I'm not the best with words in moments like this. Vadim passed recently due to heart failure. I just find out myself.
Vadim? Or Valdim? Either way, my condolences.I'm not the best with words in moments like this. Vadim passed recently due to heart failure. I just find out myself.
Yes...As in Dr Kraichuk?

@Deadboxhero posted an excellent thread about the loss on the Spyderco forum:

Not a problem! Glad it helped. I learned a lot here as well. In fact the last of my supplies came yesterday for adapting his method to home sharpening. On my first test I was able to get konosuke HD2 steel to an estimated 50 - 100 BESS, which is insane compared to what I was able to do entirely freehand. This was done without using any traditional deburring technique at all. Instead a used -.1 angle grinding. Visual tests and edge degradation tests all indicate there is no feather / wire / foil burr. More tests to come!
The entirety of the blade length was able to achieve quite smooth against the grain hair shaving. I was able to cut a free hanging hair along portions of the blade . My estimate should probably be revised to a BESS between 50 - 150. I don't have immediate plans to buy a BESS machine so estimates will have to do for now.
Here is the script if anyone is interested:
#This is your desired angle, change as needed
$TargetAngle = 15
$TargetRadians = $TAngle * ([Math]:i / 180)
#This is the 'length' of the blade from the spine to edge at the point you will be measuring the height of the blade off the stone. Change this to the measurement taken after the jig is attached.
$Bladelength = 45.13
$RequiredHeight = [Math]::Sin($TRadians) * $Blength
Write-Output "Blade length : $Bladelength mm`nDesired Angle: $TargetAngle degrees`nNecessary blade height from stone top is $([math]::round($RequiredHeight, 3)) mm"
This is going to be blasphemy to our skilled free hand folks but using a jig to remove the human element of wobble allows you to focus solely on pressure and vertical height adjustment to compensate for blade belly and I really recommend it. Not perfect for all applications but you can get angle consistency on par with a highly experienced sharpener without spending years training your body into a human jig.
I usually tell people to enter "50 sin(12 degrees)" into google search if they want to get the height of the spine off the stone for a 50mm tall knife and a 12 degree angle.
Also, idk if anyone thinks it's blasphemy. It's just not so clear that this kind of fine angle control makes a massive difference for kitchen use once you have some experience, and it requires more setup, so it's slower. I think it's cool that you're doing this, though. I'll be reading your results!
