The Axis Lock on the Grip is slightly easier to use than the ball lock on the D'Allara.
Blade deployment on both knives is butter smooth. I probably slightly favor the Grip due to it's thumbstud feature and it's location in relation to the hand when gripping the knife to open the blade. It's just second nature to operate this knife. Purely preference but, I slightly favor it over the hole in the D'Allara. Still, this is a close call. That 14mm hole in the D'Allara is awefully nice.
Blades are mostly a draw but, in some ways I had a slight preference for the Grip blade. However, I need to qualify this statement because I have the Ritter RSK version. It's blade is slightly different than the mainstream Grip and, is made from S30 steel.
The D'Allara handle is slightly more comfortable in the hand. Actualy, quite a bit more comfortable. But, that doesn't mean the Grip is uncomfortable because it's not. In fact I thought it was an easy knife to hold and use. But I give the advantage to the D'Allara on this one. It is extremely comfortable to hold. If you need to hold a knife for significant periods of time, the D'Allara would be my choice between these two knives because other features are so close.
I like the pocket clip on the D'Allara slightly better than the mainstream clip on the Grip.
Which do I prefer after all is summed up? Probably the Grip (Ritter RSK version) today. Ask me tomorrow and it might well be the D'Allara. Both are relatively inexpensive knives and, my recommendation is to get the Ritter Grip now and, the D'Allara later. Or, get the D'Allara now and, the Grip later. The D'Allara is less expensive than the Ritter RSK.
