Kato's Crux is a three ball
pattern established by
Idiosensory. The trick simultaneously combines high vertical throws with
rapid catches, creating a structure sort of similar to that of the Sandbox Shuffle.
Kato's Crux has no obvious peers, therefore it is an orphan pattern with no
clear prerequisites beyond basic familiarity with three ball juggling.
To begin learning Kato's Crux, start with one ball in each
hand. Cross your non-dominant hand over your dominant hand and then rotate
your non-dominant hand so that your palm is facing downward. Then make a fairly
high throw from your dominant hand along the center of your body while basically dropping the ball in your
non-dominant hand (you should still give the ball a bit of upward movement). In
the same motion you are going to uncross and then recross your arms such
that your dominant hand is on top, catching the "dropped" ball with your
dominant hand as it recrosses. The high ball will then be caught
under-the-arm by your non-dominant hand.
As shown, practice this on both sides. To add in the third
ball, start with two balls in your dominant hand and one ball in your
non-dominant hand. Cross your arms so that they are in the same starting
configuration as step one, and then make a fairly high under-the-arm
vertical throw from your dominant hand along the non-dominant side of your
body. As this ball reaches its peak and begins to descend, you are going to
perform the same throws and catches made in step one, except as you
uncross your arms you are going to snatch the first ball you threw out of
the air before recrossing your arms.
As shown, practice this on both sides. You have essentially
completed one full cycle of Kato's Crux. To connect two cycles together,
just make a fairly high under-the-arm throw from your non-dominant hand such
that it mirrors the very first throw you made (with your dominant hand)
before catching the center ball. This will set you up to do another cycle on
the the opposite side of your body. Kato's Crux is not a particularly
difficult trick to perform, though it will take time to become comfortable
with the various throw heights.
