    Heiji geometry

    I finally got my hands on a Heiji ss gyuto and was suprised by just how asymmetrical the grind is. For some reason i was expecting it to be closer to 50/50 than this.

    Is this the normal grind for Heiji? The reason why i ask is because that shorter, sticky out heel to tip secondary bevel looks like a wedge waiting to happan. To me that left hand bevel looks like it could do with a touch of thinning, particularly at the belly and tip.

    I should point out that i haven't used the knife yet, so i could be worried about nothing.

    These pics don't show the true extent of the "wedgeness" of the left hand bevel, but it's the best i could do with faiding light.

    It looks like other Heijis I've seen. The answer to thinning will likely become evident through use.

    That's more asymmetric than any of mine. I would use it first before worrying.

    Yeah. Use it. I thought the same thing when I first saw them. I had to borrow one first to be convinced they deserved a spot in my block.

    I find Heijis to be wedgies, pretty bad, really, but in all other aspects they are wonderful.

    In your experience, when have the Heijis you've used/owned wedged?

    I just used a Heiji for the first time this past weekend. I was impressed. The geometry of a Heiji is special.

    It looks like the center of the blade is hollow ground...and while it does seem a little thick 1cm or so above the edge, in use that probably wouldn't be an issue. Maybe in an actual true push cut it could wedge, but I think with even a slight forward or drawing motion the wedging could be negated.

    Interesting grind.
    I try to be the man I am..in times of broken lives. Shattered dreams and plans..standing up to fight. Pressures and demands..staring at the knife. Holding in your hands..

    I find that for cutting thin slices off of anything they can't be beat, but I also find that in a thick carrot, a daikon or anything else had they take a lot more pressure to get through and create cracking nearly every time. Sure, I can mitigate it by changing the way I cut a little, but that isn't appealing to me.

    Mine performed well for most tasks except chopping, where it seemed to wedge a bit.
