How to Make: PSYCHO TOMAHAWK (UPGRADED Wasteland Tomahawk)

About this video

ZNA builds a miniature tomahawk featuring a circular saw blade as the cutting head, using salvaged steel stock and a hickory handle. The project involves cutting and fitting the blade into a steel head, fabricating mounting brackets through bending and riveting, and assembling everything with hand tools. Along the way, ZNA confronts limitations with welding and pivots to traditional riveting methods, demonstrating how recognizing when to change course is part of practical problem-solving.

Key takeaways

• Knowing your tools matters—ZNA abandons welding mid-project and switches to proven riveting techniques rather than forcing a skill that isn’t yet reliable
• Iteration and discomfort drive improvement; ZNA acknowledges the struggle with welding but frames it as necessary practice toward mastery, not failure
• Salvage and repurposing materials reduce waste and cost—using leftover steel from previous builds keeps the project economical
• Mechanical fastening (riveting, bolting) is versatile and forgiving compared to welding, offering a reliable fallback for joining structural components
