i'm surprised this one hasnt come up yet.the biggest difference is obviously the micarta vs. the res-c mudders although i dont really know the exact specs for both but they both got 5in blades and are of the same steel which is my 2nd favorite hard use knife steel behind INFI.

i personally think i might like the protruding tang and micarta of the HRLM better but i wont know until i get a S5 in my hands.res-c just doesnt have the life of micarta.it can get worn down,gouged,cut,whatever.the res-c on my DFLE is smooth as butter and has small chunks missing from it.

its all my fault but micarta is just tougher.

the S5 is one hell of a knife though for sure.
