Unlined CF knife

#1

Post by npueppke »

I just thought of something, maybe I'm not the first but what about an unlined CF knife? If you squeeze a Sage 1 together there is almost no flex in the handle scale so it's definitely got the stiffness to support itself, and I think CF is fairly lightweight so it would appeal to the featherweight knife fanatics.

Looking at the sage now because it's right in front of me, I think you could use the same 'pillar' type of spacers, and put in a partial liner to support the stop pin and pivot and presto. I suppose they would have to be nested and you would have to use something like a backlock, but anyways, it's just a thought.

The original argument against unlined CF, G-10, and micarta was that none of them retain clip screws worth a ****. The success of the new style wire clips on the unlined UKPK suggests that issue can be overcome. Flex is a relatively minor issue which can be overcome by using thicker material. However the Sage does have dual liners, so I'm not sure what bearing its rigidity has on anything.

The CF Walker is unlined on one side so I guess it's possible, but it leads to clip problems, as Paul said. I think the Walker only has clip mounts on the lined side? But perhaps the UK style clip mounting would work if they put something behind the liner in the same way. I'm not sure how incredibly much lighter it would be though; a recent thread about CF and G10 weight pretty much concluded the difference is negligible, so any real weight savings would have to come from being able to use thinner material due to superior strength.

Right, but on the Sage nothing screws into the liners, the clip screws screw directly into the 'pillars', no problem. You just mill a hole into the CF instead of into the steel to support the pillars. The clip itself is supported by the CF alone, so if CF is as tough as it is made out to be there should be no problem. Anyways it was just a thought.

I have an unlined Renegade and all but one of the UKPKs. I've used two of the UKPKs pretty hard. I did notice that that there is a bit of flex and it seemed to encourage the pivot to loosen up a little. I tightened and all is well. There didn't seem to be any "permanent" change.

I work with CF fairly frequently and I do not think there would be much success in stabily drilling and mounting pillars. You would need thick scales in order for it to work, CF is strong for its weight, but it tends to be fairly brittle when you start drilling/milling it. Individual fibers can get pulled up and torn away from the bulk of the material.

Yay for accounts being approved!
