Dad bought me an x27 for Christmas (I asked for it mostly out of curiosity). I have to say that if I had known about this a year and a half ago when I bought my splitter I probably wouldn't have bought the splitter This thing works as great as everyone says it does! We cut 8 white oaks in the yard a couple of weeks ago and I have been processing as time allows and have done all of the splitting thus far by hand. This thing doesn't not beat me up or wear me out anywhere near like my 8 pound maul used to. What makes these work so good? Is it the sharpness? I've tried splitting wood with a regular axe and it just can't compare.
