...wow, this is even more impressive that you did this with a hand saw!
I was expecting some crazy expensive plastic only table saw blade or something.
well this is good then for the mod I want to attemp
Actually it's quite logical.
If one is skilled and can handle hand tools properly it is way better to use those than any machine.
The reason is: You can take it as slow as you like, meditate over every stroke if you want or need to, influence the speed of advance, precision or error rate.
The machine tools on the other hand have a defined speed - and the output quality is generated by the input you apllied beforehand. Once you've started the outcome is set - either good or bad.
In most cases machinery is just suited for steady outcome over several products or a high cut rate.
You'ld have to spend a serious amount of time to set machinery up to give a precise outcome, in most cases need a second specimen to test your setup. And still you wouldn't have the options of freehand work - that would require a silly amount of money spend in machinery.
