District 9-Plus were came out a few days ago.Compare with D-9A&B,District 9-Plus was totally improved. District 9-Plus combined with the style of A and B but the work is more sophisticated. And it is also lighter than before which is only 180g now.So with the weihgt loss, the blade around the center of gravity is more harmonious.What's more, process is more delicate as well as has two different color for the blade which are light and dark.
Reate Knives would like to talk a little bit about one important techniqueFreeze Edging Skill
As the final process for a blade, edging has a great effect on the performance of the knife, after all, the edge part is the main function area when using a knife. Normally, edging is operated on a high-speed running grinding wheel or grinding belt, which produces a very high temperature. Without a cooling system, the temperature on the edge goes up instantly to hundreds of centigrade, when it gets worse, it will burn and leave heat marks on the blade. Tempering or even annealing will happen on area of the edge where the temperature increasing instantly. It will harm the hardness and durability of the blade. Thats why some knives pass the hardness standard test but easily get worn in actual use.
Reate Knives use the freeze edging technique. During grinding, the temperature on the edge is controlled in a certain level of degree, which helps keep the hardness after the heat treating. Therefor, the sharpness and durability of the blade are assured. This helps bring the performance of the material to the best.
