剣先

1. Origins, structure, and basic meaning

• Structure: 剣先 is read as けんさき and is a noun for the pointed end of a sword or blade, not the whole weapon.
• Basic usage: Use 剣先が床に触れる for the tip touching something and 剣先の傷 for damage located at the point.

2. Common pitfalls and similar expressions

• Part versus whole
  • The whole sword is being carried, but 剣先 identifies the particular part kept off the floor.
• Location of damage
  • The artisan works on a small nick at the blade tip rather than damage across the entire blade.
