Back-Lock Folding Knife

This back-lock folding knife references the structural design of the Cold Steel SRK (Survival Rescue Knife). The model requires zero supports during printing. Assembly needs no tools, adhesives, or hardware - components snap together through precision interlocking. Project Background:My ongoing research focuses on developing 3D-printable folding knife locking mechanisms that are simple, efficient, and durable.Key Design Requirements:The locking mechanism maintains natural state in both closed and locked positions without compression deformation - critical as 3D printed materials lose elasticity under sustained stress.No Z-axis force bearing capacity - compensates for weak interlayer adhesion in FDM printing.Print-optimized architecture with seamless integration for other 3D printed components, enabling support-free, hardware-free, and glue-free assembly.Development Status:This project represents a successful milestone achieving all specified criteria. Ongoing research will produce addi
