Little sanmai ko deba test knife. Better go shoot some fish this weekend to try her out with.

I've been developing a template in Fusion 360 to design frame lock and liner lock knives. I finally got it to the point where I can put in all my specifications like pivot size, bearing dimensions, etc and it updates my drawings. I can then focus on the design aspects of it. The final files I can then use to print a prototype and ultimately order water jetted parts.

Feel like sharing any files for it? Or tips on how you approached it? I've just started messing around with Fusion 360 for metal fabrication projects, but I'm planning on using it for frame lock and liner locks too.
 
A custom order for #austria. 210x50 with horn, stainless spacer and ironwood. Part of the spine left flat to scrape the cutting board. Handle shape half round on the bottom. I was told this is called “rokkaku honmaru”. 26c3 and wrought iron

Not sure what your background is but for me the learning curve was steep. I did a few tutorials a day of whatever interested me on YouTube but ultimately I hired a engineering student as a tutor who I could ask questions to and collaborate on design solutions. I'd be happy to share his contact information with you if you would like. I still meet with him ad hoc to workout issues.

One of the biggest problems I faced was the inability to reference critical dimensions because they were created later in the timeline. Ultimately what I came up with for a solution was to capture all those key dimensions and relationships in the template first component. One drawing in that component addresses the pivot and stop and cutout for the stop pin. Another covers the detent pin, Another captures the end of the lock bar and how it relates to the cutout for it in the blade.

Besides that timeline/critical dimensions issue I also realized that it is critical to make sure I was constraining drawings properly so they worked well with the parametric functions in Fusion360. When you change the size of the bearing dimensions you want everything to adjust around that and optimize the space for the lock pin cutout etc.

I'm considering using my template to offer custom design services so I think I'll have to pass on giving it away for now. But if I can help you in someway - let me know.
 
A little prototype mockup of a keychain puukko idea I have. I’ve struggled with a retention idea that fits my practical & design criteria. This is my solution. You are looking at a cutaway of half of the knife. Knife & sheath are intended to butt up & mate seamlessly…..or as seamlessly as I can make it. Link to 13 sec video:


The flat spring will retain the blade by pushing against a gimping slot in the spine. I only have a tiny notch cut in the video, but I can already see I need to carefully plan the geometry of the retention gimp to ensure continuous tension pulling the knife into the scabbard to get the “seamless” look I want. Any ideas are appreciated!
 
^that's friggin cool, ole Blackie Collins would be impressed
 
Interesting, what do you use as a spring?
On the other hand, a well made sheath will hold it's knife
