Grinding bevels on a knife, Knife making, Easiest way to grind a knife bevel

okay everyone and welcome back to the Channel all right out in the garage today um doing some bevel grinds it's been a while since I've done a bevel grinding video I've changed my methods a little uh since then so I figured I'd do a new one to show you how I'm currently doing it uh what I'm working on at the moment is these little Bushcraft knives to start with we need to grind a flat so here one that's been done one here that hasn't been done this is what it comes out like after heat treatment and there we go that one's got the flats cleaned up now cleaning out the flats also helps to flatten it a little bit even using the clamp to do the heat treatment doesn't necessarily come out 100 straight there can be some little defects in it um so by using the surface grinder we can straighten that out and for this using my 84 engineering surface coroner and that just straps onto my belt grinder uh fantastic little tool okay after we put down the magnetic Platinum it's just simply a matter of drawing them up and down adjusting the depth every time and you can see it's hitting in two spots not all the way along in the center of the blade there there's a little dip so this is where it's helping to straighten out the blade just up and down until we get that dip out and we've got all the nice shiny smooth surface so as we go along I just change out the belts and this blue 220 grit is where I finished grinding the flats okay I just use a texture just to mark up the face uh I know once the taste is all gone then I've cleaned up all the scratch marks from the previous Grit and once our flats are nice and clean just need to clean up that blade section um including up here into that pointed bit because once we do the bevels we don't want to clean them back to that um this is a size small wheels so I'll clean up the inside of these handles at the same time next up we're going to Mark uh the center line for the grind now I use this little jig here I bought it at a nice show one time I do not know who made it um but it's absolutely fantastic it's got a little carbide pin there um that works just to scratch The Depths on now you can use a drill bit put the drill bit down and just drag it drag the blade against the drill bit again it'll either mark but because I've got this this is what I use and we've got our marker where the grind's gonna stop and so all we're going to do black out the blade and you can use dicam or something like that I just find it just easier to use a permanent marker I'm just gonna drag that against that cardboard tip and we do that from both sides okay so that is showing all right we end up with some very fine lines there is a small Gap in between them which is hard to pick up on the camera uh but that's the line in the center is going to be the center so we just work towards that the majority of my flat bevels I just use a grinding jig it is quickest easiest this one's from used to be creative man it's now Nordic Edge um and it is the only one I've seen that accepts a file guide in it and the file guide Parts pretty important because I have three file guides I can set the file guides oh guys okay like that easiest to do it in The Jig it's tighten it up from the back okay and the fire guide holds it in place you can see there's our mark it needs to move a wee bit which may not be seen on camera um but there's our mark holds the height in the right spot I just need to put a clamp on it uh just to hold it um tiled it and stop it from moving um and I can set up the file guides on all three knives and just swap them over and just keep grinding so really handy that way hasn't got an angle gauge on it I don't really use an angle gauge I adjust the angle as a grind for this one I'm leaning towards a scandi grind or a saber grind and maybe a little bit less than that so it's going to be a fairly sharp angle on it but I can adjust that here to get that sharper angle and I will play with it as I go as I said I think these using these it's just quicker and easier I know that I can grind both sides and I can grind three knives both sides with the exact same results without playing around yeah I can do it by hand it's going to take a little bit longer this is a little bit quicker so why not use it all right the single thing I do not like about this jig setup is the clamp that comes with it this is the plan for it it's Allen key you've got a put it over the top so and then do it up tighten it up with the Allen key like so the problem is that takes away the versatility that I love about this jig because it takes so long to tighten it up undo it means flipping switching it backwards and forwards is a pain in the butt with it so all I use is just a little lockjaw and just clamp that on it's just quicker and easier means if I want to swap sides I'll do it turn around if I want to swap out knives out you know if in clamp it up so lovely and quick and easy that way with the little clamp that they give you with it yeah not so great so the only thing I'd recommend if you've got one is just to get a little Vice group let's see there's a gap on this side of the platen that's because the belt's hanging over this side probably about three mil um I find when I'm grinding if I've got