Knight Oil Tools has developed a new product line featuring the Megaton Drilling Jar with Ulti-Torq connection and the Megaton Energizer, which maximizes the drilling jar. The products are designed to help free stuck drillpipe by providing an impact or jarring effect upward or downward on stuck pipe.

Incorporating features of both hydraulic and mechanical drilling jars, the design combines both hydraulic time delay release and a mechanical lock mechanism in one relatively short double-acting jar.
