    Default 1/4 vs 1/2 hollow

    I'm getting ready to order a Koraat custom and have all but one of the design details figured out - the grind.

    I prefer the wedge grinds, but I have and like a 1/2 hollow.

    I'm beginning to get good edges on hollow grinds, but haven't figured out wedges yet. This razor will eventually go to my son, so I'd like to get a hollow grind for ease of maintenance.

    I've never used/honed a 1/4 hollow. Do they hone up like other hollows or are they more challenging like wedges?

    JJ-A beefy, shoulderless quarter hollow is probably my favorite grind, and they can take as good an edge as any. I don't always get on with the real singing full hollows-they often seem too "scrapey" for me if that makes sense. I'll scrounge up a pic or two front-wise of a couple of them. I love the heft!

    I have problems honing wedges because there's nowhere for the sides of the tape to hide from the stone. Does the edge of the tape contact the stone on a 1/4 grind?

    I agree with you about the super thin grinds being "scrapey". I've gotten some really nice shaves from them, but the sound always bugs me. I prefer the silent whisker assassins. Once I figure out honing the wedges a lot of my hollows will probably start leaving the rotation.

    For what it's worth I always have on at least 1 layer of tape, some times more with a real "wedgy" blade. I dont' own a Koraat (though I've heard great things!). I stupidly sold this nice Friedmann and Lauterjung's Celebrated, but I would call it "quarter hollow."

    Here's a link to the grind image at Koraat. http://www.koraat-knives.at/konfigbi...indoptions.jpg The 1/4 grind is the third from the right.

    You won’t have any issues with tape contacting the hone on the blade face, even with a near wedge grind that is in that link above. Honing a wedge isn’t any more difficult than a full hollow grind. It’s when the heavier ground blades have had a bunch of prior honing or abuse and the bevels get really tall that it takes a while to reset a bevel. I would get exactly what you want and not worry about future honing.

    No matter the grind it’s all about the bevel set. Worn wedges and 1/4 hollows take more time and technique.
    I would base your purchase based on your shaving preferences. Personally I find the 1/2 hollow to be the preferred middle ground. They are easier to learn than an extra hollow or a wedge or 1/4 hollow. They will all shave as well as they are honed. But what you like is not so easily defined.

    I get you Rez, good point.

    This will only be my 2nd new purchased razor (first was a gift that got me into straights in the first place). So some of my troubles with honing wedges may be the spine wear, etc. I really like the wedges I've gotten from Boushie and have good shaves from a 1/2 hollow I honed, so I think the 1/4 wedge might be a nice middle ground. Plus, I haven't tried one, so I'm looking forward to the 1/4.

    Get what you what. Being a new blade honing isnt going to be as much of trouble as grinding now has come a long way. I vote for 1/2 but its not my money or face.
