Recreated the full knife.

• Body has now hexagon cutouts. This prevents the blade blocking at the long slots in original part.

• Body is now held together on 2 sides so knife will not open on its own.

• Reinforced the Body where the Body pieces lock together. Original broke pretty easily

• Knife is now Trapezoidal as found on Printables(maybe original will follow but there is another remix by DethBringa that works just fine) @DethBringa Thanks for the Idea at the Spring.

Slide Coil and Lock are original parts. Just in here for easier Download.

Have fun printing..

Tested the new design today. Comes out great and works fine

Hint: For easier assembly put the Body parts together at the front(where blade comes out) first. The Block at the side usually comes in automatically, sometimes it needs a little push.

At last put the parts at the back together by bending top part a little and get that latch in from the inside. this gives less stress to the latch.

Added a Comb due to request
Added a Ruler due to request -> i didnt print it yet but i can see in slicer that 0.1mm layer height is necessary. otherwise the slots will disappear. ideally go for a nozzle with smaller diameter but 0.4mm could work.
Added rounded blade
