I kept seeing reports on the x25 but couldn't see me buying such a short tool. X27 came out and I bought inthe same year. What a tool! First coupld splits and I said "this cannot be doing what I am seeing" Been using it on 8-12 cords/yr ever sincemostly black locust - fairlyi easy splitting and willow.
I have a splitter but it only sees the rejects (knots/forks, etc) from the manual splitting sessions. That splitting and stacking is what keeps me going, coming up on 81 and try to put in at least an hour a day when weather permits. Just finished a few hours ago the pile of willow rounds from last years harvest - going tomorrow to the wood patch to clean up the spots where I burned brush piles dueing the winter.
