When we see 2 but call 10?

I am the largest in my family of fifty.
The youngest of our family lives separately from the rest of the family and so do I.
I am regarded as harsh and tough.
I am so large, you cut me in two equal halves,

Who am I?

Since the town is quite small, there are only two barbers in the town � one on the North Street and one on the South Street.

While the barbershop at the South Street is pretty tidy and the barber as well has an impressive haircut.

Which barbershop will the tourist visit for his haircut and why?
