Product Overview
Achieve the Perfect Fit: Nattools Curved End Strap Cutter Independently Designed Since 2015
Elevate your watch strap crafting with the Nattools Curved End Cutter. This specialized machine is engineered to solve one of the most challenging aspects of strap making: creating a perfect, consistent arc for “curved lug” or “fitted” watch straps.
Designed as a core component of the NT32 Strap Making System, this tool allows you to effortlessly cut precise arcs for strap reinforcements (middle layers) and bottom linings. It ensures that your straps sit flush against the watch case, accommodating curved spring bars for a high-end, gap-free finish.
Key Features

- Reversible Cutting Pad: The base pad can be flipped for extended use.

⚠️ Usage & Important Notes (Please Read)
To ensure the best results and longevity of your tool, please observe the following:
- Shipping Adjustments: The fastening screws may loosen or shift slightly due to vibration during transport. Please inspect and adjust the alignment before your first use.
- Test Cut First: Before cutting your leather, please perform a test cut on a piece of cardboard or stiff paper to verify the size and alignment meet your standards.
- Primary Use: This tool is mainly designed for cutting the strap reinforcement (filler) and lining leather. It is not intended for cutting through thick, fully finished straps in one go.
- Maintenance: If the sliding mechanism feels stiff or has resistance, apply a small amount of lubricating oil to the guide pillars.
- Left-Handed Version: All Nattools instruments can be customized for left-handed users. Please contact us immediately after ordering if you require a left-handed version.
- Spare Parts: The cutting pad is consumable and reversible. Replacements can be purchased separately.
