Scout's spike (4,3)
I believe the answer is:
tent peg
'scout's spike' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tent peg that I've seen before include "Fastening for guy-rope" , "used to make a guy secure" , "Canvas fastener" , "A guy could get attached to that" , "What guy is steadied by" .)
