The Laziest Way to Sharpen Any Knife to Razor Sharp 2

in today's video I'm gonna be showing you the laziest way to shop in any knife to razor-sharp this is not a clickbait title this is actually the fastest method to sharpen any knife to raise a shark that I've ever encountered so this is a dull knife and I want it to be a sharp knife and using this method are now going to quickly sharpen up in under one minute so it's razor sharp now that it's done you can see I can shave my leg hair with it and it easily passes the paper test now that is pretty much razor sharp this method isn't just for sharpening small pocket knives you can also put the finishing edge on useful tools like lathes chisels on wood chisels make them really sharp as well on top of that you can shop and kitchen knives really easily or larger knives such as tomahawks and swords now I'm going to show you how to set this up and actually sharpen the knives properly then I'm going to explain some of the disadvantages and advantages of this method and compare this to other methods such as wet stones or commercial knife sharpeners so wait to the end of the video before you ask any questions in the comments down below so for the sharpening method to work you're gonna need three main things the first thing is going to be a bench grinder or some other rotary tool which is able to spin up the disc to a quite high velocity you could also use something like a drill press or just a power drill if you don't already have something like this this is gonna be the most expensive thing you can have to buy but you can get a really cheap bench grinder for about 20 quid that work I'll show you perfectly and I'll put a link in the description down below to one on Amazon the next thing you're gonna need is some sort of disc made from wood and I'm gonna be making this from plywood this is what sucks you're gonna spin and sharpen the knife my bench grinder is made for 150 millimeter grinding discs so I'm gonna be making this 15 centimeters in diameter it just so happens I have an elm circle for my lathe which is 15 centimeters in diameter so I just filled up to mark out the circle I mean it's got some very cheap 18 millimeter interior grade plywood and the creator of the plywood doesn't really matter as long as it's not the really really rubbish stuff and as long as it's not warped I use a jigsaw to cut out the shape of the disc you could do this with any other hand tool it's just easiest with a jigsaw and they couldn't cut the corners you don't have to be very precise as long as you roughly just stay on the outside of the lines we're gonna trim all up later the setup in this method is the most time-consuming part it took me about 15 minutes to get this all set up and it might take you a little bit longer if you don't have the power tools however once it's served you can sharpen absolutely tons of knives each one in about a minute so it still outperforms any other method I then drill a hole straight through the center which is gonna allow it to fit onto the shaft of my bench grinder now it's time to turn it true so that it doesn't vibrate the bench grinder too much answer the surface that is rotating that you're gonna sharpen the knife on is completely flat so in my bench vise I clump in a piece of metal round bar which I can use as a rest that I can rest my chisel on and start to remove the material very gently just using a wood chisel and I'm basically treating this as a wood lathe and it works really well to remove material needs a very smooth surface I carry on removing material until there's basically completely flat all the way around and one very important thing that I do is take my bench grinder and I spin it around so that it's facing in the other direction this is very important and I'll show you I you're on the surface of the plywood buffing wheel to be spinning away from the edge of the knife so that as it comes over it busted edge of the knife but the knife doesn't catch no matter what angle you put it on if you have it spinning towards the knife as soon as you put the knife on if it's relatively sharp it's just gonna cut straight into the plywood and it's gonna fire the knife straight at you and that's gonna be really dangerous and you could really injure yourself if that happened so make sure that it's facing in the right direction so the next step is to apply some buffing compound to the surface of the buffing wheel that we've just made as it is the plywood isn't hard enough to cut through the metal and polish the edge however this buffing compound contains tiny pieces of abrasive there literally like a couple of microns big and they will help buff the knife to a mirror finish by just removing tiny amounts of the hardened steel and actually the buffing compound is really easy to get a hold of any metalworking shops or hover or any polishing shops or have it and I'll put a link again in the description down below to this buffing compound which works great once the surface of the plywood is charged with the buffing compound it's ready to cut and sharpen the knife and you basically just gently brushed the knife along the edge of the buffing wheel and the compound will remove of material and mirror-polished the edge of the knife a couple of things that you can do to help get a better finish is apply less pressure and that actually makes the surface of the night even smoother and you get a sharper knife and also make sure that you hold it a constant angle on both sides and you'll develop both of these things after a little bit of practice it's really easy to get the hang of and it's not very difficult at all so now I'm going to answer some of the most frequently asked questions on my old video that I made on this topic and one of the main questions is that it's not the easiest way to sharpen a knife since you've got to do all of this setup so to answer that question you need to think of the main target audience for this method I say the main type of people this method is aimed towards it's people who make a lot of knives or people who use knives or tools like that a lot they need to be sharpened regularly and if you're using sharp tools like that along you generally have a lot of equipment like bench grinders and plywood and stuff that you can use to insert this method very easily and you probably have all of the stuff that you need to do this method already and you won't have to pay anything at all to do it so this method is ideal for people who need to shop and a lot of knives since once you put the initial setup in it's very easy to show up on knives however if you're someone who just has a knife that you want to sharpen maybe once a year this probably isn't the method for you there's easier methods they're quicker to set up but maybe they don't get as good results another issue with this method is it's not portable at all if you want to shop the knife you're gonna have to have this entire bench grinder some buffing compound and access to a power supply and you can't do any of that if you say camping or you're doing a bushcraft survival thing or anything like that you might as well just carry a knife sharpener instead and that brings up another issue about safety I really wouldn't recommend this to anyone who doesn't really know how to use tools safely and anyone who's not used to using spinning bench grinders or lathes and things like that if you did manage to get something caught in the spinning wheel then it could be really dangerous possibly even fatal with a sharp knife like that as well there's also the issue that maybe the wheel would explode a lot of people thought that that would happen and in the past I was using an MDF buffing wheel which would maybe a little bit of sketchy however this plywood I think it's easily strong enough to hold itself together under these forces although I wouldn't want to use much faster rpm on my bench grinder thirdly there's wet stones which is by far the most common method for sharpening knives it's been used for thousands of years and some people are really good at it and guess but razor-sharp knife probably sharper than any of these knives I would say in some cases wet stones are better than this method however in others wet stones were a lot so and if you want to get high quality ones it can be very expensive I have this set white students here which cost about 120 pounds for all of them and they are pretty hard to use you've got to be very skilled and very patient it takes me about half an hour to sharpen a knife all the way up to a razor-sharp whereas here only takes me one minute times when I would recommend using a whetstone over this method is say if you're using a very expensive knife and you don't remove a lot of material this method might be a little bit too aggressive so you might want to end up using a whetstone in the end for that method even if it does take a lot longer send the other method of knife sharpening that a lot of people mentioned a lot was just buying a commercial knife sharpener and some of these can be pretty good but in general the good ones are really expensive and a much more expensive than just buying a bench grinder like this and making something like this which is much easier and on top of that that you also have a bench grinder which is a very useful tool so I hope that you've enjoyed this video
