Q: How do I cut my wax?
A Most people use a hammer and chisel to break hard slabs up into chunks. If you get a case of wax you can prop one end of a slab up on the side of the box, leaving the other end to lie inside on top of the other slabs - and give it a whack. This will keep the chunks of wax clean and contained You can also freeze it for a while and then drop it on the ground.
For softer container waxes you can use a knife to cut the slabs up into more managable hunks.
