Fast Easy and affordable. Roll over your capped comb and let the spikes break open each cell so that the honey can be extracted. You will be able to roll through your frames in no time. Roller is 4" wide and can be used on Shallow, Medium or Deep Frames.
This is the best uncapping device Ive ever used. I estimate it is 4 times as fast as a knife and it is easier to get into the cells that are below the general plane of the frame. The only downside I can imagine is that you give all that capping wax back to the bees.
