YES it is That Dull.! Brad makes a Very Dull Chef’s Knife and gets it sharp using only a SharpensBest.com knife and tool sharpener. www.SharpensBest.com
Great Video Brad ! Love it you Dull the knife which a lot of your viewers want to see done any sharpening tool you use you are going to take metal off hands down Yep I agree all I want is a working edge thanks buddy enjoy your trip !
great great great vid n content my brotha brad , you tell em , the haters n trollers are coming from competitor's out there , you know who brotha ! , thanks n talk soon > tom !
Sadly, I did see a benefit in the Sharp N Spark sharpener. I used it for about 6 months straight sharpening any knife I could get my hands on each weekend. Chef knives, pocket knives...etc and got a nice edge on it. Over the last weekend I am finding that it is no longer working. I reached out to Brad with questions which I haven't heard back. 1. Can the Tungsten edge get dull over time and not sharpen the knife? 2. If that is the case is there a way to fix it?
1. Can it get dull over time and not sharpen (or take longer to sharpen) a knife? Yes. Will it? Eventually. I doubt it would happen over a period of 6 months or that it would happen suddenly. It would probably happen over a period of years or decades of use because tungsten carbide is so much harder than the materials you're trying to sharpen (9 on the Moh's scale vs. 4.5 on the Moh's scale) that it would be like water eroding marble or obsidian. To put it another way, I've got an Accusharp that Dad bought in the early-90s. He didn't use it a lot, but he used it some. I've been using it a good bit (1-2 knives a day, most days) the last few years. It still has the original tungsten carbide "teeth" in it and works fine. I might need to replace the teeth eventually, but I doubt it will happen for decades to come. Maybe if I was doing hundreds of knives a day, every day; but not with normal use. 2. Probably. But returning those corners to 90° angles would probably would require expensive machining equipment since whatever material you use to true the carbide would have to be hard enough to cut tungsten carbide (so over 9 on the Moh's scale or over 2600 on the Vickers Hardness scale) and precise enough to maintain a flat edge. That probably means some sort of diamond grinder/file/plate. Personally I'd suggest you keep trying to contact Sharpen's Best and/or Brad before trying to "fix" the sharpener yourself.
I didn't understand your sentence sir. Probably bad punctuation. Let's be clear: if you want to create and sharpen a perfect edge, yes, you would need a set of stones (diamond and ceramic plates work even better) and then a strope. I know, I do it (look at a few vids in my channel) . There you will achieve a beautiful, mirror finish hair whittling bevel/edge. True. And? Buckner is right: this is all for bragging rights. This is hobbyism, there's nothing wrong with it, but this is not gold standard on how to obtain functional cutting tools IN ALL CONTEXTS. It's quite the contrary in fact, considering how many costly gear, time and practice it requires to achieve beautiful edges. AND : a hair splitting edge is gone in the first minute of real usage NO MATTER THE STEEL (yeaah even REX 121 at 68HRC will NOT maintain a hair whittling edge in any usage, that's just fantasy. And then what remains is the geometry : max 30° inclusive for a camp knife, 25° inclusive for a kitchen knife. The absolute apex is gone but the geometry is there to do the cutting/shearing/wedging. So what he is advocating is how to create a quick functional sharp edge fast, with a single tool. And I see NO reason tungsten carbide couldn't shape an edge to be functional. If your knife can cut receipt paper, it's sharp enough for 99.9% of your needs. Just don't try and shave your face with it. Use a razor for that. You're all just redditors, armchair experts.
