How sharp does a crowbar need to be if I want to open a door with it?
<|assistant|>
A crowbar doesn't need to be very sharp to open a door, but it should be well-made and sturdy in order to provide the proper leverage for the job. It should have a handle long enough to provide you with good leverage, and the bar should be wide and sturdy enough that it doesn't bend when you apply pressure. The edges of the crowbar should be tapered for better gripping and prying.
