I eat an ounce of dark chocolate a day. It is costing me $3 to $3.5 for a 3.5 ounce bar of my favorite. Last week I bought a block of Belgium made semi sweet chocolate (Callebaut) for $7.99 per pound, a much better price. But breaking it into one ounce pieces is very difficult. What if I purchase a coping saw with a fine blade to cut it. Seems that would work very well.
