I left my X27 there with the guys who had the tree removed. I guess the guy (60) told his son (29) that I did that piece is 6 minutes, so the kid's gotta try now. I guess he didn't feel like trying to lift one onto the splitter.
Anyway, I like the X27 also, but the GB keeps calling me back. The X27 is longer, and the extra length gets in the way a little bit when I choke up and make little swings. Also, and I've been meaning to play around with the grinder to see if I can fix this, but the Fiskars gets stuck on the cheeks too often in my opinion. It might not have been an issue here, but it happens enough to bug me. I'll split a piece just enough to separate it, but not enough to knock it away from the bigger piece. It doesn't always work perfectly like that, but sometimes, and the Fiskars will sink just enough that the almost barbed portion of the bit gets stuck and won't easily back out. Instead you have to hold the handle straight up and down and wiggle it side you side until it walks up and out.
Other than that, I like the Fiskars a lot. It really splits quite nicely, but because of the head design and the comfort of the GB handle I usually pick that one up and leave the Fiskars for people who want to take a stab at splitting the easy way.
