There
are many makers who might use a "Palm Swell" for a right or left handed person. For my $.02, that would mean the thicker, smoother side in my palm...and the thinner, gnarlier (particularly stag or bone) side gripped by my fingers.
But, sometimes I'd like to see closely matching handles, in color, size, and figuring, especially in wood
However, if a knife looks good to me, and feels good in MY hand, I'm happy...

...well, most of the time.
