Work sharp blade grinder tips

Hi All
New to the forum. Hoping for a little advice for something that's been bothering me for a bit now. I've had a work sharp ken onion ,with blade grinder attachment for 3 ish years now. Absolutely love the tool or I should say the blade grinder portion. So I'm pretty familiar with it and get excellent results for me. But something that's always bothered me is I always seem to lose the factory super pointy tip that comes on my knives. Not that I'm getting a rounded tip of a dull tip, just that I seem to lose that super pointy (sticky?) tip that comes on factory knives. I've tried all kinds of various ways to adjust the way I sharpen like having the tip 45,90, parallel to the belt, but can't ever get it quite right. Closest I come to a super pointy tip is having the tip parallel to the belt, but then I get a wacky looking grind at that spot. I've been experimenting with just at the very end of the grind trying to move the tip parallel quickly and then removing from belt, that seems hit or miss. Any advise on this? I just got a shaman and now a pm2 on the way and don't want to ruin the really nice factory tips. I do have a set of diamond bench stones, but prefer to save as much time possible sharpening and would rather learn how to properly use the blade grinder. I get plenty time on the stones with my chisels and plane irons.

Thanks
 
You are probably pushing too much on the belt. I had the same problem and used few non-important, old knives to learn how to do it.
Pressure on the belt should be minimal at the tip, and you need to pull the blade faster than when you grind/sharpen the bevel.
It is a matter of getting used to it. It is a well designed attachment but there is no hard support under the belt and this causes the belt to give up under the smaller surface of the tip,
when you moving it across. That's why it rounds the tip of your blade. I found the solution in my case is to move across fast and with minimal pressure,
maybe with few more repetitions than when I'm sharpening the main bevel.
It is a great tool, I love it and I'm also getting good results, but when it comes to sharpening more valuable knives, I'd never touch it,
I'd go with my Wicked Edge and the results are much better than when I use the grinder.

Thank you. It's got to be a technique issue. Think I'm going to try and just remove the tip as soon as it's fully on the belt and see if that helps. I know that's in the instructions for the regular attachement which I've only used once in my 3 years owning the machine, just figured it didn't apply to the grinder because you can manually angle tip with the grinder attachment.
 
Lift off the blade before the tip is halfway across the belt. And less pressure when coming to the tip, too. I admit I haven't it perfectly down yet. I get no rounded tips, though. But the edge tends to widen just at the tip. I don't like it and am still working on it.
