Saw-Piercing Pattern Generator
Printable Islamic geometric saw-piercing templates for pendants and ornaments. All patterns are structurally validated — every bridge meets minimum width, every cut-out is wide enough to thread a saw blade through.

Tips
- Use rubber cement (not white glue) to attach the template — it peels off cleanly after sawing and won't gum up your blade.
- Drill your blade-threading holes before cutting any interior shapes. A #2/0 drill bit works for most patterns.
- Support your metal on a bench pin and keep the saw blade perpendicular to the metal surface. Let the blade do the work — don't force it.
- For intricate patterns, use a finer blade (4/0 or 6/0). For thicker metal or simpler patterns, a 2/0 blade cuts faster.
- After sawing, clean up edges with needle files and finish with progressively finer sandpaper (400 → 600 → 1000 grit).
How It Works
This tool builds patterns using the polygon-rosette construction method — the same mathematical approach used to design traditional Moroccan and Persian Islamic geometric ornament. A hexagonal tiling fills the design area; at each tiling vertex, a 6-point star is constructed, and interlace bands connect adjacent stars into a continuous, mathematically precise weave.
Every pattern is checked against structural constraints derived from the metal gauge you select: minimum bridge widths between cut-outs, minimum cut-out dimensions large enough to drill a blade-threading hole and navigate a jeweler's saw blade through, and a solid border frame that holds the pattern together. The star-size slider controls how big each star is — small stars produce fine, intricate work suited to 4/0 or 6/0 saw blades; large stars make bolder pendants with more visual weight. The band-width slider sets the metal thickness between cut-outs, and the centering selector chooses which symmetry point sits at the center of the outline.
