KnifeCenter FAQ #84: Is D2 Hard to Sharpen? + Scottish Kilt Knives and Sharpening Choils

[@michaell397]

"D2 takes a lousy edge and holds it forever". It was it was a quote by R.W. Loveless as he remarked to Dozier as to why he did not and would not use it. Loveless and his business partner in the Loveless Shop, Jim Merritt and I were close friends, and I fully disagreed with Loveless on this point. (So did Jim secretly). Mr. Loveless brought us 154-cm. flew t Japan and convinced them to make ATS-34 when 154-CM became hard to obtain and RWL-34. Super steels in their day and were the first to really open the eyes of what was possible with Stain Resisting Steels, when stainless steel was basically pot and pan metal in cheap knives. A stigma still held by many who are not privy to what is really available today. Bob. Loveless was quite impressed with the edges I got on D2. The issue is the Vanadium in the steel. On the other hand, many steels have much more vanadium and they too require a sharpening medium harder than the Vanadium carbides in which can be up to 81 HRc. And this is the very reason so many people complain that they are not getting the long lasting edges with such steels as SV-20, M390, S-110, and S90v. (ON a side note, as far as I know, Corbit Sigman and I were the only two makers who could fully and flawlessly mirror polish D-2. Some could pull it on one some batches, but rarely. Yeah, we had a secret. LOL! Now who in the history of edged weapons, knives, implements, through out history has ever had a secret)? :

As a child in the 60s, wanting to work, prospective employers told me to come back in ten years when I'm old enough to be hired, so I decided to learn a skill so valuable that I would have my own customers and I'd produce quality so high that my youth would be overlooked. I learned to sharpen from old people who would shave with the straight razors they sharpened which was even then a dying art. I took it further, teaching myself, using a surgical microscope. Seeing my dedication, I got the gift if the book: "Custom Knives and Their Makers." I was trusted to sharpen these extremely valuable knives. My brothers got what they wanted in stamp and coin collecting and I got what I wanted which was to be dropped off at the doorsteps of those custom makers. I asked them to show me all of their secrets and was typically greeted with a belly laugh and explanation that no one gets their secrets. But, they individually relented with the notion that I was just a kid and took me in and showed me everything including what even their competitors didn't know. They all had their secrets! Generally, it was not so much the equipment and modifications, but their techniques and extraordinary skills. I might be the only person in the world alive today with the advantage of knowing the secrets of these famous custom knifemakers listed in the back of that book with their addresses. I went on to become a machinist and studied metallurgy and used the best of machinery and manufacturing equipment. [e-mail]

I love D2, never had a problem sharpening to shaving sharp and put a mirror edge on it!

[@drbadzer]

With D2 being my favorite steel, it comprises 60% of the knives in my collection. What I learned is that D2 is very very hard to properly heat treat and the quality of the metal will depend on that even more than other steels. A well heat treated D2 can get sharper than a standard razor and keep that edge almost as long as an M390. I have a Maserin Reactor knife in D2 that keeps a shaving edge 30% longer than an M390 knife.

[@jeremydarkcountrysteckman9496]

Mine too but my favorite version is the sleipner I also love bohler n695 joker knives does a great job with it my favorite knife is my joker nomad

[@hjjj3821]

How can you tell if its been heat treated properly? Do you just sharpen it and test it? Also, do you know where I can find more information about this?

[@poonbandit9924]

I have two knives in D2 that hold a razor edge really well and aren’t terrible to sharpen to razor levels. I have 3 knives in d2 that I could spend two hours on the stones and not get a great edge on because it just rolls a fine edge. S30v and the likes tend to have better heat treat with the premium view and as such sharpen well and hold the edge. D2 could be right there with it if it had the Paul Bos heat treat, k110 is. Solid example too.

[@Freak480]

If d2 is outcutting m390 it's because the m390 is heat treated horribly. D2 is a quality budget steel but it's use of almost only chromium carbides (and quite a lot of it for an ingot steel) caps it edge retention at a pretty low point. If we assume all steels are heat treated ideally then d2 will cut within spitting distance of s35vn. That would place it above 3v but still significantly below s30v and especially m390. Additionally, and decently treated steel can be gotten razor sharp. D2 isn't terribly difficult to sharpen but still isn't no where near as as easy to get a screaming edge on as something like 1095, aebl, 14c28n, or (in my opinion) 440c.