that three mil hangover just softens the edge of the belt and it's not going to be as abrupt going into the bevel um as if I've got it hard against so yeah just a little three mil hangover grind that and then just adjust the tracking so it's hanging over this this side for the other one at this stage is where someone going half-blind with age glasses really help we want to just track how much meat we've got left there and how high we're going there okay that's a fairly even groin needs a bit more on this Edge you can do on my eye you can trace them out um but yeah it does work okay using a jig it is not the be-all and end-all it doesn't mean that you need no skills anymore once you use start using a jig which I think a lot of people I think that as soon as you get a g in your hand that's it you're going to cut cut perfect bevels it's not true uh if you come in exaggerated but if you come in on an angle like that you're going to cut too deep back at this end so your bevel is going to be too deep at the choil and in that case you're going to end up higher up here coming back down to that grind the other mistake you can make is you come in too much on this angle um and if you do that what you end up with is a gouge up here so if you come in on that angle and then go flat you end up with a gouge so that's pretty nasty so you want to come in nice and flat every time and keep your speed moving across and nice and consistent if you do that then you'll get a nice even bevel but it takes practice to do it it's not a matter of put the knife in a bevel go for it and you get a perfect grind every time so there's our bevel ground you want to make sure you're dipping in water fairly often because this is already a heat treated and tempered blade and you don't want to get the steel up close to the temper uh to the temperature that you tampered at because if you do that you're going to ruin the temper on the knife so nice consistent bevel come up a wee bit higher than I planned but that's fine there's still I've just come down to the first line there's still a little bit in the center but when I do the other grits take that away all right so there's the third one all finished off they've all been ground to this 40 grit which is the course of script that I start with and now we need to change belts okay so for flat grinding the next belt I go up to is this one which is a 120 grit it's a ceramic belt uh pretty high wearing uh you can see it's a bit dirty from use and that sort of thing but it's still got enough grid on it to the cats that we need so I'll go through on the 120. all right from the 120 we got to this belt which is a 220. uh this one's zirconium I did have a supplier in Australia but um the guy is not very reliable so I've actually had to order them straight from China um yeah I was on edge buying something from China but the belts came through and been really happy with them um really hard to find zirconium that's this high and zirconium stands up a lot better than aluminum oxide which is the normal grit on the belts for this grit a little trick what I do to show where I've cut a permanent marker trying not to hit the stand um this will go right into the depth of yeah all the all the scratches from the grit it goes right into the depth of those and that way you can see that you've cut through it the idea at this stage is we're trying to refine the scratches and get smaller scratches we can't get smaller scratches if we don't take all the scratches out okay really hard to get the end with the camera the way it is but you can see there you still got some of the marks that means it hasn't cut all the way through I normally find about three or four passes is plenty I normally do it just by looking at the grids but it's easier to do for a beginner you could put the texture mark on it lost up he for this stage is a 400 grit belt um as you can see this looks really really coarse it's another one of the ones I bought from China it is called a vertical stacked media uh the 400 grit stacked up which makes it more resistant and it has been working fantastic so far I haven't used it too much this is the first belt I normally go through these belts really really quick okay that there is my normal 400 grit belts as you can see it's really flat as opposed to this being really grainy and that's that vertical stack media these belts for a small knife like this I'd get by with doing both sides of this one knife and that's it this one's done a couple of knives and still holding up really well all right so there's our bevels all ground uh last thing we want to do before we go to Maker's Mark stage is just clean up the flats they were finished at 2 20. I want to get them to 400 the same as the bevels so all I use is just a welders magnet and then come back against the flat of the platen there's the finished result as you can see there's the Rough Side smooth off again uh now from here I'll go through put my Maker's Mark on and after the Maker's Mark I'll use a cork belt which is this one here it's just rubberized cork uh it's a 600 grit and I'll use that just hand do it and clean at everything up give it a bit more of a shine but I like to leave a satin finish because that's how I like to finish my blades all right thank you very much for watching and bye for now
