I agree the TK1/Tk2 are a thinner edge and may be what I'm looking for. I just wonder how the new F1 Pro edge compares to the original F1. I'd like to get the benefits of the Laminated CoS and a little thinner edge than the original F1. The pictures look thinner but what has been your experience?
The geometry of the very cutting edge feels like the F1 Pro is slightly thinner than my VG-10 F1.
It bites deeper into wood than the F1.
When I get a new knife, I mostly thin the edge until it bites wood with as little resistance as the grind permits.
I have done that also to the F1 Pro and it's better than the VG-10 F1, but the F1 3G is better than the F1 Pro.
I think it's mostly about how the user shapes the edge, rather than what edge it has right out of the box.
If I compare my Fällkniven 4" models with a thinly ground convex blade like the Hess Tiburon, there's a clear difference.
The Tiburon is a dedicated slicer in 1095 carbon steel and it bites wood really deep.
Too deep I think, because it doesn't break away the woodchips as easily as a thicker geometry.
This could be cured by giving the edge a slightly thicker edgeprofile, but I like it as it is.
It's good to have knives with differrent properties.
For being marketed as a thick survival knife, the F1 Pro of course has plenty of rough cutting power but also possibility for more detailed work.
