sebenza pocket clip

The screw head access hole in the clips shown greatly reduces the cross sectional area at the point that the clip is flexed most. This is the reason that many deep carry clips have two ears with holes in them that are outside the profile of the clip. You could minimize the size of the hole by making it just large enough for a Torx bit and mounting the screw to the clip through an axial slot. Alternately you could swell the width of the clip around the hole to increase the cross sectional area at the stress point. Bicycle cone wrenches are made this way.

I find that thinning out the bend on the clip stops the clip flexing where the access hole is drilled. Making the access hole smaller would solve the problem but I have another fix in mind to get round that and all that goes with it. I use thicker Ti as well so I have more stock to play with when looking to engineer a flex point. I usually do full integral clips made from one piece of Ti with no bend, but I haven't made one for a CRK as yet. I and it seems most others like the original CRK clips just fine so it's never come up as a project to explore.
The clip flexing or where it's flexing is actually of little concern for the most part as the clip is under very small amounts of stress under normal use. The only time you will see any problems is if the clip is caught on something and bent out of shape. I think all pocket clips would be subject to that problem but Ti is rather more tolerant of being bent than steel is. I happens rarely in my experience but I have successfully bent Ti clips back to shape with few problems.
 
Nice job Haze! May I ask what kind of equipment you used to make that?
It might be easier to make if the pocket clip hole were filled (I believe there is an off the shelf piece from CRK for this?) and the clip that you make was bent down 1-2mm from the end (end that you have recessed in the clip pocket) just to stop side-to-side movement.
That is a nice job considering what you had to do to make it fit. No easy task whatsoever!

The clip was rough shaped on a regular 2" belt grinder. The top access hole was drilled before bending and the second hole for the screw was plotted from the first hole after bending. It was bent by hand using round nose pliers and a little bit of hammering, with appropriate heating of course. It was then finaly shaped, cleaned up and tweaked on the grinder and then hand sanded to 600 and finished with a green scotch pad. That is usually a good enough prep before blasting but you could take it up to 800 or 1000 grit if you really wanted to get all the scratches out.

I hear what you're saying about using the clip insert to avoid all the fitting done on the back side but it fills the whole recess on the handle so would need to be modified to accept the clip tab, or what ever you want to call it. It may well be easier to do that, but my concern was that even a little bit of a wiggle pisses most cutomers off and I want to use as few parts as possible. Using the recess in the handle allows one to keep the clip totally solid. It also keeps the inside of the clip clean and flush as well as the over all height of the clip to a minimum.

An alternative would be to drill and tap the insert 2x and affix the clip to the insert, then the insert to the handle. Just thinking out loud...well..because I want one :)
 
Well, if any one here can manage to make one I think it would be you old chap. :p:thumbup:

I want to make more from 2mm thick Ti sheet and thin out particular areas to get it flexible, stong and well fitted in all the right places. Still thinking though.........:)

LOL! Yes..I may be able to make one..But my forte' is mill's and lathes. Dealing with sheetmetal is a pain when it's 5052 aluminum...That says nothing of Ti, which I have never had any experience with in sheetmetal form. I do have a few sheets of the thin stuff laying around..Maybe I will give it a shot. That might have to wait until school is out at the end of December.

I like the sound of that!
 
If you want to try one give me a shout and I can send you some dirty pictures exposing the whole clip. As you well know it is much easier to fit something if you can see what you're aiming for in terms of shape and form. I'll probably make more but it will be a couple of months before my bench is clear and ready for new stuff......maybe it is time to change the colour of my name here. :D

Once one of you starts making them please send me an email, I'd like to buy a few.
 
Hi guys I know this has been an old post and I've yet to find this topic anywhere else as of this date has anyone been fabricating a low ride clip for the CRK yet? Thanks
 
thanks 1shot that does look pretty cool. anyone know which spyderco would have a wire clip that might fit a large micarta? thanks =)

I believe all clips and inserts are the same for small and large sebenzas... so this would work on a large. However due to it's size, it would probably look and feel weird on a large.

The wire clip that is used for most of their knives actually kinda sucks on the sebenza. The regular wire clip like seen on the Sage has a bit of play even tightened down. The one from the thread above is from a meerkat, very different clips. The one from the meerkat is shorter in length, but much stouter. Tightened down it's very stable, there is no play and retention is very tight. Been using this clip for on my user seb for six months now. Retention is still super tight and no problems to report.

If you sand blast the meerkat clip you can get it to match the blasted scale pretty well. The clip is just ever so slightly lighter. This is a good solution for anyone who wants a lower riding clip. However it isn't as low as one you'd get that was custom made. As you can see in the pic below, still sticks out of your pocket but much less than stock. I dig it a lot, working as a solution till I find someone to make a custom.


I personally am still looking for a custom solution so I'm glad this thread is seeing some daylight. I'd love to get one like Lone's or Haze.

Really appreciate the input smi but I think I'm going to try and fabricate my own been searching around for some TI I work in a machine shop so I'll have access to some tools and see what I came come up with will def keep you guys up to date if it falls thru

If you can make one like those on the first page, I'll be your first customer lol.

Really digging the design on Lone_Wolfe's, cool shape.
