I'm a bit late to reply, sorry.Hard to tell from the picture but is the lapping tool split?
No, it's not necessary
I sharpened it to the angle of the needle and sharpened it with a file - making a place for the abrasive to stay - it's made of steel
I tried with aluminum, but it's too hard to do and it wears out too fast
