Earlier quoted context omitted.
Maybe not if its the case that your use of the broken tool would result in the eventual undoing of your work. Like, lets say your staple gun is defective and doesn't shoot the staples deep enough, but it still shoots. You can keep using the gun, but it's not going to actually do its job. It seems useful and functional, but it isn't and its liable to create a much bigger mess.
So to continue the analogy, if the staple gun is broken and it requires you to do more than a working (but non-existent) staple gun BUT less work than doing the affixment without the broken staple gun, you would or would not use it ?
If I don't use it, then the tool is not used and provided no benefit...
