First you are going to cut the golf ball in half; this is easier said then done, as cutting a round object can be very difficult. I would recommend first clamping the golf ball in a vice to secure it - then SLOWLY cut through the golf ball. If you cut too fast you will heat up the blade and either bend, or damage it. It is much easier to apply ONE continuous cut - rather than cutting part way through, turning the ball, and continuing the cutting. It is also helpful to note that you do not need to cut through the middle of the golf ball - you can just cut off a side portion as I did.
