Leaves a tip — which they all have each in their own way (8)
I believe the answer is:
icebergs
I believe this clue is a double definition.
'leaves' is the first definition.
(ie iceberg lettuce leaves)
'a tip which they all have each in their own way' is the second definition.
(as in 'the tip of the iceberg')
(Other definitions for icebergs that I've seen before include "Huge masses of frozen water" , "Masses of frozen water and lettuces" , "Arctic sea hazards" , "Large masses of frozen water" , "Large masses floating at sea in polar regions" .)
