Shock tools can include a rotary top drive box in threaded connection with an outer tube. A center plate tube can run through the center of the shock tool to provide a pathway for drilling fluid and/or mud to flow to the drill bit. A bottom tube socket box holding head can be attached to the outer tube and the center plate tube can be connected to a bottom drive socket. The bottom tube socket box holds a portion of the bottom drive socket within the outer tube. The center plate tube can be slidably engaged with the rotary top drive box. Multiple compression plates separated by compression pads are located in the tool to dampen the shock load by distributing the load across each of the multiple pads, thereby minimizing the load on any individual pad. This arrangement allows for higher load dampening lower failure rates.

Exemplary drill tools for placement in a drill string may include a body; a plurality of reamer cutters; and a plurality of ball and socket connectors configured to attach the plurality of reamer cutters to the body. Each of the plurality of reamer cutters may be replaceable by removing at least one of the plurality of ball and socket connectors from the reamer body. Each of the ball and socket connectors may be attached to the reamer body with bolts. Each of the ball and socket connectors may include titanium dioxide and/or titanium carbide coatings where the connectors interface with the reamer cutters.

A Dutch oven with an improved handle assembly is provided. The assembly may include a handle configured to removably engage a receiver on the lid of the Dutch oven. The handle may be used to transport a Dutch oven to a heating source and, once placed in the heating source, removed and stored so that the handle is not subject to heat while the Dutch oven is used for cooking. To remove the Dutch oven from the heating source, the handle may be reinserted into the receiver and used to lift the Dutch oven from the heating source. The Dutch oven may also include one or more retaining members to securely hold the Dutch oven's lid in place.
