For what it's worth, I'm kinda down on the commercially available pumpkin carving tools. The handles are too small for adult hands, and the blades, etc. tend to be pretty weak too, (and the battery powered saws look ridiculous). At this point, I use real tools from the hardware store for the basic stuff, and sculpting tools from art shops for the detail work.
