I welcome fans to craft, today we will consider how to make a quality knife for a chef. For the manufacture of the blade, the author used high-quality carbon steel, the knife turned out so sharp that it easily cuts paper into thin flat sheets. The handle is made of wood, in front of it there are beautiful brass inserts fixed with brass rivets. The knife looks great, it is strong, sharp and reliable, such a product will be appreciated by any cook. If the project interests you, I propose to study it in more detail!
Materials and tools used by the author:
Material List:
- carbon steel for the blade;
- a tree with a beautiful texture (for overlays);
- brass or bronze for bolster;
- brass rods;
- epoxy adhesive;
- oil for wood.
Tool List:
- belt grinding machine;
- drilling machine;
- milling machine;
- a furnace for hardening the blade;
- sandpaper;
- a hammer, files and more.
Manufacturing process homemade:
Step one. Cut the knife profile
First of all, we will prepare the workpiece, we will need a steel plate of suitable length and thickness. Grind and level the plate if necessary. Next, draw a knife profile on the plate, if you have a problem with this, you can download the finished template from the Internet and print it on a printer.
First of all, you can drill all the necessary holes for the pins and rivets, the author uses a drilling machine.
Well, then we cut the profile of the knife, it can be cut on a tape cutting machine, grinder and other tools. The author grinds off excess metal using a belt sander. We do not need to sharpen the blade yet, since we still need to harden steel.
Step Two Quenching
The blade must be tempered so that the blade holds the sharpening. Each steel grade is quenched under different conditions, the quenching medium is also selected depending on the steel grade, most often it is oil. Correctly hardened steel will ring and spring, such a blade will not break, and the blade will keep sharpening for a long time.
Step Three Slopes
We proceed to the formation of descents, they at the knife for the cook should be as wide as possible. Such a blade will be thin and the knife will cut very well. It is important to know that it is necessary to grind hardened steel so that it does not overheat, otherwise steel tempering will occur. The author forms descents by eye using a belt sander, and so that the steel does not overheat, we wet it in water. As a result, we get an excellent knife, it remains only to make the handle.
Step Four Bolster
As conceived by the author, there is a bolster in the front of the handle; it consists of two brass plates. We cut out the details, give them the desired shape and drill holes. We will fasten the brass plates with rivets, the role of which is suitable for brass rods. We cut the rods to the desired length, hammer and rivet with a hammer. That’s all, the bolster is in place.
Step Five Handle assembly
We cut two pads of beautiful wood, one of them is immediately glued to the handle of the knife with epoxy glue. To glue well, we clean the metal surface with sandpaper. We wait until the glue dries and drill holes in the first pad under the pins.
Then the second plate is glued, again we wait for the glue to dry and drill holes. In the end, it remains only to glue the pins.
Step Six Final touches
When the glue dries, carefully grind the handle, give it the desired profile. This is followed by fine processing with fine sandpaper to a perfectly smooth state. That's all, the knife is almost ready, soak the tree with oil or epoxy glue so that the wood is not afraid of water.
The author sharpened the knife to the state of the blade, usually for such sharpening use small machines with grindstones of different grain sizes. The knife easily cuts paper, the homemade look looks great too. On this project is over, I hope you liked the homemade. Good luck and creative inspiration, if you decide to repeat this. Do not forget to share your ideas and homemade things with us!
