The Ontario PFC01 Button Lock Pocket Knife is designed for reliable everyday carry with a focus on controlled deployment and durable construction. Measuring 4.5 inches closed, it features a 3.25 inch stainless steel blade with a stonewash finish that helps reduce visible wear during extended use. The blade is deployed using a thumb stud and supported by an extended tang, allowing smooth, controlled opening for efficient task execution. A button lock mechanism secures the blade during use, providing stability and ease of disengagement when closing.

The handle is constructed from OD green G10 to deliver a secure, textured grip in varied conditions while maintaining structural durability. A pocket clip supports consistent carry and quick access, while an integrated lanyard hole provides additional retention options. The overall design balances cutting performance, handling control, and portability, making it suitable for utility cutting tasks in both daily use and outdoor environments.
