Hello,
Sorry YKW,
But there is indeed a ridgehand. In Shaolin we call it ZanZi Shou, or Zan shou.
It uses the side of the knuckles.
It is usually done palme up.
In Shaolin we mostly use it by using the third knuckle side, the furthest (and weakest) knuckle. I know this sounds strange but it is very fast and whippy and used to attack the adams apple, eyes or nose. Similar techniques can be done using the middle or primary knuckle as well, but range and speed are reduced.
Often we shape the weapon to the specific target, so there are many small variations on common fists for use against specific contours or surfaces.
Also, I learned in a XInYi style once, a ridge hand, like an axe blow downward, but with the ridge instead of a chop. It is more difficult to block, but a little dangerous as the force goes against your elbow so you can break your own arm.
