The main things I noticed in use from this day:
I rarely use gloves, and was glad to not develop any hot spots. I work with a leveling hammer every day, so that helps, but was a little worried. Needlessly, it turns out, a testament to all the makers.
The GSO-10 is a beast. There's just no two ways around it. It has great geometry and bites very deep. And although I haven't checked actual weights, feels no heavier than my M9 in use. The one critique I have on the 10 is that when I was really getting into it and using all the force I could muster, the protrusion toward the butt of the handle was uncomfortable against my small finger. If I had used a lanyard to lock my hand in, I could have possibly mitigated that occurrence. Still, I'm very impressed with it's performance, a real winner, and will definitely try to snag one of the new model 10s to try out as well.
If my main focus was batoning, I would grab the SRKW M9. The geometry of the M9 is just superior in the splitting department, whereas the GSO 10 is superior on the chopping side of things. Although slim, the M9 handle just works wonderfully for me. But that is highly subjective and will not be the same for everyone. This was the M9 CG which is saber-ground and did not bite as deep as the 10.
G L Drew's blade, what a sweet user. It was outmatched here, however, that did not remove the smile from my face while I was using it. It is very well balanced and carries much 'smaller' than its actual size. It will be a pleasure to pack, or to do chores around camp. Also, the G L Drew and the GSO-10 were much better at snap-cutting the few light limbs and twigs that I removed before starting into the log. I'm sure this is a tribute to their geometry, and the M9 came in last in this department with its thicker grind. One critique on the Drew, it could use a longer guarded area between the index finger and the blade, and the handle may have a bit too much taper, forcing the hand forward, but now I'm just getting picky
There are probably better tests for a chopper, but for just some fun experience this worked out pretty well. I was pleased with how everything performed, and can say for sure that a GSO-12 would not have been overkill on this one!
Cheers!
