Recently I have spent some time in the Alps and have had opportunity to observe the house lord by splitting fire wood.
I was surprised how sharp the splitting wedge was. I did not have my PT50B with me, so I can only guess that it was not to much more than 2000 gf.
The other thing that surprised me was the acute angle of the wedge, some 35°. It is the same edge angle we are sharpening on the majority of our knives.
Narrow edge angle guaranties large mechanical advantage of the wedge, but on other hand friction may bind narrow wedge more easily than a wide one.
