Cutter / knife with segmented blade

Version 0.9: 6 January 2017
I finally got around to redesigning the slider. It holds its spring a lot longer than the one in version 0.8. Although eventually it tends to come to loose. The only way I found to solve this is to put a small spring in the button. So the two flanges are pushed outwards. It's also just one part now instead of two. With that I had to slightly alter the upper and lower body. So these parts are not compatible anymore with version 0.8 parts. The first slide in and out could be tough but it should be fine after that.
I'll leave version 0.8 online for people who want replacement parts. The knife stand of version 0.8 is compatible with all versions so also with version 0.9.
It works reasonably well right now so I will stop calling it a work in progress. Although I would consider Version 1 to be a final version I am not sure I will have the time to ever get there. So lets consider 0.9 a final version .... for now ....

Version 0.8.1: 13 July 2015
As promised I uploaded the adjusted knife stand.

Version 0.8: 12 July 2015
This update removes the end piece. It was an overly complex way to hold the upper and lower body together. With that the blade snap off option is gone but soon in version 0.8.1 I will also update the knife stand and include a snap off in the base. The stand is a bit tight so will fix that too while I am at it.
I removed the assembly video…
