Japanese 2‑Blade Marking Gauge (Mortise Gauge)

• Scribe Two Parallel Lines in One Stroke: Dual-blade design lets you mark two lines simultaneously for faster, consistent layout work. • Converts to Single-Line Use: Extend only one blade to use it as a standard marking gauge for single-line scribing. Note • Please check blade height alignment before first use. • If lines appear uneven, re-check blade projection and adjust by sharpening the higher blade.
