PlumasDePan, Pete's spreadsheet has some angle results by steel, and I got some insight from the VLOG's as he went to 12 degrees.
Watched Pete's m390 video a couple times, and the M2 test just now. His results, the BF link, comments and SEM's above, make me scratch my head thinking what questions would answers directly his two impressive ~1000 cut test results.
His spreadsheet of past m390 / M4 rope cut tests reports ~400 thru ~800 cuts. Pete's often stated caveat regarding his results - a dude in his garage testing edges-, argues for understanding results as trends, patterns and principals, not doctoral research. Gab's written and oral reports, efforts, and satisfaction leave questions, even though he demonstrates that toothy edges have there place.
Could different results be attributed to the following? And what am I missing?:
- Pete's sharpening procedure results for Benchmade's m390 / M4 vs. Gab's procedure, within Pete's testing methods-
- Beyond comments characterizing 6k silica stones effect on m390 /M4, and comments / images of burnishing vs grinding Maxamet with Wicked Edge's 600 diamond grit, is there any effects from Gab's apex creation using different stone types for each side? - diamond for 70µ side, and silica's 3µ side.
- Gab's procedure is similar to several other techniques mentioned above, taking advantage of bevel face counts / facets treatments to increase and maintain cutting effectiveness.
- Production of an "open edge" thin geometry scalpel, treating both sides differently ("open edge" scalpel blade describes a surgical blade ground on both sides, but only finished on one.... comes with microscopic teeth along the blade’s cutting edge, which gives a surgeon a consistent feel while making an incision. Open-edge blades tend to be more durable and hold their edges longer.") usamedicalsurgical
- Missing info-
- Gab's m390 / M4 grind angle;
- specific start state for edge tested before Gab applied procedure;
- Gab does not report his own before and after results, but states generally " it's given him great results in edge retention."
Aside - finishing up Tufft's "Beautiful Evidence" to help the family understand the gulf between signal and noise, beauty and base, truth and lie, and want to say thx to folks (Pete and Gab Et al.) attempting to increase signal, beauty, and truth. Stay free, out of our liberty we stand with hope-
