Blubberknife (also known as Many a Wonderful Picnic Has Been Ruined by Blubberknife) is the third studio album released by the Australian experimental group Severed Heads, originally as a C90 cassette tape. The first approximately 200 copies were packaged inside cassette cases that were spray-painted silver, stuffed with loose cassette tape and had parts from the insides of television sets glued to the front of the case. Five copies were specially packaged inside fully operational calculators. It's the first album by the group to feature contributions by Stephen Jones, and it is also the first recording by the group to catch the attention of UK label Ink Records, who helped release Since the Accident a year later and reissued Blubberknife in a standard cassette case with new artwork in 198
