Looks great to me , you will save a lot of money making tools yourself.
As you use them you will fine tune the heights and angles untill they
work better for you than cookie cutter "storebought" tools .
As for handles , that is a personal preference, so whatever is comfortable to you works.
There's a satisfaction in using tools you made yourself, well done.
