Suffering regular losses, use plan to upload flexible tool (7)
I believe the answer is:
spatula
'tool' is the definition.
(spatula is a kind of tool)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for spatula that I've seen before include "Flexible knife-like instrument" , "Thin tool for mixing or spreading soft substances" , "Tool with broad flexible blade for spreading and mixing" , "Kitchen implement with a flat, blunt blade" , "Tool with broad flexible blade - alas, put away" .)
