Im sorry Im not following you. The Hinderer is high up there, but I need a titanium scale which he carries. How would you compare the Hinderer with 3.5" with a CRK Insingo?
I think Hinderer knives are one of the best production knives made plain and simple. Their fit, their balance, blade options, scale options (even titanium but I prefer carbon texture, carbon frag, or carbon reg because Ti sounds good, looks good, but doesn't feel as good as a lighter scale but YOMV) and all the changeable hardware. I can also use the pocket I have it clipped to with ease after learning how to put my xl hand in it.
It's hard to describe why it's really a better knife even after handling many many others. They can be had for $385 on the right day from the right place but most likely will be a flipper. The non flipper will cost whatever market value decides so..... Only Hinderer I've spent more on is a custom ground spanto 3.5" but that different market so moot.
The CRK all Ti knives are great but require sharpening and the insingo is by far my favorite blade by Reeve which I added a carbon scale to lol. His large insingo is a whole once lighter than a XM 3.5 without Ti scale so the weight of a full Ti XM18 will be even heavier than an ounce more than the CRK.
With all that said which one is the best is up to the individual. My favorite knives to carry are the XM 18 both 3" and 3.5" but if I were wearing dress pants my Anax or CRK would be pocketed. CRK is a totally different knife from pretty much all other Ti frame locks I have in that it's sleeker, smaller, lighter, thinner, tighter tolerances which only a true knife guy can see when taking apart/reassembly, the blade is thin but can be used rather hard (not by me but have seen some vids) but would require edge maintenance afterwards like any of my knives would get though. The XMs are closer to like a (I'm a knife that likes to be used (like striders in a way but not quite) )where CRK are more of an office desk mans user if that makes any sense but at the same time could be used for tough tasks if needed without worry.
The only thing that some of my ZT knives have over CRK or XMs is lock bar insert which I'm not able to judge advantage or the lack of one being a disadvantage.
So to break all that rambling down...a full Ti knife that is similar in design to XM (ZT, Strider, and few others) will be heavier, bigger in the pocket (but XM fits better than the others to me), and will have less grip in most cases than a textured scale which some Ti scales provide. Now the CRK is to me like a Rolex Yacht Master and the XM is like a submariner. Both could be worn with a suit but I'd wear the yacht master with a tux unlike the submariner; although, the submariner with a tux could be pulled off and has been done many times.
