Re: Community Sharpening Journal
On a separate note - has anyone else noticed that BD1N responds extremely well to a butcher’s steel? I sharpened my z-cut a couple of days back and got it to hair popping sharp using my usual gear and strops. The next day it got some heavy use so I thought I’d give it a quick touch up on my butcher...

Re: Community Sharpening Journal
Helped teach a freehand knife sharpening class over the weekend. Been teaching freehand knife sharpening for 7 years now. I enjoy taking a rather complicated subject and simplifying it into something entry level that could be understood and that gives excellent results. https://i.imgur.com/Lr6Gugg.j...

Re: HRC Database
There are many different ways to get the same hardness but not all are equal because the hardness is only measuring the sum of the constituents in the microstructure not the individual components that contribute the most to strength or toughness or the lack thereof. A great example is work that was ...

Re: What do you want to see at Shot Show 2024?
When you guys are talking about new designs, is there anything specifically about a design you guys are looking or hoping for?
Something practical? Something eccentric?

Re: Community Sharpening Journal
Finished grinding and sharpening more CATRA blades for Dr Larrin, also some metallography. Looking forward to seeing his article about it. There you go again being a bad influence.

the high toughness of AlOx, can also be a downfall because it will not break down and self-sharpen with use. AlOx simply goes to dull which further decreasing cutting performance. Dude! This post is particularly timely. Last night I was flattening/restoring some stones, and was pondering my Sharpma...
