Cutting Cardboard: An Observation

[Lenny]

I had to cut up a large box yesterday for fireplace kindling .
Had a Buck 110 with 420HC and a Para 2 with S30V.
I sharpened both to shaving sharpness prior to use.
Long story short, not surprisingly, the Para 2 stayed sharper much longer.
What was surprising, though, was that while the 110 was sharp, it sailed through the
cardboard like it wasn't even there.
I'm guessing the high hollow grind had something to do with it.

A lot of people swear by Spyderco's FFG, but I also find that I prefer a good hollow grind for slicing performance. From what I've read (and my memory could be cloudy), Buck did extensive studies with CATRA equipment and found the hollow grind to be the highest performer with all other variables constant.

I agree with hollow ground working better for cardboard. Less blade is resisting cardboard while flat ground makes more contact.

Blade geometry has as much to do with it as edge sharpness. When you get a great blade geometry with a great steel, now we're talking.
