That's a great job, Franco! I took a different approach and made a few folders out of cut-down back-pull razor saw blades that fold into a wooden handle with a wing-nut as tightener and pivot. Tried different thicknesses. Japanese cabinetry saws are the lightest (1 oz complete) but require careful use. Pruning saws are durable (2.5 oz, complete) as all get-out but hard to cut down. Sorry, no pix. The 4" pruning saw version will cut thicker stuff than I imagine ever needing.
