This line cutter is 3D printed from carbon fiber reinforced PETG (PETG-CF), making it tough and durable for regular use. It includes a sheath that holds the cutter securely and protects the blade.

The ceramic blade stays sharp much longer than stainless steel and won’t rust. Ideal for divers, sailors or general outdoor use. I made this because I was frustrated with steel cutters dulling too fast and rusting.

The cutter comes in two versions:

• Single-sided blade: safer since the blade is exposed only on one side.
• Double-sided blade: lets you use the other edge if one side gets damaged.

Features:

• Replaceable ceramic blade that stays sharp and won't rust.
• Custom sheath for safe and secure blade storage.
• 316 stainless steel screws for best corrosion resistance.
• 3D printed parts using carbon fiber reinforced PETG (PETG-CF) for strength and durability.

Notes:

• Each unit is manually assembled and tested.
• Most wear happens at the blade tip. You can flip the blade around to extend blade life.
• Ceramic blades are sharp but brittle. Avoid cutting hard materials to prevent chipping.
