EDC XIII Which knife or knives are you carrying today?

Can't remember the last time I carried the same folder all week. It's been fun. I can already tell this is going to end up being an "old friend" one day, with a small handful of others in my collection.

Great design ; nice clean look/ keeps screws from backing out .
I have had the pivot action go to hell on knives that were designed to have a back spacer and then the company eliminated the spacer in the new version .
e.g., Benchmade 710 M390 Blue and Black laminated G-10
I hope yours is happy.
Thanks for the knife compliment and commentary. As for the lock bar screws hidden under the clip, that's really a cosmetic thing rather than a way to keep them from backing out. The forward screw is pinched by the clip's tip but the rearward one doesn't touch. As there's very little thread in the fairly thin lock
bar, I had to be very careful when I torqued the screws in hard after removing the bar to lighten the overly stiff detent which was a bit of a forefinger-wrecker.

As to backspacers providing stability between the scales to maintain proper action, there are a couple different sorts that may or may not provide that. The Leader's spacer was secured in place by a couple pins that floated in bottomed-out holes in the CF scale slabs and thus provided no hard connection between them. The action is fine on that knife. I have several other knives--Russians and Olamics--with floating backspacers, though I haven't removed any of those.

The other sort backspacer does function to tie the scales or slabs together and would be considered structural. The 710 is like that and I saw your thread about correcting the poor action on your -1401 which you felt came from BMK's design change to stand-offs on that model. I'm glad you found a solution that works for you. My -1401 was always "happy" and of course now wears holey Arizona Ironwood pants with replacement non-blue standoffs provided by Keyman, who made those scales.

I've got a number of knives that I've converted to open-back by removing backspacers--another 710, a Barrage, and a Crooked River, for example--and none of those have suffered poorer action as a result. I've also found that it's easier to fix centering issues by scale shifting on knives with stand-offs than those with structural backspacers.

Lastly, I have a bunch of Griptilians, whose stock config's with the Noryl scales do not have backspacers, but the handles, with their nested liners, are directly connected one to the other. My four with Wilkins aftermarket scales are still connected hard by Kevin's generous butt spacers, my one with Igorded's are just stand-offs now, and my 551-1 is open back with stand-offs as made by BMK, similar to the 710-1401 that gave you trouble. All those Grips and my others mentioned above function great. Maybe you were just unlucky. 😥
