I stay like a foot from the razorwire, pull out my cutters and hold down the mouse button you get a animation and 10-20 seconds later you have a small section of razor wire that is cut and able to fit 2 people side by side.
For fences, same thing! Have a "wreck" and a normal fance, walk up to the fence 10-20 seconds later you have a hole!
PS: Give them to the engineer
