    That will help with twisting and fiber pull out but won't do a thing to prevent chairing.

    I have been using the open face notch, and conventional. I dont have any knock on the homboldt, and will begin to try it. I see some advantages to it......and I learned alot from the series here.
    I was searching around about Leaning tree's and found this thread and found it interesting. I have not experienced a Barber chair, and I am thankful.

    the triangle is illustrated here.....

    The open face cut is listed as safest by OSHA. https://www.osha.gov/SLTC/etools/logging/manual/felling/cuts/notches.html
