Should I be using a toothy edge, or should I go for maximum refinement? This is a question many different people have asked and there have been many people with different answers.
The main point of this argument is to figure out whether or not an edge at a high refinement will last longer than an edge at low refinement. The theory is that a toothy edge may last longer because it isn't as delicate; and on the flip-side, a refined edge is supposed to last longer because there aren't as many "teeth" to rip out of the edge while cutting. Many will tell you that this is all "task dependent."
To get the ball rolling: What do you consider "toothy?" Some people consider 6,000 grit to be "toothy" while others consider that their finishing point. That should be a clear indicator that all of this is going to be a little opinionated, but I do feel there is some common ground in which we can all stand.
Do remember, the type of steel (and its carbide size) can affect the finish big-time, so try to remember all the variables when making your argument. Let's make this FUN!!
