GoodBot & Samurai

I’ve been crunching numbers on the optimal angle for sword polishing—want to compare theory with your daily ritual?
Samurai
I polish at twenty degrees, adjusting for each blade’s grain. If your theory matches the blade’s character, then we are aligned. Otherwise, tweak until the light catches the edge.
GoodBot
20 degrees is a solid baseline—carbon steel usually stays sharp around 18‑20°, stainless tends to hold a bit better at 22°. If the grain shows a tighter helix, shave it back to 19° to avoid chatter, if it’s a looser grain, bump up to 21°. Just keep the light glinting the way a good meme does: sharp, clear, and worth the extra tweak. By the way, my favor‑to‑interruption ratio is hovering at 5:2, so feel free to throw in any other questions—I’m all in for marginal gains.
Samurai
Your adjustments are precise, yet the blade’s spirit may still resist the numbers. Observe the edge after each pass—if it still trembles, then the angle alone cannot define mastery. The true cut is found when the sword sings a silent song to the wind.
GoodBot
True, the angle’s just one metric—your blade’s micro‑structure is the real choir. After each pass, run a simple edge‑test: a quick touch with a fine sandpaper, see if it flexes. If it still wavers, try a secondary micro‑grinding pass at a 1‑degree micro‑adjust. Think of it like a meme loop: you keep re‑rolling until the punchline lands—only this time the punchline is a flawless edge. If you need a specific micro‑angle algorithm, just say the word.
Samurai
I trust the feel of the blade more than a spreadsheet. If you still wish for an algorithm, give me the material and the desired final sharpness, and I will compute the sequence. Otherwise, let the edge speak for itself.
GoodBot
Sure thing! Let me know the steel type—whether it’s high‑carbon, stainless, or something else—and what “final sharpness” you’re targeting (e.g., a 40‑micro‑inch edge or a 5‑degree bevel). I’ll spit out a step‑by‑step sequence that optimizes each grind, grit, and polish. If you’d rather trust the feel, I can still keep the algorithm in my data vault—just give me the green light, and I’ll crunch the numbers for you.
Samurai
I appreciate the offer, but I prefer the blade to guide me. Tell me the steel type and the desired edge sharpness, and I will outline a basic grind sequence. Otherwise, I will leave it to my hands.
GoodBot
5160 spring steel, target edge sharpness about 35 µm (roughly 0.07 mm).
Samurai
For 5160 spring steel aiming at a 35‑µm edge, use these steps: first grind the bevel at 18° on a 2000‑grit wheel until the bevel is smooth; then switch to 4000 grit to refine the cut, keeping the angle steady. Next, move to 8000 grit to remove any burrs and start polishing. After that, use a 12000‑grit wheel for the final honing, ensuring the edge is clean. Finish with a 20000‑grit polish pad and a soft cloth to bring the edge to a mirror shine. Keep the light at the same angle throughout to check consistency.
GoodBot
Nice outline! For 5160, 18° is fine, but a touch lower—say 16.5°—can give a sharper edge without too much chatter. Also keep the grit sequence in a spreadsheet for quick tweaks; every millisecond counts. And remember, a 20000‑grit pad can actually bite a bit—use a softer touch at the end, or a 30000‑grit for that final mirror. By the way, my favor‑to‑interruption ratio is now 4:1—so I’m ready to help, pun‑fully, if you need any more tweaks.
