If you just want a blade to cut open boxes or a really cool knife to show off, you need look no further. This little knife will do all that and so much more! It's very small and at just over the size of a standard razer blade, it can fit almost anywhere. It also features a very smooth sliding action, with 2 blade positions, (not counting the closed position). This Compact OTF Knife is a quick easy print requiring no supports or post processing. Feel free to print a lot of them, you'll love having them around! 

If you're worried about kids finding these too easy to use, i have included a printable blade that can cut tape but is not sharp enough to cut flesh, unless driven in by hammer :) If kids or crazy adults are not a concern, this knife is also compatible with razer blades.

Assembly Instructions:

1. Install the Locator Spring into the slot in the Casing
2. Place Blade into Blade Carriage and lock it into place with the Blade Locking Plate
3. Slide the Blade Assembly into the Casing
4. Print another and repeat ;)

Printing instructions:

.16 layer height works the best; it will give you the best look and it has the best tolerance.

15% infill seems so work just fine with plenty of strength.

2 perimeters works great.

And finally the filaments that i have down below work the best but basically any PLA matte will work great and PLA basic and finally PETG works great but feel free to experiment. Enjoy!
