Cool pics! Great focus. To think mine once looked so smooth and unblemished... That first picture really draws my eye to the sharp point of the rear edge of the blade.
If you'd like some creative criticism, read on. Otherwise feel free to ignore me.
I like the second picture better, because you get to see more of the knife and it looks grreat standing up like it is. But I don't like the color of the desk/table it's standing on. If you had something lightish colored, but matte finish to put the knife on for this shot, it might draw more attention to the knife iteself. Also, maybe take two more shots with this setup: one with the focus on curve of the blade with a large aperture for a nice blurring of the rear of the knife, and another shot with a small aperture and longer exposure to get it all in focus.
Is that a lanyard on the end of the knife I see in the second shot? Might be cool to wrap that around and try getting it in that last small aperture shot!
