HA! About a week ago I was literally looking at these knives and was wondering how the diamond films would work on them. It was quite a tricky sharpening with missing that (truly) micro bevel. I wonder if that is part of why people have trouble at the start and just don't give it enough time.
For people reading the comments: The edge leading vs trailing argument is that edge leading is more aggressive and could make a toothier edge (micro chipping) and edge trailing leaves a smoother edge which is better for the finer grits. It is easier to see in low grit diamond plate sharpening. You don't want to go anywhere near that low in grit with these blades however, it would cause a lot of chipping. It would be neat to see the stages of progression under the microscope with leading vs trailing stokes only.
Another difference between the Edge Pro films and the States LLC films is that the EP ones are aluminum oxide and States are diamond which really helps with this material. Also, with the tariff on stuff from Russia, the Venev Orion stones are currently about $100 more than the Matrix stones, when the Venevs used to be ~$70 cheaper for the 6 stone sets. Should end up with a lot of people going the Matrix route for a while.
Very astute...
- EP films are crap (cut easy and not diamond)
- Orion / Veneve stone were $30- $37 each prior to the Russian conflict now they are as expensive as the EP because of limited supply. The price will come down when things return to normal. (I talked to Gritomatic at Blade Show)
- Sandrin knives are not hard to profile \ sharpen in terms of material removal. Something else is going on.
- The answer to what is going on might be answered if we had an image of a factory sharpened edge under a MICROSCOPE. (Lab grade super high resolution) Then take a user sharpened edge and compare.
THANK YOU FOR WATCHING \ COMMENTING : )
Were is the cut test? You left me hanging. Please show the knife cutting. Thank you.
Joe, at this point the knife only has a "Working Edge" level of sharpness.
I am going to get the edge "shaving sharp" Then send it to Outpost76 for cut testing. (I might re-post to my channel) I will have a new sharpening video of the Torino. Stay tuned and thanks for the comment \ sub.
prob not going to be to useful, but i grind carbide endmills, to manufacture them we use a diamond wheel running at 3000+ surface feet with wheels as low as 80grit, up to 400 for a standard finish, for nicer finishes we will rough with the lower grit wheel than come in with 800+ grit running at as fast as the wheel (or machine) will run.
I am going to take another stab at using my diamond stones and a microscope to get the edge sharper. If this fails grinding is the next experiment. Thank you for the help. : )
Are your lapping films diamond lapping films? Else this might be a problem. Stropping with diamond emulsion on a flat piece of aluminum might improve the edge. Machinists lap their tungsten carbide tools this way
The lapping films are diamond... Thank you for watching : )
@@barkingspider2007 But the backing?
How have things been? I just thought of this video and was wondering if you had any luck getting a great edge. I was following the Blade Forums post then things just seemed to die off. Guessing life came in and started swinging.
I have shot the follow up video..
Needs to be edited. Deer Hunting season is going on...
Peak rut right now 😎👍
Thanks for watching!
@@barkingspider2007 Hah, I know that all too well, got a whitetail hanging in the shed right now.
@@Riyame I am also thinking about buying a Bess sharpness tester.
The key to knowing for certain how well the edge is doing ($189) Yikes...
