The parang knife falls into the same category as machetes and kukris. These blades are also a fighting weapon and come from areas where wood, bamboo, tall grass or vine vegetation is utilised. If you plan on spending time in this envireonment one may be appropriate. You exressed interest in a hatchet. With a large blade, it would be superfluous. I am not familiar with the hatchet he mentions, and don't carry one normally. You may want to take a look at the Swedish Granfors Bruk company. They are truly superb. The inexpensive all steel ( no wooden handle) Estwing is another option. A small saw is safer for most applications.
