which can be beneficial in altering the balance point of the tool since the blade of a knife or sword is often quite heavy compared to the handle. Adding weight to the handle of a knife or sword to offset the weight of the blade moves the rotational balance point back toward the hand where it can be more easily manipulated to great effect, making for a nimble, agile tool. In general, a forward-balanced blade excels at chopping but sacrifices agility and ease of manipulation; a centre or rear-balanced blade excels at agility but sacrifices raw chopping power. Knives and swords intended for specific purposes will usually incorporate whichever design is most suited to how the tool will be handled for that specific purpose. A partial tang knife or sword is generally not able to leverage as much force against the resistance of material being cut as a full tang design would allow. This limits the amount of force which a user should apply to the handle of such a weapon. Such designs may be optimal in light-weight knives or swords designed to be kept extremely sharp and used to cut less-resistant materials. Scalpels and Japanese samurai swords are perhaps the most well-known examples of such tools. Common tang styles found in swords and knives Most of these design styles can be used with full or partial tangs and the use of one does not exclude the use of another. For example, a sword may have a hidden, encapsulated, rat-tail tang. A push tang is inserted or pushed into a pre-made handle and fastened in place. An encapsulated tang has the handle material molded around the tang itself and fastened in place. A hidden tang is fastened within the handle such that neither the tang nor the mechanism by which it is fastened is visible on the surface of the handle. A hidden tang may be accomplished in a number of ways. The simplest way to accomplish a hidden tang is with epoxy. A more sophisticated method is to construct the tang with a small protrusion (or a protrusion may be welded onto it) which fits into a notch in the handle, preventing the blade from being withdrawn from the handle. Another common method is to cut bolt-threading into the end of the tang whereby a pommel-nut screws into place. Inexpensive decorative knives and swords occasionally feature a hidden false
