Running amok with it involves risk (4)

I believe the answer is:

kris

I'm a little stuck... Click here to teach me more about this clue!

'running amok with it' is the definition.
I can't tell whether this definition defines the answer.

'involves risk' is the wordplay.
'involves' is an anagram indicator.
'risk' with letters rearranged gives 'KRIS'.

Can you help me to learn more?

(Other definitions for kris that I've seen before include "Malayan dagger" , "Malay dagger, wavy blade" , "weapon" , "Malayan slashing knife" , "Malaysian knife with a scalloped edge" .)

I've seen this clue in the Evening Standard.
