Artisan Argentinian knife maker. How to make a steel knife, step by step.

We will start with the procedure for making a handmade knife We will use virgin 51-60 steel It is a steel more commonly used for cutlery This 51-60 steel can also be used recycled It is used for the elastic bands of vehicles José Miranda de Coronel Suárez who is a knife maker and he has guided me a lot and continues to guide me It's a technique that this craftsman José Vargallo taught me I use high-temperature paint Now let's move on to the clamp we'll grab it there and start cutting with the grinder all around Okay we've got it here and now we're going to move on to the belt sander to smooth out the entire edge and make it neat I use it to manage backups We are going to mark the center of what will be the edge to have a reference We will mark the handle where the rivets will go Old palette handles we recycle them cut the small pieces and use them for the rivet All this procedure must be done by drilling before tempering because if not once the blade is tempered It's already quite difficult to drill a hole in hardened steel To make a flat bevel I use a trigonometric grinder The widest part is 37-78 I put on the mask in case there's a lot of steel dust in the air Old blacksmiths always say that when you quench a blade and it takes on a medium white color it's because it has gained good hardness This is the cooking oil I order it at the butcher's And that's when they take out the oil drums that they throw away Well that's the oil I'm using Okay now let's find a file and give it a light sanding to clean the blade a bit so we can see the color of the weld Well thermal treatment is ready I don't know if you can see a yellowish color there It depends on how you see yourself now sometimes it's visible sometimes it's not But anyway thermal treatment is complete And now we have to continue working the sheet clean it well polish it a bit more It has a nice sound more or less Well with a blade we'll roughly mark my letter Now what we're going to do is refine this part of the front That is what we won't be able to fix once the end is attached That's why I use cardboard because if I don't when I tighten the vise If I tighten the grip it's not pressing the handles against the blade's tang Okay now we're going to sand this area on the frame Let's start with 80-grit sandpaper You can now wipe it and polish it I sanded it up to 600 grit I use 600 grain and then go to the cloth and take the lines The next step is to etch the mark onto the sheet which we do by electrolysis Now we are going to see it
