For many years I carried the orange plastic trowel when back packing. Even with the handle drilled out to reduce weight it still weighed 45g.
Needless to say it finally broke at the handle.
Looking at the junk (saved treasures) in the shed for a replacement I noticed I had some Aluminium Capping (approx 0.5mm thick) and an old garden trowel. These started my thinking and resulted in The T Leaf.
The final weigh in resulted in a larger trowel that was only 39g.
Tools I used :-
A sheet of paper salvaged from the printer.
Angle grinder with a metal cut off blade.
An electric drill or a hand drill.
A 15mm metal drill bit.
A range of silicon oxide sanding papers.
Practice safe work.
Use ear muffs and safety goggles. Hold material in a vice or clamps when drilling or grinding.
Step 1: The T Leaf : Design and lay out
Length 170 mm.
Widest point 90 mm.
Rounding down to approx 60mm near the point.
The fold in the capping strip was used to add rijidity.
Fold the paper in half-lengthwise. Using the dimensions above layout your overall shape. Remember that the final template will be symmetrical along the fold.
Cut along your curve.
