Rather than editing the mesh, it would be easier to make the bow transparent. In the Material Room, select the "Bow" material, set the Defuse_Value and Specular_Value to zero. Set the Transparency_Value to 1.0, and Transparency_Falloff to 0.0. This will make the bow invisible in the rendered image.

If you also want it invisible in preview, in your Render Settings, Preview tab, set "Transparency Display" to "Actual".
