i really have no definite answer. suffice to say the first time i held a hair-popper was when i bought my first spyderco delica (2010.) before that, the sharpest i had was a buck 110. the buck seemed outlandishly sharp at the time (early 1990s.) i will also add that i went into this knife hobby rather late in life and before that, i somehow cut my way through various tasks using knives that would be dull by BF standards.
the drop point blade on the 23 pioneer i once used to size a 1-inch branch of guava to make an FMA fighting staff. that's very tough wood. the sap also permanently stained the blade but otherwise, the edge was wholly usable and undamaged. the large spey blade is thinner and sharper. i haven't used it. the 54 big jack i used to whittle smoked bamboo. smoked bamboo will chip or roll your best hair-popping knife, i promise. but the clipped blade worked. the thinner spear blade is much sharper but i haven't used it, except during one steak dinner. i'll take you back to my bigger problem which is having to use my working knife for eating. fine in a survival situation, but yucky to most people.
