It can be done with a box cutter or other similar razor sharp knife.
I've never done enough of it to gain any proficiency though, mine always just looked like a kid did it LOL.
If you're able to get it done, though, you might want to consider sewing a square of heavy canvas or something over the split in the middle to make sure it stays together like it's supposed to.
