@MrRavenNation5 жыл бұрын
The spherical bearing idea to remove sloppy movement is a good idea but, the magnetic hold isn't terribly useful as many blades use non-magnetic or poorly magnetic alloys. Addition of either a spring clip or physical clamp would go a long way in improving functionality. Even use of a dovetail and spring to apply pressure to the stone would be beneficial in accounting for variation in those inexpensive stones.

@@juhotuho10 No. It depends on the usage area. In the kitchen stainless knifes are prefered for easy cleaning and long lasting sharpness, the drawback of stainless steel is the difficulty to sharpen it due its hardness. For hunting knifes most prefer a softer steel with a higher carbon content. Sure, you can't soak these knives for to long or they will rust. The edge is also softer, but, they are way easier to sharpen. Meaning that standing in the woods with a simple sharpening tool and a dull knife is no problem if it's carbon steel.

when sharpening, you should try going for longer strokes across the entire length of the blade instead of short saw-like movements. the latter might cause inconsistencies in the blade's curve or even a recurve section which can be very annoying when chopping (the edge doesn't touch the board perfectly and leaves a bit uncut at the bottom). Also with when you get to your fine stones, try "stropping" the knife with it. only pull back with the stone while using extremely light pressure for a couple passes on each side back and forth. this will even out the wire-edge at the end and make it sharper than the stone normally would with normal sharpening technique. Finally, I think you should spend some more time with the finer stones because the knife seems to want to snag the cutting board rather than slide across it, which is a sign of a saw-tooth-like edge. You stropped it well, so it can't be a wire edge, but rather a sawtooth edge left over from coarser stones. Either that or maybe the molybdenum-vanadium-steel alloy IKEA used is just very brittle and chiped while sharpening. I know that some cheaper, very hard and brittle steels can chip and crumble when sharpening, but this is rare.

You are grinding which is why the edge looks like a saw in your close up. Here is the process.. Pull the stone toward you with SLIGHT pressure on the blade. Make ONE sweeping motion from heel to tip across one stone swipe. So basically you PULL (forward stroke) the stone toward you and it covers the entire blade. LIFT the stone off the blade and reset back to the heel. The stone should not contact the blade on the push stroke (aft stroke). After a while drag your finger nail from the back of the blade toward the edge on the side you are NOT sharpening. You will evidently feel a burr as your fingernail catches it as you drag over it. This is a microscopic burr formed as the metal is rolled over. This indicates you are sharpening at the edge. You want to keep going until you can feel this burr across the entire blade edge. FLIP the blade and with NO pressure pull the stone toward you on the blade. This will snap that buff off. This is also referred to as snapping off the wire. Sharpen the new side by repeating the above. Reduce stone coarseness and repeat the process. Continually making a burr and snapping it off. The end result is the metal having an edge as sharp as the metal can be and it being SMOOTH.. Strop using leather (with or without polish) to maintain the edge. If stropped regularly you’ll never need to sharpen the edge again as long as it doesn’t become too dull or damaged. With maintenance the sharpening tool you made should only need to be used once or for reprofiling an edge. You made the tool but you are just using it like a grinder. This will definitely make a sharp edge but no where near as sharp as it’s capable of. If my instructions aren’t clear just download the manual for a high end sharpener like you made and it will elaborate better. www.edgeproinc.com/content/manuals/EdgePro_Instruction-Manual_Apex.pdf “Only sharpen on the forward stroke, and lift the stone off the blade in the aft stroke” It also should illustrations (albeit not well) of burr formation. Love your channel tho, keep up the good work!

You can have multiple angles on the same blade. Sharpen the blade at 10-15 degrees, then do a few passes at 15-30 degrees with your finest stone. This helps strengthen the edge, while giving relief for stiff vegetables like carrots. If you sharpened the whole blade at 30 degrees, the cutting edge often can’t make contact, and the knife ends up splitting carrots like a wedge, rather than cutting them.

Nice, however 3 issues, you should have used stronger magners (thicker) and bigger so they hold down the blade well, and add a clamp over the top of the knife, I know it has to be slim so as not to interfere with the stone, but from the video it looks necessary when your knife keeps moving and you're holding it by hand half the time. When placing the angle calibration, it skids on a rounded part of the tool, causing the set angle to be different from intended, make a stopper/inset for the calibration angle tools so they don't ride up on the inner curve of the tool.

But there really should be just a few things to improve. 1st knife clamp, the knife itself shouldt move at all, once youll sharpen expensive blade, id could do serious damage, magnets are great helper to hold knife before its tighten. 2. there should be 2 horizontal bars to prevent movement and make it easier to keep the right angle. 3rd stone holder should be adjustable, because piece of tape is not precision at all...4th make it more stable, because stability and lack of any movement of any part in any direction is the key. Overall very good idea and only little should be twaeked to have awesome and one of the most usable design over thingverse.

Finally, a useful 3d object:) But I have some concerns about the magnets holding the blade: Yes, ceramic magnets are strong as hell, but only towards ferromagnetic materials. Stainless steel usually isn't that magnetic, because it has very little ferrite inside its structure. Perfect austenitic stainless steel shouldn't be magnetic at all I think. Also, many knives have a very small flat area, the rest is already in an angle (the grind), consequently leading to the knife on the sharpener to tilt arount a little bit, messing up the blade angle. I assume your design is still very innovative, even when not flawless, because the mechanical clamp on the back of the blade, that is used by most commercial products, is often in the way of the stone when the blade angle is low and the blade not very wide. I once had the idea, to clamp the knife on its tang instead of the blade with a vice next to the sharpener, works great, but only works when you take the blade out of the handle, which is obviously impractical... Maybe a soft jawed custom vice that universally fits knife handles could work, but I haven't tried it yet. Another idea for a future 3d printing project?

I like your thorough and logical approach to testing things so perhaps you could explore how to get the best supported horizontal surface? Supports seem to break away from complex shapes and leave a reasonable finish but a horizontal plane away from the built platform always seems to end up a mess when I try to print it. The support doesn't break away, or if it does it leaves a terrible stringy finish that's pretty horrible. Could you show us what can be done about it and explore the reasons as to why this is so difficult to get right? Maybe the only solution is to use dissolvable supports?

I have this knife too. And a 250€ japanese knife. The ikea knife is very good!

I think it's better to not drag the sharpener back and forth, if I remember correctly it is better to sharpen the knife in one direction, if that made sense. Like, only sharpen the knife when pulling towards you, lift it of the knife when going back. I'm not entirely sure though..

Great video! The spherical bearing mod really makes it more precise! I would prefer Diamond sharpening stones and maybe use a commercially available spherical bearing. An additional clamp could help keep the minor blade shift from happening too! Not trying to pick at your design at all, very high quality as are all of your projects! I can't seem to find the cad files referenced in the video - It would be great if you could provide a link to download the fusion360 file for this project. Thanks for posting!

I’m here because I need to get my ikea knives sharpened. Ikea knifes are so dull out from the box that they should have this sharpening kit included 😂

Oooh I've wanted a sharpening setup like this but ready built ones are far outside my budget. This might get it done.
