I love knives. That's it. 1 simple tool, 2 parts but so many fonctions. I had this idea while I was trying to find a scalpel for leatherworking and didnt succeed. So, as my first instructable, I will show you how to make yourself DIY heavy duty craft knives (or other cuting tool) of any shape you want and for less then a dollar. This way of making knives is called the the "stock removal method". Since we will be using knives to make knives, it's very simple and fast.
As you wll see in the pictures, yes, this is an instructable I made in the futur ;) Micheal J Fox helped a little but Doc Brown was 2 busy picking in the trash!
Step 1: Liste of Tools and Materials
-Marker or pencil
-Sandpaper (last pic I used 400grit)
-Hacksaw or handheld grinder
-Gloves and protective eye gear
-Sharpening system of your choice
-Old butter knives : I found mine at a thrift store for 0.25$ each. I would advise to take some of the same model and that aren't to thick. Thiker blades will be stronger but can make detailed work on some type of materials like foam or leather difficult.
-Plasti Dip/Paracord/Wood (FOR THE HANDLE) : Nice finishing touch, adds grip and prevents that anoying clinking sound. Can be found in most hardware stores or military surplus.
-Degreaser/WD-40 : To clean the metal if you plan on using Plasti Dip to cover your handle
Step 2: Preparation and Planning
Step 3: Shaping the Blade
Once the blade has no kinks you can start filing the cutting edge at a 30'angle. It is recommended that you flip the knife as often as you can so the sharp edge is centered and well balanced along the blade. Once you are satisfied with the blade, you can use a knife sharpener, a sharpening stone, sandpaper or strops to finish the job. I use strops, they do a great job IMO and are easy to use. An instructable has already been made on the subject but I will soon upload my own.
