The HRLM has a larger handle - both taller and longer than the HC.
For me, the HC's handle is just a bit too small - whereas the HRLM's handle fits VERY nicely. The HRLM's handle is pretty much identical to the RMD's handle behind the ramp and guard. But, the ramps are different between the HRLM and RMD.
I have not yet tried, but I have often thought that if I were to grind the grip area at the index finger area forward into the guard about 0.25" or so and with a slightly tighter radius, I might be able to increas the handle length to be more suitable to my hands and my liking. I have fairly large hands though. Many might like the HC's handle as is (????).
Outside of the handle, the HC's design is GREAT!
As is, I wish for a bit longer handle. For me, the Vex is the "One" for smaller knives off the shelf. The Vex is not as sexy looking as the HC, but it is a very comfortable and functional design.
