Manual Chainsaw

[rolnor]

I got this manual chainsaw, its unbelievable, I cut cut down a 10cm tree in under a minute, great stuff. Its pocket-size, weighs nothing…

Can you build this out of an ordinary chainsaw chain?

Doesn't look like it would be the same. Every two teeth, the direction of them is reversed so it cuts in both directions. There are also spacer links that I assume allow more force to be applied to the cutting teeth for deeper slower cuts. It looks specifically designed for human power.
