KNIFE TALK: WHAT GRIT FOR WHAT STEEL WHEN KNIFE SHARPENING

bang needs knives i'm jared my lovely wife cara is at work and today we are talking about different steels and sharpening those steels and what grit should you use on those steels what grit performs the best on each individual steel now there's a lot of variables in play when you're talking about that and i think that's why a lot of people haven't done this video because you know you got to speak about heat treating hrc blade geometry edge geometry there's so many variables but i'm going to do my best with what i think um you know when i think of the steel now like i said the variables lots of things can change you know depending on the um the the angle you sharpen at that's one thing so if you have a shallower angle it might be a stronger edge but it won't cut as well if you have it at a more finer edge and it's laid back farther then it's going to cut better but it's not going to be as strong so a lot of factors come into play here but i'm just going to basically do my best and i'm no metal urges i'm no professional i have been sharpening knives for a long time now and this is just in my humble opinions now i also want to say that most steels do get longer edge retention from a polished edge but they do but some or a lot of them do not cut as well so depending on how often you're making your cuts and what you're cutting you might want more cutting performance rather than edge retention like if you're only making a couple dozen cuts in a day before you go home and strap your edge you might want cutting performance over edge retention now if you're not worried about cutting performance and you'd rather just have edge retention instead of you know it cutting the material easier or better then maybe you might want you know more of a polished edge and then also it depends on what you're cutting because a polished edge might cut some certain things better than a toothy edge but usually a toothy edge for edc cuts a little bit better than a polished edge because some steels at very high grits or at higher grits tend to skate across material meaning they don't bite into the material like if it had a little bit lower grit so it'll tend to just slide off the material rather than bite and cut into it so that's where a lot of this is going to depend on the grit and like i said lots of variables make things different let's get to this first up i'm going to show you some graphs these graphs show you basically um toughness and edge retention toughness is basically how hard the edge can smack something you know before it deforms or chips and then edge retention is how you know like how long it's going to cut until the edge starts showing damage or wear obviously you know depending on what you're cutting but some steels do perform better with certain materials so like i said variables ease of sharpening is basically just how long it takes to sharpen some knives sharpen up faster than others it all pretty much takes the same amount of effort maybe some a little bit more effort but um as long as you're using the right stone i think that's where it's really going to uh play a big part whether or not you're using diamonds or you know aluminum oxide or whatever stone you're using for the right steel you know or this you know using the right stone for the right steel and some are going to take a little longer than others to sharpen some a lot longer than others to sharpen okay first i'm going to show you some grip patterns this is about 300 grit this is on 14c that's why i put it on this edge this is about 600 grit and this is 800 grit this is a thousand grit 1200 1500 two thousand three thousand grit and this is about three thousand two the last two about the same and then this jumps up to about 5000 grit this edge was a little dirty i think i got a little better shot here but it's basically a mirror edge you see it right here this is the same edge but it has been used i personally like between 600 grit and 1200 grit finishes usually the most on most steels some steels do perform better with higher grits but i personally like between six and 1200 grit myself on my own personal knives and you know just across the board on most steels but some steels do perform better at higher grits now let's get into this let's start off and no none of these knives are in any particular order or none of these steels i should say or in any particular order if i say one in front of another that doesn't mean i think that that one or that doesn't mean that that one outperforms the other one i'm just basically just grabbing you know it's all random it's just random so let's start off with some hcr which is basically the bottom of the bucket you know it's not quite the bottom bottom of the bucket but it's floating at the bottom of the bucket hcr 13 mov i think it's uh you know it doesn't have great edge retention it's not going to last very long but it does have decent um stain resistant decent not the best but it uh it does good at a high grit i don't think it does bad at a high grit um i don't think you want to take it too high but i think um between 1500 grit and 2000 grit is just fine i think it'll perform good at a low grit too i think it's kind of an all-around steel next stop os eight awesome i kind of find this basically the same way i kind of find it very similar to hcr possibly a little bit better but i also think that hcr does a little bit better um at a higher grit i don't i'm not saying that this does bad at a high grit i just think that it skates off materials a little bit easier at a high grit i think it does a little bit better at a medium like you know a thousand fifteen hundred grit um you know i i don't know i wouldn't personally take it over fifteen hundred grit unless if i just really wanted a polish or if the blade and edge geometry was right and could handle it because like i said you know the finer the edge the more capable it's going to be at cutting now you know low grit even though it