Assuming you would like tips on how to draw a knife:
When drawing a knife, it is important to first understand the different parts of the knife and how they work together. The blade, handle, guard, and pommel are the four main parts of a typical knife. The blade is the sharpened edge of the knife that does the cutting, while the handle provides a comfortable grip for your hand. The guard protects your fingers from slipping onto the blade while cutting, and the pommel helps balance the knife in your hand.
To begin drawing your knife, start with the outline of the blade. Then add in the details of the handle, guard, and pommel. Be sure to make each part proportional to one another—the blade should be longer than the handle, for example. Once you have all of your lines in place, darken them with pencil or ink to finish your drawing.
With a little practice, you’ll be able to draw realistic knives that look just like they could do some serious damage!
