发明名称 Adjustable lightweight camping mallet
摘要 Adjustable weight camping mallet having a hollow head with interior chamber and access opening that can be selectively covered and uncovered. When uncovered, the access opening permits insertion of weighting material into the interior chamber to increase weight of the mallet head. Covering the access opening retains the weighting material within the interior chamber. The adjustable weight mallet has minimal weight, such as while backpacking, when the interior chamber is empty. When the mallet head is filled with weighting material (e.g., sand, water, wet sand, dirt, wet dirt, rocks, lead fishing sinkers, pocket knife, batteries, or combinations thereof), the weight can be increased by more than 50%, 100%, 200% or 300% depending on the volume and/or density of weighting material.
