I know how to sharpen, I know this is not a comment to denigrate my skills or anything, but I won't talk about damage if it is due to me not being able to reach an apex or reduce then get rid of the burr ^^. I use venev Cerberus Dog and venev Pegasus stones. I have a WS Precision Adjust that I modded for stability (no movement of the clamp anymore) and being able to use the Cerberus Dog stones on. I reprofile with this and sharpen freehand (until I someday might have to reprofile).Traditional.Sharpening wrote: ↑Sat Aug 05, 2023 6:37 amI would expect that this has the potential to be related to how you are sharpening. Can you describe to me your sharpening tools and how you grind the edge with those?Ramonade wrote: ↑Sat Aug 05, 2023 4:32 amDang, I had written a big reply detailing everything yesterday and sent it. Apparently it did not go through...Traditional.Sharpening wrote: ↑Fri Aug 04, 2023 7:41 amI would want to resharpen and repeat that several times to be confident that what you are seeing is not a result of damaged steel in the coarse of processing/production. Did that edge shave arm hair easily in both directions when you had determined it was burr free?
I haven't had my coffee so I won't be as long this time .
The short answer is yes, it actually split hair in 3 length-wise which is usually what I aim for. I rarely go very in grit, this was a F400 edge. I sharpened it twice since then and will keep using it for the same tasks, time will tell.
And yeah I encountered this kind of situation with Seki's K390 twice, and other steels too. I'm just really unfamiliar with 4V. I only had one knife in it a month ago (3 now), from kizer. And it can handle pretty much everything.
The feedback on the stones feels like the same between that kizer and the Goddard, so the HT aren't too far apart. I sharpen a lot since it is my favorite dimension of this hobby. High carbide steels with poor HT have a way of telling you their life is miserable once you hit the stone with the blade
I don't really get what you mean by "how you grind the edge" ? If I'm sharpening I simply hit the whole bevel on every pass. I check every few passes, or sometimes even each pass, to see what I'm doing.
Low pressure since the start, reducing burr before getting to the next stone. I can usually cleanly cut toilet paper after my first stone. This 4V wasn't an exception (well, with an F80 edge it's not as clean of a cut, butit helps me attest that my apex is good).
Usual progression is F80 / F150 / F240. I went farther with this 4V to see how it would behave (F400). Then after the final stone I go to my strops which are hard leather with good backing, minimal pressure is used for a couple of passes on the 3 microns, then 1 micron then 0.25 micron Gunny Juice.
After the first reprofiling/sharpening I did cut cardboard, wood and other stuff to see after each cut if an imperceptible burr did not stay (it rarely does).
I have a jeweler's loupe and other gear to use if I ever have trouble on a particular blade.
