Considerations & Trade-offs

  • This is the Small version, so it is limited to sight beads between 0.050" and 0.125" in diameter.
  • The tool is designed specifically for installing sight beads; it is not a general-purpose screwdriver or multi-tool.
  • The handle is plastic, which keeps the tool light and simple, but may feel less substantial than metal-handled alternatives.
  • The spring steel collet is intended to hold the sight bead delicately, so the focus is on controlled installation rather than aggressive clamping.
