This power strengthens and reinforces the structure of an object. Some Jedi have discovered that is can also be used to weaken objects in a similar manner. Using the Force, the Jedi reinforces the inter- and intra-molecular bonds in the object. (Amplification of the strong and weak nuclear forces, I guess :). The object has the same density (more or less), volume, and mass as before, but it takes more energy to break the bonds holding the object together. This is a relatively basic skill and is usually taught early in a Jedi's studies. This reinforcement strengthens the object versus shearing forces, stress, or disintegration/disassociation by high energies. Thus, a 1D staff Strengthened at the Very Difficult level would now have a Strength of 6D - enough to resist a Lightsaber, most of th
