Seems to me a lot of that detail could be handled with a good texture.... otherwise, making those "fishscale" contours is going to involve perhaps extruding some shapes and patterns just slightly out of the basic handle shapes.

Same with those indents along the side. Either cut the grooves and extrude sections inward a row at a time... or consider doing it with shades on the texture.

I recommend you draw a poly of the plan outline (with the side ridges), extrude it and rotate the top surface to make the slope.

Then triangulate it and use the boolean plugin to cut out the space for the blade and the conical hole. Before using the boolean plugin, ensure that the surfaces are all facing outwards (press 'n' to check normals).

Use a cylinder with one end reduced to make the cone that cuts out the 'pencil tip' shape.

What Andy's describing there is the hardest thing for a newbie to learn: how to think in terms of the available tools and commands to arrive at the shape you want, and not getting so worked up about the shape itself.

Or, said another way, learning to "think in the program" you're using.

Keep at it, though, and don't be afraid to just start over with a fresh(er) approach. Sometimes that's the best way to learn.

Those graphic anamolies seem to indicate multiple faces very closely stacked on top of or parallel with each other. Perhaps the inside and outside of the glass?

The effect you are seeing is because of AC3D's transparency on a material.

AC3D offers only a preview of transparency. It does not sort surfaces/pixels into order before drawing (which would slow things down a lot).

Rendering using Povray or similar will give the correct results.
