I bought a gas log splitter about a year ago and have already split about 20 cords of wood with it. A couple of features that I am SUPER glad I got - but perhaps wouldn't have known about before I started using this one.
The "wings" are EXTREMELY useful. When you split a large diameter log, I let the far side "half " roll onto the wing. Then I finish up splitting the near side half one or two more times, tossing down the split pieces when I'm done. Then I reach over and bring the far side half into position and do the same. In short, the wings keep you from having to bend over and pick up split pieces. I wouldn't buy a splitter without wings!
The second "can't live without" feature and unbelievably absent on many models is an "auto-return" valve. This is a REAL time saver. When splitting, you of course have to hold the lever to bring the wedge into the log. However, when you are done, an "auto-return" will retract without you having to hold the lever. So, all of the time that you would save in having to stand there and hold the lever can be used to fetch the next log. This time savings may seem small but it really adds up.
Anyway, I purchased the champion attached below. It has both of these features and has simply been dead-nuts reliable and super-easy to start.
