I'm having a hard time keeping a sharp point on the tip of my knife when I sharpen. I seem to get to much of a rounded tip. The edge is very sharp up to the tip. I use more of a sweeping motion when I sharpen as oppose to a push and pull, if that makes sense or helps. What am I doing wrong or is there a technique or trick to use? I like a nice "point" on my knives.

Picture, please?!?!

I'd guess you're over grinding it.....spending too much time on such a thin section of the knife.

Sounds like you are just going past the tip. Try not lifting the handle so high or sweep past the tip so far.

These are from 3 different knives, all Victorinox. My points tend to be too rounded.
You can tap pretty hard on the points with little pain and no cuts.
This is why I have yet to buy an expensive J-knife, I want be competent with my sharpening first.

It almost seems like you are going past the curve of the edge but something tells me your just not defining it enough in the grinding stages.

After another look it appears you are shy of the tip, look at the 3rd picture down and you can see the grind marks stop a few mm short of the tip.

I don't have the experience these other guys have, but that's what my tips used to look like and it's because (as Jason said) I wasn't grinding all the way to the tip. I needed to lift the handle more and rotate the blade more as I rounded the curve to the tip (as per Ken's video). The 3rd, 4th, 5th, and 6th pictures all show the primary ground closer to the edge at the tip (i.e. narrower bevel) than the at other points. My knives look like that when I'm not grinding all the way to the tip (or just not spending enough time there).

Thanks guys. I'll try to pay special attention to the tip when setting the bevel and follow through just a little more if needed and see how it works. If I keep having trouble I'll post more(and better) pictures until you guys get me straightened out!

Exactly that the other guys said! The 2nd pic shows that you aren't sharpening to the tip fully. Try a coarser stone, but watch the angles and don't go too far!
