Well my electric 5 ton splitter that we'd been using for nearly 20 years started acting up and not splitting as well as it had before. I decided to get another splitter. Not wanting to drop several hundred on a gas powered beasty I decided to go manual .. and not with a maul nor wedges and sledges. I decided to get a hydraulic jack style. I'm going to say the 10 ton rating is a bit optimistic but it splits oak and mulberry pretty well. Box elder and poplar are super easy. It's 18 x 8 inch size rated but I'm splitting bigger hickory but having to nibble off slabs before it will be able to split in half. Maybe 11-12 inch max diameter with straight grained wood. It's definitely not fast. Took me nearly 2 hours to split a face cord of mixed wood (oak, mulberry, hickory and box elder). But didn't use any fuel / electricity. Fitbit said I burned 500 calories hauling and then splitting for 45 minutes of cardio.
