Rounded the tip off...

[bgentry]

I watched your video...21min,15 sec and you accidentally cut off half of it.

I was filming with a DSLR that has a time limit. It's something like 11 or 12 minutes (it's based on file size so it's not a fixed number). I think I missed around 5 to 7 minutes of sharpening. I assure you it wasn't any more exciting than the rest of the video.

I'm going to go with your #6 speed locked on and set it up high on a table like you did. It looks like it works out much better than my one handed pull across technique.

These days I'm less patient. I crank the speed to almost full for most of the low grit grinding, which is the majority. For finishing, I lower the speed down to 4 or even 2. But I've also found that I tend to make big nasty burrs with the WSKO and I like doing a final finishing step on the SharpMaker or other manual system. That insures that I really remove the burr properly, which is hard to do on a grinder. If I had a buffing wheel it would be different. Just with belts it's pretty tough to remove the burr correctly.

Good luck!

Brian.

Thanks Brian. I'm not sure what speed i used before when damaging the cutting edge, so I'll have to be more careful this time. My green stropping compound on balsa wood polishes edges so they're pretty shiny, but I still have a tough time getting my blades to slice paper smoothly and quickly. Maybe the low speed finishing belts will get me there, and i can remove the final burr with the balsa strop.

Hi there I am new to this forum .
I have been using the ken onion worksharp with bga with good results. The only downside is that my knives with pointy tips usually have their tips rounded a little bit by the belts.

I move the edge till the tip is half way across the belt and lift it off .I have never let the blade slide off the belt .however my tips are still being rounded off for almost all my blades .I have tried with varying pressure or speed settings but am still facing this problem. I worked around this by stopping short of the tip when sharpening on the system .as I needed to slow the blade as it reached the tip, I end up grinding the portion of the blade near the tip slightly more than the rest of the blade .Not really a solution .

I have resorted to just pulling the knife through to the middle of the belt and grinding down the blade from the spine to restore the tip .

Any one else is observing this ?

Another issue I notice is that the bevel length is usually longer on one side of the blade compared to another (right side). I speculate that the right side needs to be ground by lefties. Most folks are right handers so when grinding the knife the side ground by the left hand is often at a steeper angle . (Referring to the factory profile). I noticed this difference in bevel on zt and spyderco knives. Another explanation is that this is user error however between every pass I place the blade face back on the guide on the bga to check my angles. On some blades I had to grind one side twice as much as the other to correct this a little.

Any one else face this ?

Thank you for your patience on reading this

I have also noticed with my Mk2 that the bevel length is higher on the right side of the sharpner. I've often had to lift the blade when sharpening to get more of an even cut on both sides. It annoys the heck out of me. Fortunately, I've remedied the issue with rounded tips by lifting the blade slightly up before the tip hits the belt, and letting the trigger go when the tip is at the halfway mark of the blade tip. I do however have some issues getting the blade tip sharpened the way I want it sometimes. Don't get me wrong, I love the machine, and I have gotten spectacular results with other knives, I just have that tip issue once in a while.
