I feel like I've been making some progress on my straight razor use and honing techniques. I've got a couple blades that I've been working on with a C12K and I think I've got really decent edges on them. They compare well to a couple I had honed by Glen, aka @gssixgun . I'm getting a really good comfortable shave with them everywhere except my chin. The dense and large diameter whiskers there just don't want to cut easily. I can go over my chin a dozen times trying different things like guillotine strokes, scything strokes, shallower and steeper angles, etc, but I still leave a whole bunch of whiskers behind. A good sharp DE or injector blade takes those whiskers right off so I feel like what I need is more sharpness from my straight. So my question is how can I get a sharper edge? I've tried CrOx on a pasted strop and 6 or 7 strokes doesn't seem to make a lot of difference. I've also tried 20 or 30 no-pressure laps on the C12K with a little slurry and without. Again, not much difference. I think my C12K is a fairly good one based on Glen's descriptions. It's not ridiculously hard but also doesn't raise a slurry when making water-only laps with a razor. Should I try a different finisher to get more sharpness. Maybe diamond spray? I've read that it can make a harsh edge but at this point, I think I might be willing to give up some smoothness for more sharpness if that's a choice I have to make. Thanks for the help everyone.
