Sounds the same as what I see, although I’ve never pushed a finisher as far as you. Maybe mine would undercut eventually but I never got that far. 20 minutes ago I shaved with a great 12k edge that I bet wasn’t undercutting like a demon, so it can’t matter all that much.Great undercut up through my polishing stone, an old King s-3, which I’m told polishes closer to 8k. Nothing in the coti.
I did a quick hone with a test razor today and this is what I saw.
Wester Bros 5/8. EBay special that had a bad frown when I got it. It’s still kinda there now that I look at it again. I know what you’re going to say @H Brad Boonshaft and I agree the heel does need correction
Maybe 20 laps on 8k shapton glass and it’s undercutting nicely
Now onto a coti with light slurry from a bout. It took 5-10 laps to get there and it undercuts, but not as strong as the 8k.
I stayed with the slurry for a while and diluted it down, and the undercut got better but was never as good as it was on the 8k. I should have take a picture then.
I washed off the stone and blade then honed on clear water. Nothing, and it never got there. It’s hard to see but the blade is pushing a wave of water in front of it.
Maybe it would have got there eventually, or I should have stayed with the slurry longer. I guess this where I think there’s room for some improvement. Or is a weak undercut just what some stones do?
