Thanks for that! Now can you tell me why you're holding each knife with your thumb so far back?? That groove along the spine is for your thenar muscle group, and the swell goes in the pocket between the thenar and hypothenar groups. You are holding each knife like you're throwing a fast-ball, putting all the stress on your fingers, rather than letting it rest comfortably in the pocket of your hand (as in my pics above).

Here is a quick video I made a while back about handle-designs, shows the HRLM (same handle as RMD) toward the end:
