Thread: not holding an edge

  1. #11
    Thanks everyone. I think its my fault. I love the "edge" after I just sharpened and then as I start to get through the food during the week, I notice a slight change in the feel

    they are defiantly still very sharp, I just want them to feel as sharp after I sharpen them.........I'm sure everyone feels the same. Oh well, just have to wait for someone to make a knife that stays sharp forever

    If you don't have a strop, try stropping on newspaper. It works surprisingly well to help the edge feel closer to fresh after some use.

    Globals lose their initial "fresh sharpened" feeling very quickly in my experience. I still own three Globals, and use two somewhat regularly.

    Also, what grit are you going up to? I've felt no need to go above 1000 (now 2000 after getting Jon's Gesshin 2000 stone) because going up higher in grit that than is not worth the time and effort - you may lose that "fresh sharpened" feeling in a day. A microbevel certainly can help, but I almost never do.

    Get a bottle of something in the 1 micron range from Advanced Abrasives. You can then just spray it on whatever you want to strop on and you're set for life. If you strop right before use you'll be good for maybe months before you need to reset the bevel.

    i use my knives a lot, and i am able to maintain edges for long periods using a strop (i usually use .5 CrO on balsa, myself), and rarely actually have to take an edge to the stones (and when i do, it's almost always just a few passes on the Kitayama or a fine natural [this is after i have it set up how i want it, of course]). i use almost all hard carbon, but it shouldn't be too much different with decent stainless.

    With the carbides of these stainless it might be a little different. Not so finely grained as some carbons. Stropping on newspaper with a lot of black ink will do a lot, though. It has to be in the 1-2 micron area.

    Ahh Globals. I have a couple that my wife uses and my inlaws have a huge set that I sharpen occasionally.

    First off, they get an absolute b@$tard of a wire edge. After my 2k stone I literally drag the edge down the wooden handle of my strop to rip it off (you can see a little pile of metal left in the wood) I then do another round on the 2k with gentle pressure, 4k, then strop. I've tried higher grit but it doesn't seem to make much difference.

    The other thing with globals is that, as has been mentioned, they lose that initial "fall through hanging paper" edge in like one to two meals worth of use. They keep a "good" edge for a really long time but "screaming" edges are very short lived. More obtuse sharpening angles help, but the issue seems to be more with the steel.

    I haven't chimed in yet just because I have been testing my edges. I have finally been able to shave hair on my arm with my Globals. I only have 2 stones atm, a 1k King Deluxe, and a 600/4k combo Samurai.

    After my first sharpening of the 3 knives I wasn't happy with what I achieved. They had a edge but they were not what I like for a edge. So I started over again. I couldn't feel any burr forming at all, but just did touch up on the 600 stone. Then on to the 1k, still no noticeable burr but still a edge. Then the 4k with heavy pressure, the stone made some swarf so I knew it was cutting but nothing noticeable except a shinier bevel.

    I then stropped on leather. I used to use telephone book pages but it took quite a while for a noticeable change. I can now get a screaming sharp edge, but it wont last very long at all. I will just strop again to get it were I like it. Also the hrc on Globals is 56-58, which is why (I can be wrong here so please let me know) it wont hold a "screaming" edge for long.

    Also I have noticed that a weird angle is needed to get there. Almost a 45 degree angle or higher.

    My Globals respond very well on leather + Cr2O3 at an angle of 25 degree inclusive. That 45 degree is a microbevel I guess?
