skills can only be used with the Ali Knife.

Stab		Tap B	Ali Knife	Ali quickly stabs the enemy	1x
Slash		B	Ali Knife	Ali slashes the enemy	4x

Running Stab		Forward, Forward, Forward, B	Ali Knife	Ali runs and stabs the enemy many times.	2x per stab
Quick Flips*		Forward, Right, Back, Left, Forward, Back, Forward, B (add B for a 2nd flip, then another B for a 3rd flip)	Ali Knife	Ali quickly flips and attacks	6x per flip

*Directions with these can be a bit confusing. When I say "Right" I don't mean the right button on the D-Pad. To best describe what Right and Left are, just think of which direction to you his arms are facing. If his right arm is facing down, then Down is "Right". If his left arm is facing down, then Down is "Left". This is to make things easier to write no matter which direction you are facing.
