X-ACTO Precision Razor Saw Set with 2 blades, for delicate sawing of models, balsa, plastic, metal and railroad track.
Hobby saws, often called razor saws, make straight controlled cuts that a knife cannot: removing resin casting blocks, separating control surfaces for repositioning, cutting sprue gates on thick parts, and slicing styrene strip and brass tube. For scale modelers doing conversions or working with resin kits, a fine saw is essential. Blades range from photo-etched ultra-thin sheets to traditional backed saws with rigid spines. When choosing, consider the kerf thickness, since thinner blades waste less material and leave cleaner mating faces, the teeth per inch for the materials you cut, blade stiffness, and whether the handle accepts multiple blade shapes. This guide covers saws for delicate detail cuts through to heavy resin work.
