That's pretty slick, Burncycle.

For a small saw, I put one of these in a kit: http://countycomm.com/seresaw.html . I also really like the wood saw and filesaw on my Leatherman Wave. My biggest kit has a Gerber Sportsman's Saw, but while I'd expect it to cut about as well as what you built, it's much buikier.

I have no affiliation with CountyComm, Leatherman or Gerber other than as a customer.
