Knife Locket DIY, Karambit Knife

Make a stunning knife locket yourself with simple tools. This video will give you a detailed look into how to make a knife and all the process involved. #knifemaking #miniature #miniatureworld #diy #howtomake #karambit #karambitknife Knife Blade: - 1095 high carbon steel is used to make the knife. This steel is used since it responded very well to heat treatment. Drawing of the knife is stick on the top of 1mm thick 1095 steel and the profile is cut using jeweler saw.

A neodymium magnet is used to hold the knife blank while surface grinding. Sand paper (220 grit) is placed on a flat surface is used for surface grinding. Knife Beveling: - Beveling can be done using a jig or just by hand, here I am using a knife beveling jig. Beveling is first done using a file and then it is finished using sand paper. Heat Treatment and Hamon: - Hamon, literally "blade pattern" is a visual effect created on the blade by the hardening process. The hamon is the outline of the hardened zone (yakiba) which contains the cutting edge (ha). Blades made in this manner are known as differentially hardened, with a harder cutting edge as spine (mune) (for example: spine 40 HRC vs. edge 58 HRC). This difference in hardness results from clay being applied on the blade (tsuchioki) prior to the cooling process (quenching). Less or no clay allows the edge to cool faster, making it harder but more brittle, while more clay allows the center (hira) and spine to cool slower, thus retaining its resilience (Source: - Wikipedia) Hamon clay ingredients: - 2 part rock powder + 2 part clay + 2 part charcoal powder + 1 part rust Rock powder: - Ground fine sand, silt, or polishing stone powder provides a filler that will counteract the tendency of clay to shrink and crack as it dries. Clay: - The partially dried clay before pulverizing. Clay sticks the ingredients together and onto the blade. Charcoal: - Powdered charcoal being reduced to dust. Charcoal provides some micro pores as it burn out, allowing for some heat expansion and also affecting cooling time. More charcoal is added to the slip mixture than to the body clay mixture. Rust: - In this case, fine steel filings and powdered iron oxide provide some thermal mass and make up part of the non-shrinking filler material. The body and spine are coated in a thin layer of clay that will prevent the steel from cooling too quickly in these areas. A uniform thickness is important for even drying, heating, and cooling during various stages of yaki-ire. An almost runny but not watery mixture helps create a thin and even layer (think pancake batter not butter). When this layer is dry a very thin slip layer of clay that is higher in charcoal content is applied to the exposed edge, the charcoal burns out in the fire and the resulting porous clay surface has been found to cool steel faster than if it was bare. The clay slip also helps prevent oxidation and decarburization (loss of carbon at the surface) while in the fire.

When the temperature of the knife goes above recrystallization temperature it will become nonmagnetic. Once the knife reached required temperature it is heated for few more seconds and suddenly quenched using used engine oil. Polishing: - Surface of the knife is sanded using 220, 320,400, 600, 800, 1000, 1500 and 2000 grit sand paper in order. Then it is polished using polishing compound. Etching: - Knife is etched to being out the hamone. Dilute ferric chloride solution is used to etch the knife. After the etching it is polished again to remove the oxide layer created during the etching. Handle: - For handle we are using micarta for handle. Micarta is a brand name for composites of linen, canvas, paper, fiberglass, carbon fiber or other fabric in a thermosetting plastic. It was originally used in electrical and decorative applications. We are making our custom micarta using paper. White and black paper is alternated to create the pattern. Paper is soaked in polyester resin and cured under pressure in between to flat plates to create micata for knife handle scales. Knife handles are cut from the micarta sheet and holes are drilled. Handle is fixed to the blade using 5 min epoxy and two brass pins. Then the handle is shaped using sand paper and then polished. Masking tape is used to avoid scratching the knife. With some patience and skill you can sharpen the knife to razor sharp. Thanks for watching the video. Please like share and subscribe. If want any more information please put it in the comment.