[@michaell397]

@@Freak480 It is quite true that m390 is often poorly heat treated. Far harder to heat treat than D-2. and why it is so often lack luster. Properly heat treated to at least 61 hr-c, is outstanding! D-2 is mostly heat treated to 57-58. I was one of the people who pioneered the 2+2+2+ method of draw for D-2 and run it at 61-63 Hr-c. So treated, it is not brittle at all and colds a screaming edge for a very long time! KnifeMaker/Retired after over 47+ years in the Craft

[@atongs_edc]

The trick with D2, or probably with any other knife steel is to not let it dull too much. Practice honing or stropping after every use, if possible. In that way you wouldn't have to resharpen the blade, but just regularly touching up the edge. Hope that helps. ✌🏼😁

I am pretty new to folders, and have got three new folders with D2 the past 3-4 months. I use a Work Sharp Precision Adjust and have no problems reshaping and sharpening to shave hairs on my arm. I like D2. I have sharpened both 18 and 16 degrees with no problem. These knives are slicers. I do not use them cutting metal, chopping trees etc. For my use it works. I've read that those large carbides makes the edge almost micro serrated, which may be an advantage for some materials. I also think my CRKT Pilar III with D2 is a candidate for an every day EDC. It came with a rather acute edge (about 17 degrees each side), and I did a reshaping to 16 degrees. Cuts paper, hair, paracord and tomatoes like soft butter. My first D2 was an Adimanti Skimen D2 (made by Ganzo). I just love that design and its slicyness. So much in fact, that I got a second one for harder use, so I can keep my first one collectible. I have put an 18 degree edge on both.

In my experience with D2 it’s the heat treat that makes it able to get a sharp edge. Even then it’s definitely not the easiest steel to sharpen and get a hair popping edge on. It takes patience no matter what but some D2 I’ve never been able to get hair popping and some I have.

[@ramonade_knives]

I agree, D2 or K110 with poor heat treat are awful to sharpen. If the heat treat is good enough, it'll just take some time but it'll get as sharp as any steel :)

The Sgian Dubh is usually worn inside the sock, and held in place by friction, sometimes with a simple elastic band under the sock. Back when the English forbade the wearing of any weapons by the Scottish Highlanders, the Scots had to get creative in hiding their knives, since swords were definitely not allowed. Dirks were worn behind the back, and the Sgian Dubh was worn inside the sock...out of sight. Nowadays the Sgian Dubh (black knife*) is usually mostly decorative, with a 3 to 3.5 inch blade, a flattened handle (to fit closely alongside the leg), and made of horn or stag and often with a "jeweled" crown. A good modern folding version of a Sgian Dubh is the Cold Steel Hold Out. *The original Sgian Dubh's were often made with black ebony handles.

[@gimliismyhero2045]

Kilt wearer here. For a modern Sgian Dubh (“Skeen doo”), check out the Cold Steel Secret Edge (fixed) or the Cold Steel Hold Out series (folding). AUS8 on the Secret Edge, perfectly usable, but also wish they offered a better steel option with better edge holding as well. The Hold Out series is great; I’m disappointed they discontinued the most useful 4” length version - wish they’d bring it back. Side note: Sgian Dubh translates to “black knife”. It used to be a hidden knife worn in the armpit region, but is now often worn as a sock-knife, tucked to the side of the leg. Story as I heard it, is that one would tuck the hidden knife in their sock as a gesture of trust, friendliness, and non-aggression when in company of trusted companions.

Frankly...I don't know how you guys do it all, but it brings me A LOT of joy. Anyway...I have an annual anniversary I wish to commemorate with an engraving. I am thinking fixed blade, but that isn't written in steel (couldn't help myself) I would like it to be an EDC. Not opposed to a pocket carry fixed blade, which I know you are partial to. Leaning toward perhaps traditional/modern traditional. Handle styling and fit and finish over blade steel type, with with a primary bevel that is ground for cutting efficiency. Something maybe a bit off the beaten path, but again...it really just comes down this. I respect your opinion, and I would like to know what you might by for yourself in my situation. No wonder you wanted more info huh? I'd love it to cost under 150, but 200 max. Keep up the great work DCA, Seth V, and Reverse Tanto Thomas.

I, too, noticed that my SPEW didn't have a sharpening choyle. Glad someone thought to ask. As far as sharpening D2... I use automotive sandpaper that's designed for tool steel.

*Yes it is!* Speaking from experience. D2, A2, and literally every steel classed as a Tool Steel is a nightmare to resharpen once it goes dull. Folks love to talk about how amazingly long such steels stay sharp. True! But the nature of Tool Steels is why they stay sharp for such a long time. The are super hard. That's their nature. So, when they do get dull, good luck sharpening them! You'd have an easier time challenging a Sherman tank while armed with a toothpick! As much as I love my two custom Bob Dozier hunting knives I bought in the 1990s, those will continue to be the ONLY D2 bladed knives in my collection. And, sadly, they don't get used.

