Training for a job at Cincinnati Milling Machine company (later Cincinnati Milacron) in 1973, I was taught never to pull the edge from the stone, rather to always push the edge towards the stones. Supposedly, pulling rips the microcrystalline lattice apart, whereas pushing the edge hardens the edge and provides a smoother, more durable blade. However, I find it very difficult to maintain the proper angle when pushing, so I use a jig. Any metallurgy experts' thoughts are more than welcome! Cheers, happy luthiery!

That's what I like to see.......honing in on some really sharp technique........

Hi Kevin, Again kudo's on your depth of knowledge and your teaching style. Flawless delivery. I'm a fan. If there were an Academy Award show for You Tube , you would be the MC every year. BTW I'm up here in Ontario not far from you and if ever you should need anything from Lee Valley , I would be delighted to go pick it up and UPS it to you, if required. Again thanks for the incredible performance!

A lot of practical information in this one, Kevin. As usual. Thank you very much.

I really enjoy your videos, and I'm learning from you every time I watch one. One of the things I like best is the unpretentious style you teach with. Thank you for what you do.

I know you like your way of sharpening things And that's great// this is a suggestion try diamond lapidary disk My set Goes From 60 80 240 600 800 1200 3000. The 3000 disk We'll take off hair next to skin but will not cut standing hair If I want it sharper To cut standing hair I use a leather disk charged with something like jewelers rouge. I've always liked your videos I wanna thank you for all the information you've given everyone Keep up the good work

Thanks for showing us that. I love a really sharp chisel.

About 2 years ago, I got tired of dull kitchen knives and my wife complaining and buying something cheap. 1st bought a water type stone, (400/1000), and it was some better but very long time to sharpen 12-15 knives. 6 months later I bought a Tormek Bushcraft T-4, which has an 8 inch wheel instead of a 10 inch wheel. Then bought multiple jigs, long blade, medium, pocket knife and chisel. I am considering buying the 1200 grit diamond wheel because they say you don't have to "true" it. (We will see). But the biggest advantage to that wheel that I see, is they make a guide where you can also use the side of the wheel, without danger of the grinding stone exploding. I don't have a high speed grinder yet, but when I do, Tormek makes a guide you can mount to the grinder. Just bought a drill press today, (hooray), and will use your buffing wheel/rouge trick. Thank you as always.

love the drill press buffing idea

Thank you, there may yet be hope for some of my chisels and planes.

This is definitely something I need to get better on it's sharpening tools

instead of these buffing wheels, I think you rather get a hard felt lap.

If only your video focus was as sharp as your equipment :)

?! Exactly what is "a Flattener" [time 5:09] ?!?
