Hi everyone.
My first post.
I bought a 3D printer last week and the first thing I had to make was a knife.

I cannot say this is finished, there still are parts need to be modified.
However with some drilling and sanding, it is a fully functional model.

I put up youtube video, so check out how it works. It's pretty cool.

Well, this is not exactly finished piece,
I still have many things to learn, and I am not even sure if it is going to work for other printers.

However, if you really want to try.

1. layer thickness is 0.2 mm

2. I made custom supports for some parts. you need to remove them after print.

• it requires sanding...
• and drilling...

3. (cannot be done with printer) you need springs. one 4mm diameter tension spring, and two custom made spring which I made by my self with guitar string.
