I personally like a lot more titanium frame-locks without the steel insert, it will probably be beneficial to wear, but IMO the most beautiful thing about framelock it is simplicity; I strongly prefer the Reeve approach, the special treatment on the frame.
Or if this treatment it's too expensive I prefer the entire handle made by steel.
for future upgrades I will suggest:
-tip up, please do it; keep the military tip down out of the box (if you are worried about the "dangerous" tip up), but give us the option to choose
-bigger screws for the spacers, I don't understand the use of the tiny T6 on such a big knife, they strip easily & also aesthetically I find T8 (no need for mega screws ...just full size

) a better choice for the Millitary; also it would be nice to have T8 for the clip (with a new clip design Tip up dx-down dx, I will prefer 2 T8 than 3 T6), so you can use only 2 torx drivers to do the disassembly of the knife and work with full size screws ...for the "tiny" Military

.
With these upgrades It will be a must have for me
P.S: the steel insert was allready used in knives before the SR-1.
