Also, one could do pretty much your entire, favorite trapping hand course with one or two palm sticks in your hand.
Early Aiki-Jitsu material covers a lot of palm stick work also. There was once an emphasis on palm sticks and that has been left over in many of ready stances and fighting stances.

Also, the closed folding knife? ....is a palm stick! Providing using one in this manner does not hurt your hand, as many knife designs will. We cover this in Level 7 of the knife course.
http://www.hockscqc.com/shop/product131.htmlSo, when you select a folding knife, think about how it feels in your hand also as a palm stick. AND that my friends is a tip you will not see many so-called, knife experts advise. Why? Because so few worry about the harsh realities of stress quickdraws and their subsequant failure to open the folder when attacked suddenly - which often leaves you with a closed folder in your hand and leads you to use using the knife as a palm stick like weapon.
(as an aside, another reason to pass on the karambit- usually the karambit knife's dull edge, when closed, extends way far out of the handle to facilitate the curve tip of the knife. When you grip this closed karambit knife as you would a palm stick the dull side of the blade hurts your hand - fingers or palm. Then, start hitting things with this fist and watch your hand become quickly become hurt injured, disabled! ......open trash can lid...deposit karembit)
I use my combat invading/trapping hand outline (form UC level 9) as a closed folder knife/palm stick workout.
As a cop I carried a Cold Steel Tanto folder. It was a big rascal, but it fit well in my hand when closed.
