HRLM is 9" overall, 4.5" blade. 3/16th, IIRC
RMD is 10.25 overall, 5" blade. Also 3/16ths I believe.
And I want to say the 5" of RMD blade is all edge and the 4.5 includes from the handle to the tip. The HRLM plays shorter than 4.5" to me. . . well, used to until I sold mine.
I'm tempted for a tanker/black paper RMD at this point. I love the handle, disliked the large choil last time I had one. But now. . . I could sell off my SAR5 for it. I think SR101 might be better in this size knife anyhow.
