Key Features

1. High-Carbon Steel Blade

The FZ21503-G uses a high-carbon steel blade designed for everyday cutting applications.

High-carbon steel is commonly used for cutting tools because it can provide a sharp cutting edge when properly maintained.

The exact long-term edge retention will depend on the material being cut, frequency of use and storage conditions.

2. 30° Sharpening Angle

The blade is listed with a 30-degree sharpening angle.

This specification is designed around a practical cutting edge for the product’s intended stationery and household applications.

3. Aluminum Alloy Metal Body

Detailed product listings describe the body as a high-quality aluminum alloy with rounded edges and a matte finish.

The metal construction gives the compact tool a more substantial feel while the rounded exterior helps make it comfortable to hold during suitable everyday tasks.

4. Compact 145mm Design

The FZ21503-G has an overall listed length of approximately 145mm.

Its compact dimensions make it convenient for storage in:

• Desk drawers
• Stationery organizers
• Office bags
• Home storage boxes
• Tool organizers

The 145mm specification is reported by multiple product listings.

5. Push-to-Lock Blade Mechanism

The utility knife incorporates a press-operated locking and unlocking mechanism.

Listings describe the blade as locking and unlocking through the pressing mechanism, helping provide controlled operation during intended use.

6. Rounded Edges

The metal body features rounded exterior edges rather than an entirely sharp-edged housing.

This contributes to a compact and comfortable handheld design for routine stationery tasks.

7. Matte Finish

The aluminum-alloy body is described with a matte finish, giving the utility knife a clean and understated appearance.

8. Compact & Portable

The small form factor makes the FZ21503-G easy to store and carry for appropriate home, office and stationery applications.

It is particularly useful when you want a dedicated cutting tool without carrying a larger utility knife.
