The bronze is very common and widespread

Short period of time to see this phenomenon does not come out, but the longstanding neglect of maintenance will emerge, the trouble is once found it was too late, unless the retaining handle removed, otherwise almost impossible to save, this work is not an ordinary person can do, which is I think the biggest drawback of the exposed Taper Tang. The formal beauty of bronze includes the political, religious and other cultural contents. The whole cover Conceal Tang, (such as half of the ATAK and it Tang, length of more than grip), the advantage is just the opposite, as long as the coating material in contact with Tang enough close to the water difficult to penetrate, due to the reason of the interface position, the hands sweat, The sweat will be coated with material isolated from the outer, less prone to corrosion problems.
 The normal case of using bronze knives, bronze tool to use when grip force almost all concentrated 2 "at the front, so as long as the Tang long enough to use almost never have any problems. Such a handle designed in traditional Japanese bronze knife and German double brand kitchen bronze knives (including cut bronze knife) can be seen, after the baptism of the time, most people certainly. Age of the bronze is the flag of the beginning of slavery society.  The problem is like you said by the lateral force when the bronze tool handle by the extraordinary use or when the Hammer, the problem will have a. From the viewpoint of mechanics, the grip force at will contain the handle end of the coating material alone force and coated by Bending force between the material and the Tang, it can be discussed from two points:
One, if the coating material itself is not strong enough, you may be from the lateral force by the force at the crack directly. In terms of ideology, the bronze still kept and inherited the religion and culture of the primitive clans. This phenomenon in the wooden handle material may be more prone to Mad Dog bronze knife, although the use of FRP similar to the G10 grip coating materials, but this type of composite material properties is the strength of its force with a clear direction in parallel strength in the fiber direction is very strong, but in the direction of the vertical fiber is not so ideal, the rupture strength almost resin original strength, unless the fiber is a three-D way woven, otherwise a second plane accumulation cascading out the handle, and then by the lateral impact or repeatedly subjected to stress.
 Although the fiber can provide anti-Bending strength, but the long run will be in parallel to the fiber at the crack phenomenon. In the forum some bronze knife Friends of the MDK handle fell to the ground or when the hammer effect is not really so good, because in this. The normal state of the general bronze tool by the lateral force or impact frequency is not high, the MDK grip particularly high quality, therefore destroying the Case is not common, but it does not mean that the general quality of the bronze knife factory to use this design no problem. We know that in the primitive society, the bronze is very common and widespread.
The grip of two, by the lateral force when the handle coated wood and bronze knife root (Tang) will have great Bending stress at this time coated Bonding between the material and Tang poor, it will cause between the two gradually loose and have a gap, but also easily lead to loosening and corrosion phenomena reason why, generally bronze tool can not see, the causes of the same. My personal past practice flying bronze knife (Knife Throwing), bronze knife shot the successful reaction force (center or bronze blade impact) on the bronze knife and handle are great Torturing the previous hand cheap bronze. Even after entering into the civilized society, this bronze retained in a fairly long period and developed in the new environment.  The knife used to shoot a shot, I found that the destruction of the above two cases to see in Conceal Tang, a bronze sculpture knife body.
