    Default da

    if you are looking for the sharpness similar to other blades DA will not get there.It will hone ease and as above mentioned some could have uneven back problem.i have personally honed 2 for srp members and shave was ok on both but not great.I did mention to both members about it.You may making mistake and wanted get the edge similar you used to getting from old blades.it will not happen.I think this is the reason .you sharpen the blade on it is maximum potential and it doesn't act how it should be then you still continue hone ended up overhoning.This is 1 possibilitiy.
    Second one are you taping back of the blade?If not you better do so,
    hope this helps

    Thanks for the tips. I didn't realize it might not get as sharp as older (better?) blades. I didn't tape the spine because it was cheap and at first I didn't think I would introduce much if any hone wear since I thought it would come right up like the others I've honed. By the time I realized how much work it was going to be and the hone wear was starting to show, I decided I didn't care since it was so cheap and just kept at it without the tape. If I go at it again, I'm considering taping it and starting at resetting the bevel yet again (it's not set right now anyway, IMO).

    What's funny and ironic is that I actually bought this razor specifically because I thought it would be really easy to hone since it was new, no hone wear, etc. A good "starter" razor to learn to hone on. Boy was I wrong, lol. NOT a good razor to learn to hone on at all, at least not this one.

    Strange. I recently got a DA and had no problems honing it. I'm still pretty new to honing. I've
    only been shaving with a straight since December. I used a Norton 4k/8k and a Chinese 12k. It honed
    up pretty quick. Maybe I got lucky and got one that wasn't far off.

    It seems as sharp as my other blades. My first razor was a DA from Ken at RupRazor which he honed up.
    I used it this morning and got a BBS shave from it. So you should be able to get it plenty sharp.

    update:

    it IS possible to get a DA sharp enough to comfortably shave with. you have to double bevel it. the metal is not of sufficiently robust temper to hold up otherwise. 2-3 layers of 3mil tape should do it. mine are great now.

    however, the shoulder is still a problem. i ground one of 'em off the other day and it was much easier to hone.

    Yeah, the shoulder was a ridiculous PITA for me. I ended up grinding alot of it down the hard way.. using the DMT 1200 mostly, and then finished with the DMT 325 when I got it. I'll try a double bevel and see where I end up. Thanks for the tip.

    I own 8 DA's bought from Stamps222. I like them. I have used them for a number of honing experiments, and they seem to respond well to a wide variety of hones and honing methods. I agree with Sham (hi_bud_gl) that also the capability of the razor is one of the contributing factors to the quality of the edge that can be put on it. But what you describe is not normal. DA's normally hold a very decent shave. If you can't succeed in honing it, there's something seriously wrong.

    Coming of a DMT1200 a razor should shave. Even beard hairs.
    Even after the DMT325, a razor shaves. I haven't tried beard hairs after the 325, but it definitely shaves arm hairs.

    This is not normal. It would be best to check under magnification, to find out if there's nothing wrong with structural intergity of the steel. All DA's I've seen so far had decent steel, but I don't think the manufacturer does much quality control for the price they're sold. Just to say a flawed blade is a possibility.

    I have removed the bevel of all 8 DA's and recut a straight bevel on them, with the use of a DMT 325. On 2 of those, I went to the DMT 600 a little bit too early, and it took me a very long time on the 600 to make up for that. I think on the 1200 it would have taken me even longer. Trying to do neglected work on a hone that's 2 steps too fine, can literally take many hours of honing without success.
    DMT-EE: 3 micron - speed ratio: 1
    DMT-E: 9 micron - speed ratio: 27 (in one [9 micron]³ fit 3X3X3=27 [3 micron]³)
    DMT-F: 25 micron - speed ratio: 512 (in one [24 micron]³ fit 8X8X8=512 [3 micron]³)
    DMT-C: 45 micron - speed ratio: 3375 (in one [45 micron]³ fit 15X15X15=3375 [3 micron]³)

    This overly simplified math shows that a job takes 125 times longer on a DMT-E than on a DMT-C. Stopping one minute to early on the DMT-C takes you over 2 hours on the DMT-E.

    Here's a picture of a W&B I recreated a bevel on last Sunday. Edge was breadknifed, picture shot while honing on the DMT 325.

    Looks good, doesn't it?

    Here's a second picture, aimed directly at the bevel tip (the narrow strip in the middle).

    Clearly still not there. This Wade&Butcher is a wedge. I took me more than 2 additional hours and pressure to complete the bevel on my DMT 325.

    I recommend reading GLen's wiki article about bevel rebuilding.

    Default DAs can take an edge with the best of them!

    DAs are fully capable of getting as great an edge as any other razor out there. It is rather surprising. It may not be as remarkably smooth shaving as some high-zoot Wunderstahl razor that cost $250, and the guys who own $250 Wundersteel razors may not want to admit it, but if you could somehow do a blind shave test, I doubt many could pick the DA out of a lineup in comparrison with 3-4 other full hollow razors out there.

    Here's an edge on one of my DAs, at 200x:


    That's damn sharp and smooth. No taping, no fancy honing required.

    Here's a Sheffield wedge edge 200x:


    One thing you have to be aware of with the DAs is that they are big 7/8 or so full hollow blades, so if you put too much pressure on them when you're honing them, the blade will flex and do wierd things to what you are hoping to accomplish with setting a bevel. They are surprisingly finely ground blades--they flex quite a bit.

    Step #1 when setting a bevel with a DA--don't be afraid! It's a $10 razor, so have at it! That troublesome shoulder everyone talks about? Sure it's there---you can either blast through it with your 1200 DMT, or avoid it altogether by honing with a heel leading stroke at 45 degrees.

    Once the bevel is set they progress quite nicely. The DAs just hone up with no surprises. That's been my experience anyhow.

    I can tell you they hone up more easily than a Friodur does. The Frios can tend to microchip, etc. Here's my latest Frio edge, after wrangling it with all sorts of pleadings. The Frio cost 10x as much as the DA, and was about that much more difficult to hone as well!

    But how well do they keep their edges? Just wondering.