has more bite doesn't necessarily mean it's sharper it just means it has more bite 440c 440c i like 440c i've done it a lot and it performs well all across the board it does good at a high grit and it does good at low grit um this one i have at a low grit this one i have at a high grit they're both really good um obviously a low grit is gonna have a little bit more bite but you know anywhere between i would say 600 and 3000 grit it does great so there you go next up by the way i'm sorry these were both the rat ones and then this was a cabela's knife and then this one is the ganzo f756 and then this was just a cheap m2o uh smith or wait no mmp knife sorry uh let's get to the next one next one we will go to 9cr this is the ferrum forge mini archbishop 9cr i find is a lot like 440c i personally like 440c better but um 9cr it's a lot like 440 it kind of does good all around the board um so i think you know like i said between 600 grit and 2000 grit i think it does great um i think at some point it does start getting a little skatey but it can still perform pretty good at a high grit you just you want to make sure you don't polish all the teeth out n690 in 690 i think uh does good at a uh medium to high grit um i think it also does good at a low grit like it doesn't do bad but medium to high grit i'm going to say a thousand to two thousand grit it does pretty good um now will it do good at a even higher grip probably you know depending on the knife you're sharpening but it's a good all-around steel it's it doesn't have like a really particular edge it wants you know a lot like 14c 28n and 12c27 they are a sandvik steel they um i love this steel um i really love 14c 28n i find it better than 12c27 but they both do great across the board whether you want a polished finish toothy finish they do great so um it's just a good all-around steel they were made for pocket knives so that is a thing you know maybe that's why it does so good all around the board because it was uh made for pocket knives but it just does good all around the board whether it's um and also it does good at low hrc numbers too so it's a steal that does do good at 56 you know 55 56 hrc and this was the tucson ts-129 and this is the sam remnew 9 1 0 or the san remnu land and then this is the kaiser lieb i'm sorry i keep forgetting to say the knives nitro v i find nitro v um a lot like the sandvik steels it seems like it uh you know pretty much takes just about any edge you you really want to put on it i tend to like you know between probably eight and 1200 grit on it but it can definitely go higher to 2000 grit you know um and even probably up even higher um i haven't sharpened a ton of nitro v but uh but from what i have you know it seems like it's kind of an all-around steel it seems like it does pretty good at a low grit and also a high grit um i polished it before and on this one i did 1200 grit and uh you know it came out really really sticky so next up vg10 vg10 uh you know it's kind of the same way like um where it does do good at a high grit and a low grit um i find that uh i personally usually do it you know like it depends on the knife some knives i do it at low grits some i do it high grits you know and i've never really found it to not really like a polish it likes a polish pretty good um and it keeps a good bite so you can definitely do a at a high grit or a low grit you know so between 600 and you know 5 000 grit i would say and this is the kaiser mini sheepdog and this is the kaiser v3 vigor aebl this knife is the cody ussler duckling now aebl was made for razor blades so the little razors that you find in like gillette razors that you shave with that's where aebl came from so it does really good at a fine grit or a fine edge now it also does a lot but it has a lot better performance when it is thinly ground so that is a factor you don't do want to put into play but finer grit high grit it probably performs the best obviously you don't want to you know for a pocket knife because a shaving razor something you shave with you know you want a very high grit because you don't want any teeth on what you're shaving but with a pocket knife you do want a little bite so just don't polish all the teeth out and it should do good at a high grip but remember you always can polish something too much especially for a pocket knife it kind of defeats the purpose if it's skating off of stuff but it does do a ebl does do its best when it's thinly ground next up cpm 154 now this is the cody ussler dunk so the the last knives big brother now cpm154 in my humble opinion does not do good at a high polish now it does polish very nicely almost too nice and i feel like that's the problem it polishes incredibly fast almost way too fast and you tend to take all the teeth out and all the bite out so in my opinion i think it does best at a lower grit um i would say between 600 and 1200 grit i think anything over 1200 grit you're just polishing all the teeth out and yeah it turns into a mirror fast but it's going to be skating across everything you cut and what i mean by skating is that when you go to cut something it literally just skates right across it it doesn't bite into it you know to cut it you want your blade to cut into the material not just slip right off next up 154 cm um i have some right here where is it doesn't matter it's basically the same way but i find that it does do better at you know at a little bit higher grit now it's very similar to cpm 154 but i find that it does hold its bite a little bit longer um now and cpm 154 polishes faster so i'm going to say you know between 12 to 1500 grit but that's kind of an all-around good steel too cpm 154 154 cm is just a great all-around steel it's easy to sharpen good edge retention and it's easy to work with that's why lots of custom makers like to use it you know we might as well put ats 34 right in the same category with that one um i don't have any here but we'll just put that in the same category let's go to s30v cpm s30v