Different knife shapes,and edges require different technics to be effective. No one shape or size or edge grind is going to work "best" for everyone to do everything. That is part of what I love about tools. How does this, thingamajig, work for me? What can I learn from you to make the tool work for me? What jobs does it do better than the tool I am currently using? And what adaptations can I make to work it better?
Gun's, kinves, flashlights, woodworking tools, whatever we all have our own ways of making them effective for US.
