Knife sharpening at i3detroit Answered

I attended a free i3 class on how to sharpen and hone your knives (I was the new kid with the hat) and I took some video. I will do a more through writeup in the ible when I get around to it, but when I do, who do I credit/link to?

Also I learned a lot at the class, thanks guys!

Thanks for coming, Ideanator! As one of i3Detroit's founding members, I can't tell you how gratifying it is to see the overflow parking almost fill up. We try to have a wide variety of classes that attract an interesting bunch of people, and last night certainly had that! I really hope you'll pursue that diaphragm valve we talked about, as I've never seen one operate in person.

I'm working on the reminder blog post for tomorrow's antenna class, too. It's an entry-level make-and-take for some of our curious newbies, and I likely won't have time to do much filming, but I hope to establish a tradition by which more of our classes are better documented. We're not always subject-matter experts in everything we teach (though Dustin certainly is on knives!), but regardless, recording this stuff can't hurt.

Hope to see you around the space again soon!

I'll probably come by again before I get the sharpening ible and video(s) out. Video would be really nice, maybe copy off some of the geek groups stuff, they made a nice looking camera crane out of 2x4s if you added pitch and yaw to the camera mount via steppers or servos...
Anyway yea, i3 is cool and i will come again, probably to mess with your fancy soldering stations.

There are surgeons who now use a scalpel that is a bit of flint, and they 'nap' it to sharpen it. It cuts like a razor, and the cuts are not the perfect smooth line of a blade, but a micro fine but slightly jagged cut that actually heals with less of a scar. As pointed out above, the rougher cut actually heals better then a smooth cut. If you ever play around with 'napping a flint edge, you will learn just how sharp these edges are, they make many 'razor-sharp' edges look dull in comparison! At a Mountain Man get together a few years back, I saw a guy dress out a deer with a flint knife and he did it faster then another guy using a good steel blade with a freshly sharpened 'razor sharp' edge. As there was a hundred dollar bet on the outcome, both men were doing their best to win! Shows you that an old 'technology' is not necessarily outdated. By the way, the 'flint' knife was made of stone taken from the stream in the campsite and made that day, so it was not something extra hard or special.

Seems a bit counter intuitive for a place like Detroit, putting on classes about sharpening your shank :)

. A dull knife rips and tears. A sharp knife makes the doctor's job easier in the ER. :)

Only good thing about a cut from a dull knife is, pull the edges together and it heals in a jiffy. a sharp cut takes forever and is endlessly reopening.

I prefer having my sharpened implements very sharp so they can just slip in and out effortlessly as opposed to needing to force them in.
