Abstract: A portable and collapsible hand tool is disclosed wherein successive small samples of suspected contaminated earth soil may be directly deposited in a sampler bottle, following selective penetrations and extractions of the soil. The sampler is characterized by a substantial balanced mass which is vertically disposed above the sampler tool head, the head having in extension thereof a soil probe column which forms a tube of reverse draft, the same being interconnected to an inverted sampler bottle which is retained within the head where it is shock protected.
