🛠️ Recommended Tools and Materials for Assembly
To successfully finish and assemble your 440C Peanut Folding Knife, you will typically need the following items:

Essential Materials:

• Handle Scales: Choose your preferred material (e.g., custom wood, bone, G10, Micarta, or Acrylic).

• Pin/Rivet Material: 3/32 inch rod stock (brass, stainless steel, or nickel silver) to fit the pin holes.

• Adhesive: High-strength epoxy (like 2-part clear epoxy) for securing the scales to the liners/spacers (if included).

• Oil/Grease: A small amount of lubricant for the pivot and blades to ensure smooth operation.
Required Tools:

• Abrasives/Sandpaper: Various grits (starting around 150-220 grit up to 600-1000 grit) for sanding and shaping the handle scales and finishing the metal.

• Files or Belt Sander: Necessary for shaping and profiling the handle material to match the knife‘s frame.

• Drill Press or Hand Drill: Used to drill through the handle scale material to align with the pin holes.

• Hammers: A small ball-peen hammer or riveting hammer for peening the 3/32 inch pin material.

• Clamps: Small C-clamps or vise grips to hold the pieces securely during the epoxying and assembly process.

• Metal Polish/Compound: For achieving a final shine on the 440C stainless steel blades and components.
