I really liked the design and locking mechanism of the faker knife by woodencreationz, but had a couple of issues with it:

• a mesh error in one of the two handle pieces, which was fixed with meshmixer (last two images)
• the slot in the blade holder couldn't actually hold a blade (the slot was too thin and the angle of the blade wasn't right), I also moved the blade back 1mm, so its tip wouldn't stick out from the knife when closed

If you print this, make sure to orient the little spring correctly, it has a little step on one side, this should be printed facing up and installed like in the pictures