is a good steel um i mean it's not a bad steel i find that it does good at a lower grit i'm just going to bring s35vn right in here with this so we got s35vn so this is the the benchmade bug out this is the spyderco shaman and this is the terzola um c t f the drop knife so um in here here's another s35 this is the the cevi elementum so we have two s35vns and two s30vs now s35vn is a little bit tougher and or a little bit stronger than um s30v but s30v has a little bit better edge retention some people say s30v is chippy and i have found that to be true in some cases but not across the board um so you know i don't know i think it depends on who's doing it but um but anyways i find them to do best at a low grit now this one i have actually a 5000 grit finish and it's an okay edge it's not a bad edge it does good at a high grit it doesn't do bad but it tends to skate across materials um a little bit more than when you use a low grit so i just i personally find it to do better at a low tim or low to medium grit so i'm going to say between 600 like what's on here right now that is sharp 600 and 1500 grit and in all reality a low grit would be like 400 grit but um i'm saying low you know i might you know i do use 400 grit finishes on some knives but you know i'll definitely mention the grit when i say it so sorry if i mix up a little bit of the medium and high when i say medium and high or medium and low cts xhp that is the spyderco mcb this is the spyderco techno 2 and the ck knife works misfit and these are all cts xhp now cts xhp i find is an all-around good steel i think it does good at a low grit or a hybrid a lot of custom users like to use it it's a great steel um it has pretty good edge retention it's easy to work with easy to sharpen um but yeah i find it polishes really good like really really good and uh you know sometimes it may be a little too good so you might not want to go too high of a grit you know but it depends on the blade geometry everything else but it does do good at a high grit and it does do good at a very high grit so i would say 1200 and up for it does best so it'll do good at 3000 grit it'll do good at 5000 grit so but i wouldn't sharpen it lower than 1200 grit but you know it's no i'm not gonna say that it'll still do good at six eight hundred grit but um the edge retention i don't think it's gonna last as long so i think that you know 1200 grit and up is really good for it d2 and cpm d2 this is the ganzo fh12 this is uh another civilian lamentum the one in d2 and then this is a medford eris okay so cpm d2 is a powdered version of d2 they're almost a stainless steel but not quite a stainless steel now cpmd2 is going to be a little bit more stainless than regular g2 but i find that these do best at a low grit so i'm going to say between 6 and 800 grit not saying they won't polish up but they you know they just perform better at a lower grip it's a tool steel okay m390 m390 was originally made for the plastic industry so that's what originally comes from so it could possibly cut plastic um you know plastic things a little bit better than other steels but let's get into 20 cv and m390 20 cv m390 and 204p so this is the the ritter hogue the rsk mk1 this is the wii snacks this is the giant mouse ace biblio and this is tucson ts-129 now and this is the gareth ball chamois just because i had to sit here i even got more 20 cv should i pull out more i'm not gonna don't worry okay so 204p 20cv and m390 all do great at a high grit they also do good at a low grit um you know this is definitely going to be based on a good heat treat but when it's done right it does great at a high grit it also does good at a medium medium to high but it does good at a really high grit as well you can get this up above 5000 grit this one's at 5000 grit right now and it'll still whittle hair um and sometimes you need a knife to be a little bit lower of a grit to widdle hair so that it has the bite um not necessarily low grit but you know lower of a grit and a lot of times when it's a high grit a really high grit it just skates across the steel so m390 can do very very well at a very high grit and so i'm going to say 600 up all the way up to 5 000 10 000 grit you know whatever you your heart desires let's go to the next one s90v this is the benchmade 940-1 s90v now i've heard people say that it does really good at a really high grit and that maybe i prefer it because i'm not saying it doesn't do good at a high grit it could i prefer it uh at medium to low high so 800 to 2000 grit is where i like it that might be just me but i you know i do like biting my edge so that could be just my humble opinion but that's where i like it but i've heard people say that they like it at a high grit i just i prefer it or you know the way i prefer it i guess okay last two steals um i could put even more steels on here but i think this basically sums up a lot so s110v i'm not gonna speak on i've only done it a couple times um 600 grit is what i did it on and i loved it loved it loved it loved it i can't speak on it though i've only done it a few times and i'm not going to speak on something i've only done a few times all these other steals i've done dozens and dozens and dozens if not hundreds and hundreds of times so um and m4 m4 i'm going to be doing a live sharpening video on uh here in the next couple days but i've only done it a few times also so i can't really speak on it i don't know what i'm gonna sharpen it to i'm gonna see what the steel says so i can't really speak on it maybe somebody in the comments can answer cpms110v m4 and let's do a maximum at two i haven't had that much experience with maximum i've only done it uh i think one time and uh i don't remember what i put it at um to be honest so i think i did it at 1200 grit maybe it was a i think it was a thousand i don't remember i'm not going to speak again because i don't remember all right there you guys go i sharpen a lot of knives guys i sharpened a lot of knives i love you guys peace
