Sharp ends, perhaps, but maybe no tips (6)
I believe the answer is:
points
This could be a double definition.
'sharp ends' is the first definition.
'points' can be an answer for 'ends' (point is a kind of end). I'm not certain of the 'sharp' bit.
'but maybe no tips' is the second definition.
'points' can be an answer for 'tips' (I've seen this before). I'm not sure about the 'but maybe no' bit.
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for points that I've seen before include "as setter does" , "Decimal dots" , "Tips" , "Indicates using finger" , "Railway track with two movable rails" .)
