Daryl Weir filed a BMT saw ... pictures ... bmt_hand_front.jpg Photo by daryl_weir | Photobucket
I'm sure I remember a detailing posting on (guessing) woodnet about it.
Isaac gave an example of a front-fleamed tooth with the back of the tooth straight across, by sloping the file and consequently the gullets.
Stewie said he thought fleam weakened little teeth. There is the converse to Isaac's scenario - also through sloping the file - such that the front of the tooth is square across, but the back of the tooth is angled (or 'fleamed' if you like). So instead of the point-slope decreasing as in Isaac's example, some point-slope is introduced where there would otherwise be just the flat across top of a normal rip tooth.
I'd be intrigued to know whether that had any worthwhile effect for tiny teeth.
Daryl mentions that filing profile here (Old Vintage Antique Saws Restored) in discussing the Simonds #5 handsaw.
BTW he also has a Disston #4 (12ppi) there that he describes as 'filed hybrid'. "This is a smooth cutting saw meant to work in either rip or cross cutting. "
There are plenty of pictures ... Disston No.4 16" by daryl_weir | Photobucket
Finally ... the Disston D17 "double duty" saw wasn't too different from the others mentioned (Online Reference of Disston Saws -- D-17 Saws)
MarvW had an interesting view on it pretty recently (WoodNet Forums: Saw Sharpening Advice - Atkins 93)
"I have had the misfortune of filing a couple of those type saws. They are in fact meant for double duty, ripping and crosscutting. If all you want is to use it for rough cutting, it will do exactly that. Due to there being way more crosscut teeth than there are rip teeth, the saw will rip pretty much the same as if you were using a crosscut saw. When you crosscut with it, the deep gullets act as if there is a missing tooth every 7th tooth. The gap, along with the two rip teeth it does about the worse job of crosscutting imaginable when sawing anything less than 4/4. I hated the saw and wouldn't recommend it even to someone I don't like. It might do ok in thicker stock. "
Cheers,
Paul

Nice work Paul. Enjoyed the reading. I agree with Marv on his comments about the Atkins 93. The one I had was terrible to use. The only decent part of the saw was the handle with its wonderful detailed carvings. I ended up cutting the blade down to the size of a panel saw, and retoothing it to a high tpi rip saw. I really enjoy using this saw now.
