I also acquired the distain of pastes, sprays and tape. 'Most likely from the biases of those I've learned from. Its unlike me to continue that way as its too close to rejecting tools that can help. I've tasted good dilucot. I was clearly in the ballpark w/ the N-asagi. But I cannot get it as reliably with the coti finish. This gives me pause about tape, which I used to use and stopped.
In the last couple days, I've used coti, BBW, C12k and asagi and gotten fine edges on each. Like Black & Tan, I've started wading into pastes and various slime. One happy discovery is that the slurry from a stone painted on a canvas/linen strop does retain the personality of that stone. I've not tried slurry from a coti yet, but the asagi and C12k. If I want more smoothness 'cause I finished on the C12k, I give about 20 strokes on the asagi strop. If I want more crispy, 'cause I finished on coti or asagi, a few strokes on the C12k slurried strop gives it. An the slurry is a free byproduct.
If a honemeister is correct, the order of platforms for pastes/sprays: felt, webbing, linen/canvas, leather, balsa will tend to give an increasing chance of harshness. So the asagi strop gives such smoothness, the next experiment will be asagi slurry on balsa.
Now, I will have to go back and try more unicot. Has anyone tried it w/ Emmanuel's Turp/wax coating? If not, I will.
BTW Gary, Thank You for all your kind help on this and other posts. Your objectivity and willingness to try the unorthodox are much appreciated.
