Below is a list from the article Scratchbuilding a Diorama (found in the FEATURES - HALL OF FAME article #9)., While this may appear somewhat out of context in terms of the comments, it is a nice basic listing, and why/how you may use the tools and supplies. Of course as a modeler you will NEVER be finished buying tools... either because you need to replace some that wear out, or you find something new that will do the job better than your old tool... or like me, you simply get hooked on trying out new modeling tools and gizmos. Hope this helps:
Razor Saw – for making longer cuts in plaster and wood
Xacto Knife (#11 blade) - for fine detail cutting – keep several new blades on hand!
Rotary Motor Tool – the most valuable tool in the studio
White Glue – or other “safe for Styrofoam” household glue
Glue Gel (Fabritac) – for joining irregular surfaces and multiple materials
Cyano-acrylic glue (“superglue”) – for fine detail work
Right Angle guide – to insure precision and consistancy in your measurements & cuts
Metal Ruler – to insure straight cuts on marks and lines
Sanding paper and blocks – to shape and smooth wood and plaster cuts
Craft Scissors – for cutting thin papers and trimming up in general
Marking pencils and felt-tip markers never an oil-based ink pen or ball point!
Fabric tape – number of uses, particularly in smooth out gaps and seams in plaster
Tissue paper – for creating “cloth textures” on a smooth surface
Interior wall spackle – great for filling in the cracks and seams in your buildings
Concrete patch paste –a wonderful scale substitute for “stucco” or mortar
Hobby paints – discussed in greater depth in the next section
Hobby brushes – ranging from 0/0 to 10/0, with some flat and angled edges too!
Alcohol or Turpenol thinner - to clean brushes and thin paint for washes and stains.
Breathing filter and goggles… the dust from some projects can be overwhelming at times!
Hobby Tweezers or Needle-nose Pliers – to handle some of the tiny parts while gluing
