Wound, as if new, risks being cut by my bladed tool (5,4,5)
I believe the answer is:
swiss army knife
'bladed tool' is the definition.
I know nothing about this answer so I can't tell whether this works.
'wound as if new risks being cut by my' is the wordplay.
'wound' is an anagram indicator (wound can mean twisted or turned around).
'being cut by' indicates putting letters inside (some letters cut their way into a word).
'as'+'if'+'new'+'risks'='asifnewrisks'
'asifnewrisks' with letters rearranged gives 'swissarknife'.
'swissarknife' placed around 'my' is 'SWISS ARMY KNIFE'.
Can you help me to learn more?
(Another definition for swiss army knife that I've seen is " potential weapon".)
