Cliff,
I started off using a strong grip on the SH, but found it not to be the grip for me. I just wasn't getting the best performance. I therefore held it more loosely, and found that, due to the slim grip, that my hand moved around quite a lot during heavy (and I mean HEAVY) chopping. Full power swings. During this movement (and while this movement was a little unsafe, my hand never came close to coming off the handle due to the back and front guards. Very good design.), my pinky finger glanced quite a lot off the pommel. I found it a little uncomfortable, and I expect extended periods of heavy chopping with the SH could cause some rubbing/chaffing on my hand, especially the pinky. But, this is ONLY during heavy chopping, which in my opinion, is not the SH's true niche (atleast not its main niche). I find the thinner handle slabs uncomfortable to use during utility cutting, but that "uncomfortableness" is only because I dislike slim handles, and doesn't every come close to hurting or rubbing my hand.
