Steel - 440a
Pressure used approx 1-2 pounds
Stone used -
Suehiro Cerax 700 grit
Dlt strop with white compound
I had already done a small amount of sharpening before starting this video. I wanted to verify the steel was actually 440a, since there were so many conflicting reports. Based on the 'gummy' nature of it, I would see no reason to argue it isn't. Also, i added a sharpening notch, which at the end, I found was not deep enough.
440a, for me, is terribly difficult to sharpen. It grinds super fast, and creates a burr quickly. I tried some high angle passes, with ultra light pressure, to aid in burr removal. The tip was never fully apexed in one area, and can be seen when I show a close up. Light reflecting can be clearly seen. Regardless, the edge is much better now, than when I received the knife.
I am going to keep the edge at a lower grit, for that toothy feel. Also because, 440a doesn't perform well polished. At least in my experience. I usually go full convex with this steel, and others like Aus6. Convexed, they seem to have better edge retention, and are easy to strop back to sharp. Time will tell how this one behaves
I created this video with the TH-cam Video Editor ( / editor )
On 1 of the edge trailing strokes on the water stone I thought I actually heard a piece of the burr break off. First time I've ever noticed that in sharpening video. Enjoyed the vid, good job.
Yup. If you listen, just before I said I heard a piece break off, it's there as well. Doesn't always happen, but this stuff forms such a large burr when sharpened, it lets you know. Cheers
and 440c perform well with high grit or is better in lower grit?
I have used it both ways, and it does fine polished. Is it better on a lower grit vs a higher? For my cutting tasks , yes, but it doesn't hold onto that sharpness long.
To clarify a bit more, there are only a handful of steels that I do not like to polish fully. Aus6, 440a, 440b and perhaps a few others I can not think of, off the top of my head. They do seem to hold a polished edge a bit longer than a toothy edge, esp when cutting softer materials, but I find the aggression on them desirable. Like all things, you have to find what works for you.
Thx for clarify
Hi , what is your experience with sharpening the MIKOV PREDATOR but N690 steel blade ?
haven't had the pleasure of sharpening one yet
Wait until you try to sharpen the RWL34 version. That one's a bitch.
👍👍👍
👊
Ohhhh friend, you ruined the style of the Mikov Predator, dagger-style, not knife-style, they look horrible like that (obvious to my personal taste)
😂 yea the single edge isn’t exactly pretty. Still, dagger style makes a poor edc, imo.
@@JefIn the end, I transformed my predator into one similar to yours, it didn't turn out as good because the sharpener doesn't have much experience sharpening and I lost about half a centimeter of blade but it turned out sharper than the factory.
Have you ever, sharpen crappie Chinese steel. Shit steel and it cracks on diamond but on water stones it does better. It's f××king hard, one side never stays sharp or cracks.
I have sharpened steel that just dissolves, when you apex it. The edge crumbles away. I don't think I have tried switching between diamonds and water stones with it, however. I can tell you, the butter knife challenge I did, was a similar steel. I was able to convex it on water stones fairly well, but when I went back after recording, and tried to create a keen apex, it crumbled away.
