I live in the NW corner of the Arkansas Ozarks. This is the home of American hardwood. Most of the oak railroad ties that helped build the US railroads after the Civil War came out of this area. We have lots of white oak, red oak, ash, hickory and elm. This wood can be a real b_tch to spilt, especially below a crotch or a piece that has a lot of old branches in the grain. The elm can be next to impossible, if you have a gnarly piece. I've been using a Fiskars with lots of success, but if I get a really gnarly piece of elm or other twisted grain wood, it's almost impossible to split. I just took delivery last night on a Big Ox splitting maul. My buddy who has cleared a site to build a home gave me the equivalent of 2-3 cords of wood from his site. I've split most of the 18" logs with my Fiskars splitting axe, but needed something for the big bad stuff and the Ox just wasn't able to split it. After bragging about my new $120. splitting maul, I attempted to split a piece of elm that the Fiskars and my 8 lb maul had laughed at. I gave a mighty swing of this 6.6 lb German splitting maul and much to my chagrin, the maul bounced straight up int he air 3 times. I tried it again and finally got to split around the edges of the 24" round, but the center with two whorls of grain resisted everything I attempted. So, I'm not sending back the Big Ox and am going to give the GB splitting maul a try and hope it does the job. I heat the whole house with hardwood.
