Collapsible Axe with Spring-Lock Mechanism

This is a folding axe with a locking mechanism. It can be quickly deployed and locked. Simple to print with minimal supports required. No hardware needed for assembly. Adhesive is optional (single-color monolithic handle requires no adhesive; multi-color handles require adhesive to bond the decorative panels).

Two design options are available:

Integrated Handle & Decorative Panel Version – Simplified installation with a single-unit structure;
Separate Handle & Decorative Panel Version – Allows multi-color filament combinations for enhanced visual aesthetics, but requires adhesive bonding during assembly (handles to decorative panels)

Assembly Steps:

1. Bond decorative panels to handles. Skip this step if using the integrated version.

2.Install the hook assembly.

• A 0.2mm-thick sacrificial layer is designed here to avoid support structures. Pierce through this layer during installation.

3.Position internal components as illustrated.

Secure both handles,

• Place the axe blade,

• Fix the upper and lower ends with two locating pins.

The strength of 3D-printed knives cannot be guaranteed and they are suitable only for light-duty tasks, such as cutting paper or opening Amazon packages. Unless otherwise specified, all of my knife designs are intended for light-duty use only.
