Question 1

What is the thickness of the saw blade?

Accepted Answer

If I remember right, the blade is .021". Each tooth is offset .002". But check the specs on his website to be sure. I also have the veritas saw with 21tpi and this saw is much better.

Question 2

It looks like the handle is riveted to the plate, which means it can't be tightened.  How is the handle attached to the plate?

Accepted Answer

There is a lengthy youtube video where he shows you every step of making the saw. Look uo making Cosman Saw. Its a 50 minute video.

Question 3

Dear Rob, Can the saw be sharpened & how is quality vs. true usable life expectancy

Accepted Answer

This is not Rob but it can be sharpened using a file. As to the life of the saw, it will depend on how often you use it and how you store it.  It can last a lifetime if cared for correctly or it could last less than a year if abused and not or left out, ect.  Here is more info about this saw:  
Rob Cosman has been woodworking for most of his life. While earning a B.Sc. in Industrial Technology/Furniture Design at Brigham Young University, he was Dr. Dale L. Nish's teaching assistant. Rob has also worked with many of the world's best craftsmen – including Alan Peters, Sam Maloof, Tage Frid, Monroe Robinson and Peter Korn. After teaching thousands of students to cut dovetails by hand, Rob saw the many problems people had when using traditional dovetails saws. With the goal of enabling woodworkers to assemble their dovetails straight from the saw, Rob designed and developed this dovetail saw to address the problems he had seen. The first two inches of the blade has super-fine, 22 TPI for ease of starting the cut, while the remainder of the blade has more aggressive 15 TPI for finishing the cut quickly. With an extra-heavy brass back and an overall weight of 22 oz., versus 13 oz. of other high-end dovetail saws, the saw itself provides the downward pressure for smooth, vibration-free cuts. Composite handles have carved finger recesses for a comfortable fit in the hand. A slight .002 inch (per side) set makes for dead-straight saw cuts and produces a .024 inch kerf. Each saw is personally tested by Rob prior to shipping. Overall saw length is 15-1/8", blade length is 10", cutting depth is 1-5/8".
