What's your opinion of the three-faceted cutters with flat knife edges? Do they have more or less drag than traditionally sharpened two facet cutters? Do they wear slower in use?
Actually the jury is still out on that. I only sharpened one set of cutters that way and I can not notice the difference. Off hand I'd bet there is a little more drag but resharpening may be easier with the knife edges because the overall length of the tooth should last a lot longer. That would greatly reduce the requirement to joint.

Hi Jim,my name is brother ben.i was reading your post here. What i wanted to ask is reguarding your saw binding after so much depth into the log.you made a reference to your filing but i couldnt understand where the error was made. I experience that often. I confess i dont level the saw plate too well. I have been checking my set .012 on a flat ground saw. Ive thought my filing on the cutters may be suspect. If you dont mind explaining this detail i would appreceate it. Also i saw your video cutting fire wood. I was sure encouraged seeing you cut staight into the log without pealing the bark. Thank you friend,brother Ben

Saw binding could be caused by a few things but for a flat (non-tapered) saw I'd increase the set to about 0.020". For a well tapered saw a set of 0.012" or less is just fine but a flat saw needs more set. Dull cutters may also tend to bind because the kerf will tend to get smaller as the saw cut down into the log.
Normally I don't peal the bark unless I suspect it is dirty.

Thank you Jim. I will increase my set to .02. I confess ive never set a saw to that measurement. These flat ground saws are old curtis one man saws (36 in. and 42 in. )Champion tooth pattern.They have been good saws. We cut mostly hard wood out here in the mid west. Im greatful for your help.
