That is true, they cut green wood GREAT... and the cut is nice, not a splinter with a rip up 1ft from busting it by hand.

When I was a kid I used the crap out of my SAK saw, and it was barely 3" if that... 4.2" will be pretty darn nice. We used to make shelters, dam up streams and small rivers, make things to trap fish, etc.. it really was used A LOT. Thus why I want one on a wilderness SAK. (Combined with a fixed blade for `hacking` the saw could prove useful for the finer side.)
