Department of mixed metaphors

The Obama administration is proposing legislation empowering the President to propose cuts to each budget passed by Congress, which Congress would have to vote up or down as a package. Somehow I doubt that Peter Orzag soothed Congressional fears of executive encroachment in his presentation to reporters:

White House Office of Management and Budget Director Peter Orszag said that while the new presidential power would not be a panacea for the government's spending excesses, it would "add to the arsenal of tools" available to reduce spending.

Arsenal of tools?  Does Orzag want to shave a few rough edges off Congressional budgets or blow pieces off them?
