Yes the blade saw teeth are functional to cut materials like wood or bone. The tool kit includes a small bimetal hacksaw blade to cut metal. There is also a fire steel that can sharpen blade and generate sparks to start a fire. There is a full length tang but the grip covers it on one side.
What can you say about O1 steel? It becomes rusty or polishing saves the blade?
Are you planning to use the knife or it will be only collectible item?

Tool steel will rust if not protected. I protect tool steel blades with a oil and wax coating. This method works keeps the blade free of rust. Tool steel will hold a sharp edge longer and is easier to sharpen then stainless steel. I am a collector of many things. I plan to use this knife for hunting. I live in USA. I use a Google Chrome translator to understand Russian text.
