    Hey.

    What do you use to realign your edges? I read people use ceramic and steel rods, some like to strop on bare leather and some swear on fine whetstones for this task.
    For a home cook like me, does it even matter? Are the differencies so subtle that it takes a long time pro to tell which end result is better?

    I have white ceramic (MAC I believe, 1200 grit?) rod, old leather belt and this self made borosilicate glass rod which I longitudially grooved with 170 grit wet-sandpaper. Can't really tell the difference of the end result, but I noticed that glassrod doesn't remove much, if at all, metal. At least in comparison to white ceramic rod which gets black after few knives. That's why I most often choose to use borosilicate. My knives are rockwell 55-61.

    Any opinions one way or another? Also interested whether I should use more fine/coarse grit to groove glassrod instead of 170? And are steel rods more ideal to western knifes them being softer metal?

    Thats a large range of hardness. I only use stones on knives 59+.

    Harder steels dont need edge realignment. They are either good or they need sharpening.

    I steel my knives of all origins. I find that the steel works even with knives that are harder than the steel itself.

    I only use stones to sharpen, and only use strops after the stones.

    Ceramic rod sharpens a little and I only use that when I'm too lazy to do proper sharpening.

    You won't find knives as hard as steels. Even the simplest one has an chromium layer by galvanisation.

    I dunno, just that my steel says it's HRC 61.

    Strange, had something in the 70's in mind. Anyway, I don't like traditional steeling very much. It's rebuilding an edge out of material that has failed. Better remove that fatigued steel by abrading.

    Here is some data on hardness. (I keep seeking more of this kind of real testing to supplement the specs and internet chatter about hardness or "bad heat treatment" but never find any.)

    http://www.cookingforengineers.com/article/187/Knife-and-Sharpening-Steel-Hardness

    I once was an ardent steeler -- German/French stainless steel knives and American/French carbon steel knives using a ribbed German steel -- but gave that up for a ceramic hone and a smooth steel. But when the ceramic hone doesn't do enough "touch up" then its immediately to stones.

    The numbers for hrc shown in the link taken as a whole don't make sense, especially the 20 point difference for the two 4 star sabs. Knives are very difficult to measure because of surface irregularities and thinness making it difficult to positively anchor so there is no flexing or other movement when the point bears down. A proper test would have the knives potted in a hard wax or low-temp alloy like ceramet, and I don't believe that was done here, nor many points taken along the length and breadth of the blade, which can vary considerably. I wouldn't trust those number, though the higher ones are going to be close, movement here will show up as a lower than actual hrc.

    The sharpening steels are likely all over 62hrc, though certainly not as high or higher than 70 which is file hardness and about the practical limit of ordinary high carbon carbon steels.

    I dunno Rick. All I know is that it’s the only data out there. There must be more data somewhere.

    But the 14-inch does look like a statistical outlayer for whatever reason.

    Oh and as far as steels go, Benuser talked a lot of us away from steels and to stropping on stones instead, and I for one have never looked back since.

    Similar to brianshaw, I only use super fine or completely smooth steel. No groove-y stuff.

    I'm getting feeling that you guys use knife quite a lot daily. For me it's like 15-30 mins every day or every other day. So I propably don't have to worry about honing too much. Although I have to say that knife feels sharper after few light strokes on glassrod (vg 10 cleaver).

    I read that thread where stone stropping was discussed and going to try that as well.

    About that couple questions popped in mind:

    1: Which leaves better edge for veggies, Shapton Pro 2k or 5k? And do I need to strop on top of it? Got synthetic pad and chromium oxide powder (1 micron?) to go with it for that purpose.

    2: When stropping on stone, how many swipes average you feel you need for regaining the edge? Or do you test on paper after every few swipes or something?

    Sorry for all them Q's , but I'm trying to find that critical line where basic knowledge turns into hi-end stuff which only helps you marginally forward anymore. Not that I wouldn't care about it, I'm just not that far yet.

    Chefross : That DM stell seems so nice. Maybe some day :)

    I try to revive the edge on the finest stone. When two strokes per side aren't enough I go to the coarser one. You may feel when stropping whether the edge is smooth again, or verify with your nail along the edge. First read my general disclaimer.

    Don't forget to deburr after stropping. Especially with VG-10, which is likely to develop a wire edge, a burr on top of the edge. Crazy sharp, but failing after a few cuts.

    Would cork of the winebottle do the trick, or do you mean stone? (deburr)

    Deburr on a stone by very light longitudinal strokes. A winecork will help in reducing a carbon burr. VG-10 burrs won't come off. Or leave a destroyed edge.

    The bane of my life indeed. I find that it happens more with AUS-8.

    I usually strop repeatedly trying to get rid of it out of anger, and ended up with a not so sharp knife that had to be sharpen again. And the loop of frustration continues...

    Jig user?
    I ask because the slight variation in angle that occurs with hand sharpening makes the building up of a wire edge less likely.
