There are many versions of Gojushiho/Useishi, but a distinctive feature of the kata is its repeated sequence of spearhand techniques--typically in conjunction with some form of osae-uke (pressing receiver). I put together this short video looking at how we perform the sequence, and a basic application for it.
The initial technique is very "what you see is what you get" bunkai--parrying a right punch down and striking over the top with the spearhand. The next movement assumes that the attacker has blocked your strike, so you must clear the obstruction and strike again. In our version, the pressing hand circles upward, while others circle downward. This does not change the concepts being applied, although it changes the way you clear the obstruction. Nothing special, really, but simple and to-the-point.
