ABSTRACT:
The invention is a handheld device for puncturing oil filters and thus allowing more retained oil to drain from used filters. An oil filter has several internal chambers filled with oil which do not drain by gravity from the filter unless the sidewall of the filter is punches. The device of the invention punches the sidewall of the filters, and provides a rack for draining the oil filters.
