Our New model K-1 knife which designed by Solo Jack finally came out. We would like to share the details about this model here with you. Specification: Ceramic ball bearing system Blade Length : 3.8” Blade Thickness:0.157" Overall Length:8.8’’ Blade Material: RWL34 (Made by Damasteel company) Hardness：60-61HRC Handle Material:6AL4V Titanium Inlay Material : Marble Carbon Fiber/ Carbon Fiber Weight:4.93 oz Locking:Frame Lock We always aim to make more and more high quality knives as well as try new things. This is our first time to use RWL34 which made by Damasteel Company on our knives. Martensitic stainless powder steel RWL 34 which Rapid Solidified Powder (RPS) based steel is a variation of the 420 martensitic stainless steel with >13% Chromium. The addition of Molybdenum and Vanadium gives the RWL 34 even greater corrosion resistance, hardness and strength. Close equivalent to 154CM. Characteristics of RWL34: -High edge strength -High hardness after hardening and tempering -High corrosion resistance -Easy grinding and polishing -High purity and cleanliness Hopefully those information could help you undersatnd the RWL34 steel. Here are some photos of K-1. 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 knives, 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 passing the hardness standard test but still easily get worn in actual use. Reate Knives are using 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. Therefore, the sharpness and durability of the blade are assured. This helps bring the performance of the material to the best. Thank you very much for your time. Reate Knives Team.
