This is a very decent first render…!
Since you ask for critics, i’ll give some, so you can learn =)
First: The handle could use some subsurf and “set smooth”. Not everybody agree on using subsurf, but imo it’s a great tool, unless you are going for lowpoly modeling. For subsurfacing, hit Add modifier > subsurf under the editing menu (F9) the numbers decides how many times to divide your mesh. the “levels” is in editing mode, and the “render levels” is when you render.
Next hit the “set smooth” button in links and materials, also located in the editing menu (F9, again).
Next, you could use some reflection on the metal, and maybe another material for the handle. The reflections is put on this way: shading menu (F5), hit the “mirror transp” part. turn on the “ray mirror” button, and turn op the RayMir slider.
For more on texturing, and materials - try looking in some tutorials - that is by far the easiest way to learn, and there are hundreds of them all around the internet. (here is an overview of some of them: http://www.blender3d.com/cms/Tutorials.243.0.html
Hope it’s usable information, and welcome to the Blender society =)
