Apple Corer for making holes in foundation
An apple corer is a domestic kitchen tool that can be modified in order to make a tool for cutting holes in beeswax foundation, to achieve faster drawing of comb by the bees and save wax. 
This tool can be found in most households being used for its correct purpose, but if it has its teeth sharpened with a fine toothed file, it will easily cut holes in fresh foundation.
Sharpening the teeth on the inside of the tube, in the fashion indicated will also enable it to perform its original function more swiftly and with a cleaner cut. ?? ? ?? ?Apple Corer tooth sharpening
Why poke holes in new foundation? Is the indignant question that often follows my statement, but it is good for various reasons and actually speeds up the process of comb drawing by allowing the bees to communicate during the early stages, when normally they would be separated by a solid wall of foundation.
The holes allow the clustering bees to communicate with one another which gives them a more stable sense of community (my surmise, backed by observation), it also allows easy passage at several points for bees to traverse from one side of the growing comb to the other.
