If things look cropped after a rotation, use Image>Fit canvas to layers to enlarge the canvas to uncover the hidden parts.
If you draw around the knife create a new layer (with transparent background) and draw on it (as if you were using tracing paper). Then you can hide the original layer with the object and can print just the line drawing.
But I strongly suggest that you trace your lines using the path editor. The paths you create that way are just "virtual" lines (thin blue/red lines). To make the drawing from them: add a new (transparent) layer and Edit>Stroke path (use "Line" mode).
