Hi all

Looking for some advice if possible, have been using the Ken onion WS for a while with great results, switched to the bga for my bigger blades and to get better freehand on it have been doing all my knives on it.

I keep squaring off the tip, an issue I never had with the standard unit (apparently people have this problem and are reccomedned the bga) but I keep doing it. Out of 30 or so knives I've sharpened I have deformed the tip or near the tip on probably 25 of them. Am I being to cautious to rounf the tip that I am actually not grinding that bit away leading to a square? Anyone else have this issue?

Any advice would be great, I have a kme but cba with the time it takes for most my knives only my high end edcs get the 2 hour long mirror polish treatment of the kme

Thanks in adavabce

If you do that you would have to be holding the blade with just one hand. I would not recommend that when using the blade grinding attachment (BGA).
 
I won't argue with that, but I guess you could get a foot-powered switch at Harbor ____ for twelve bucks.
I do NOT have much experience with the BGA, although I've owned it for quite a while. I usually just use the KO...
 
Yeah, you can use a switch, but it would just be a nuisance. Just pull the blade away from the belt when the tip reaches the center of the belt and just leave it running to make your next passes, depending on how many you want to make.
 
It's important not to change the angle when you get to the tip. When the tip gets to the middle of the belt, lift it up off of the belt, don't go off of the edge of the belt.

Pretty hard to tell from the angle it was filmed.

It shows enough to get the point. The part I'm talking about shows him lifting the blade off of the belt rather than sliding it off of the edge of the belt. Not many worksharp attachment videos laying around that conveniently addressing this person's concern

Actually, there are a few. And it is also in the instructions.

I misspoke. That was the video that came to mind and that was the one I looked for. Everyone is more than welcome to provide better videos if they're interested in helping. It's certainly more useful than nitpicking a post that's actually providing content to answer the OP's question.

Not sure, but if I recall correctly, this is what WS's directions for use say.

I do this myself and no square points.

I apologize if I offended you. It wasn't my intention.
 
Thanks for your help guys the trouble is I think I'm doing this there is a clean line on the exact centre of my belts where I never go over so I think it must be my angle instead, do you raise it up slog htly as you get to the belly /tip? I'm not at the moment will send a picture of an example blade when I home

Raising the blade when you get to the tip is how you end up rounding out the tip. If you want to preserve the tip, do not change the angle.
 
If I don't raise it up slightly (not sure if the angle needs to change on the belly and it tapers so do I not need to allow for this to get the same angle) then I'm not hitting the apex at the tip and I'm left with the original grind line on the tip is this just badnluck that my knives came with uneven original grinds and they need to be severely re profiled so guys I'm getting my knives crazy sharp just not the tip and it's bugging me

Watch this video and others if you wish. You can go to YT and watch many videos. You don't want to raise the blade up as you get to the tip, you pull the handle back a little as you go around the curved belly toward the tip, so that the blade edge stays even against the center of the belt. Watch some videos and you'll see how they do it.

Edit: I should mention that you need to always be wary about "reviewers" on YT. Some of them don't even take the time to read the instructions before they make a review. It's pretty sad.
One of them is a popular knife reviewer that couldn't even spend 10 minutes reading the instructions before he started shooting off his mouth. So when you see one of them, stop watching their video. Unless you just want to laugh at how stupid they sound...LOL!

I would add to use light pressure and take a couple of passes stopping before you think you are at the tip, then look at the edge and see what is going on before making it all the way to the point.
