hey guys i just bought an accusharp to sharpen my hanwei dadao...i read that any idiot can sharpen a sword with this thing but i guess im not just any idiot. i was sharpening my sword with it and now the edge looks all wavey and un-even.
did i not sharpen long enough? did i push down too hard? did i not push down hard enough? any ideas would be helpful ill probably continue to sharpen it later and not put as much pressure down on it.

uh-oh... Accusharps are known for ripping up and edge realy badly- they tear metal from the edge, and quite a lot of it relative to other sharpening methods. The best suggestion I can give is to not use an Accusharp at all on a sword- they are meant for sharpening much shorter knife blades. Gimmie a sec and I'll post some invaluable sharpening links... edit/add: K, here's the link to SBG home page sharpening tutorials: www.sword-buyers-guide.com/sharpen-a-sword.htmlThat's Tom K. in the video and he's THE MAN TO ASK about sharpening on this forum- he's helped me a ton  Here's a link to a thread he posted with the same vids and an update vid on his improved method: viewtopic.php?f=18&t=84If you simply don't want to use anything else besides the accusharp, and I still can't convince you to even use some sandpaper to clean up the edge- then use a very light touch with your Accusharp and practice, preferably on a SLO first. You will have to remove more steel now to fix the wavy edge, how you choose to do this is ultimately up to you. Any chance for pictures? that would go a long way in figuring out what the best step is now.. |

I only use it on cheaper swords, and only if they come very very blunt.
I usually use the "scary sharp" method.

damn well thanks for the replys....i dont think i will use the accusharp again. i will put up some pictures within a few days. its pretty bad its wavy down the whole edge and also the secondary bevel is not symmetrical its like twice as big on one side as on the other.

Makes a large secondary bevel, geometry is destroyed.

Not neccesarily, it makes a great starting point for an apple seed bevel from a diamond shape.

You can fix it, no worries! You might need to begin with filing the majority of the secondary bevel out before sanding- as described in Toms first video. If you do opt for filing make sure to get a good file. How do you know it's a good file? Buy a name brand and don't but the least expensive one you can find.

OK I'm sure you read the accusharp thing.... HERE Its actually a sticky post in this section of our forum (just a FYI that it came from the new website) viewtopic.php?f=32&t=29Section 2.4 Along with the accursharp thing you saw www.sword-buyers-guide.com/sharp ... words.html And the above posted Sword Sharpening tutorial, there was also this one. www.sword-buyers-guide.com/sharpen-swords.htmlHowever if you'll notice in that Accusharp tutorial, it sugests that your problem may be 1 of 2 things.... Too much pressure, or not enough practice.... and the video compnent sugested it takes about 10-20 Min (Per side) Maybe that helps.. maybe not. But as an FYI to everyone, he did find that info here. |

ok here are a few pics of how the blade looks now, the wavey pattern runs down the entire edge. notice how the bevel is more prominent on one side of the edge as on the other. maybe i was holding the accusharp crookedly? i dunno but do you guys think i should try to continue with the accusharp? i prbably did atleast a good 15-20 minutes on it... or should i just grow a pair and learn how to sharpen it the old fashon way? |

Stoski, it looks to me like you weren't applying enough pressure evenly. I'd try a some more with the accusharp. Then move on to stones and sandpaper.
I've used an accusharp type thingie before and it makes a mess but it can be fixed. I won't use one again, it's just better to do it the long way or better still use a 1x30 belt sander like in Tom's tutorial.
Don''t get too down about it, it's all a learning process.

ouch!
I love my Accusharp, for sharpening unedged objects and such, but it really hurts to see what it will do to a sword. :shock:

judging by the pics...man o man... u def used WAY to much pressure and it would appear so much in fact that it like jerked and skipped as you did it...if u must use these things u need to start near the guard and in one machine like smooth motion go allll the way to the tip in one motion and u need to count how many times you did it and make sure to do it that many times on the other side...u also need VERY LITTLE pressure just the weight of your hand is enough and make a couple passes checking your progress aftyer each until desireable! hope that helps.. (thois is on a fresh edge though... urs is now pretty messed up so i dont think ull fix it with the acusharp ull need to file it smooth and then follow the steps above from a fresh slate!)

I hear ya man, I know Accusharp is mentioned on the SBG links etc.--- but i'm not sure it should be. Not at least without a bigger disclaimer about possible damage and maybe pictures- like the OP's pics- to show how it can go wrong. just MHO.

I do use an accusharp on knives, but that's it. You used way too much pressure, and a hesitant motion. That edge is going to need filed out until you have an even edge again. Watch Ton K's vids until you're dreaming them, and follow his advice. Also, remember when filing - file in a single direction when using a hand file, if you try using a back and forth motion with the file (unless you've had practice at doing this) you can make the blade even more uneven. Slow and careful is the key here.

yup. I must have watched his videos a dozen times before I first practiced on my junk SLO's. Then watched some more. then had them on when I started on the real deal.

Best is to sharpen it the old fashioned way, what you have can be easily fixed with a good ol grinding stone.

Stoski, i usually prefer a good ole fashion draw file followed up by sanding block with varied degrees of emery cloth. i end up with about 1200 grit tho you can go higher if you have the patience and arm left. some of the guys do use belt sanders, but i dont since i am afraid of overheating. the machine takes more practiced skill since a mistake can happen quicker.
also, i would like to ask just why you wanted to sharpen this blade in the first place. mine came quite sharp from the box. remember if it is sharp enough to shave you, then it will lose an edge quick.
