Hello, bignickj69:

The square point will give you more precision around the earlobes and other spots requiring it. The square point is in essence a spike point with the sharp tip rounded out to take the bite out of it.

If you have a round point already, I think it's a good idea to add a square point to your lineup. For newcomers, I suggest staying away from the spike. I have several square points and love them. Next to barber's notch, the square point is my favorite.

Regards,
