I would be pretty sure the weight aspect will have a big "seperating" difference on these two knives...the .25 thick HG55 will be more of a DMCG type knife with the hollow ground being done to assist in slicing so there is less blade resistance...but the thickness will have you "convinced" you have a "tank" of a knife for heavy use.

My RMD's though are going to have the only "competition" I think from this knife as a small belt knife option for service use...

However...the edges my RMD's take are just "amazing"...

I actually cancelled my M9LE order I had for "two" because I figured with 2 FSH's and a Basic 9 it was getting "over subscribed" in that range...then I got a NMSFNO before they vanished as the combat price is excellent for Infi in that size of knife. Now that knife in Sage I don't regret as it is even more balanced and "ideal" I think than my FSH's but it is a close run thing...

I will say though that SR101 seems to take a sharper edge for me than Infi...or at least it takes it "easier"...my Jack Hammer is my sharpest Infi edge and my RMD's both cut paper without "catching" better than it....go figure???

Maybe it is just that SR101 responds really well to stropping with leather and green compound?? Certainly the edge on this steel suits a 5.5 inch knife and it's uses....very very impressive... up there with Cowry X steel and damascus R2...which cost an awful lot more...

But on a chopper Infi seems to come into it's own... especially once convexed...

My NMFBM just seems to be my immediate "choice" knife for any work of this nature. Infact it is a "lot" better balanced and powerful than I ever imagined it could be....I was very lucky picking one up at the last minute....the CG's were another really good value price for the amount of Infi you get!!
