I am considering purchasing an electric knife. The type with a set thermostat. Then I thought I should consider the electric plane. I have 5 hives and if I am lucky this year will have a total of 20 supers. Certainly 10 supers. What do you find to be the best method for a small hobby operation with about 5 hives? I was very impressed with the uncapping machine from Brushy Mountain for about $1,200, but my hobby is too small to justify the price.
