I concur with Poncho😉
A food scale will do the job.
I have one, but no interest in taking apart any on my tools.
You can minimize weight, not certain you can maximize strength.
I find the REBAR is the best awl around MT at the best value for my needs. A Older PST is the minimum.
A titanium built tool way be the lightest, yet the cost will be ridiculous I would imagine.
Best wishes.