If you ever see titanium on an edge, I think it would need to be "carbidized" so that it would have some wear resistance.

what are some of your favorite big slicey knives , think similar to pmp spartan or civivi mastodon

[@danofiremano]

Hey David, is it true that a chisle grind is stronger than a double bevel & that's why Benchmade used it on the 591BK Boost, that was made as a pry-bar knife for Diesel Mechanics?!?

[@Edwinthe7th]

Hey, DCA, I'm looking for a knife for my dad sub $300. He works outside and often breaks tips on knives, and if he doesn't break them, he rounds them off when sharpening. He wants something he can one-hand open and close and preferably USA-made. His favorite knife years ago was the Kershaw Leek, so something in that size but less likely to break. Thanks for the help. Ps thought about a tanto to love the sharpening issue.

Does cold steel do a triadlock on a knife that is like the buck 110 , because that would replace my 110 in a heartbeat.

The first time I came across the D2 quote was from a certain David C Andersen back in the TTAK days. I still think about that as I sharpen my D2 blades (often!)

[@knifecenter]

Hey there Stuart! At least I'm consistent lol -DCA

[@kevinmadrigal9090]

The condor primitive bush dagger might work for a Sgiun-Dubh The sheath isn’t right but it’s pretty and I bet some DIY leather work could make a sheath with a tab ( similar to Matt Graham’s other desighns) that would nestle in a sock quite slim

[@sethlange7613]

I was also looking towards Condor for a solution. What stuck out to me was their Cavelore. And for something more modern, SOG Pentagon FX. Though neither are lightweight. While the SOG doesn't have a leather sheath, it seems ready to fill the role of modern Sgiun-Dubh. But I am not Scottish, so WTF do I know?

[@seanf5760]

The extra second life D2 got was when Crucible did CPM D2 which made the carbides smaller and allowed for a finer edge and better edge stability over ingot D2 while still having a similar toughness and edge retention.

[@seanf5760]

Also for adding that sharpening choil, I'd advise round chainsaw rat tail files. Less risk of overheating like a rotary for the bulk cutting material, then use a fine grit flap or barrel end on a rotary at a lower speed to achieve the fine grit smooth finish. Just keep cool water flowing over it slowly (keeping the electric part of your tool out of the water, of course) and it'll get you a nice polish without compromising things.

[@AJLikesCats]

Hey DCA, and Thomas too! Sorry about your little disease vector! 😸 Hope you and her stay safe! I recently began letting my indoor cat take little excursions into the yard, and I've been using a couple Cold Steel machetes as cat defense tools. Poking around in potential snake holes, clearing some brush, light chopping, that sorta thing. They're perfectly serviceable of course, but because I have Knife Guy Brain Disease, I've been thinking about upgrading. Having trouble picking one, though. Preferably around or under $100, but I'm flexible. I'd like it to come with a pretty nice comfortable handle out of the box, maybe micarta, but I know that could raise the budget. I think I'd also like it to be a bit longer, maybe 18 inches? You know, to really get some distance from those terrifying garter snakes. I don't love the black coating on the ones I have, but I've seen that on many from other brands as well, like the lovely Condor Golok. How important is it to have that coating if I'm prepared to oil carbon steel after use? TL;DR Nice machete around $100 for yard work and critter menacing. C'mon, you know you want to put a couple nice big fixed blades on that table. Thanks!

[@bowen1189ify]

Greetings DCA. What's the easiest knife grind for "cheap" knife makers to use to cut corners? No pud..... Thanks

[@josephlilley9249]

I also only have one titanium frame lock flipper myself lol it's not the hinderer Jurassic, though I've seen them in stock all around lately and may pull the trigger one one of those or a firetac. Mine is the new chaves ultramar street liberation in full TI with a drop point that just recently came out. I've wanted a street liberation since reate first started making them like 3 or so years ago and I also want a redencion but couldn't find any for less than 500 so when I seen these were dropping a couple weeks ago I had to order one as soon as they dropped and I freaking love the knife. If I had any complaints about it, the one complaint would be the corners on the back of the knife are a little sharp when flipping the knife. You don't notice when using, only when flipping and they are that sharp, but could definitely be rounded a little more.

[@arrowheadguys7637]

Thats cause everyone is tying to get rid of their Hinderer's and no one wants to buy them after that BS lawsuit of his against that kid who exposed him out on his bad heat treat.

[@J3RK115]

Question: my CS Recon 1(Tanto w/ Serrations) has a Chisel grind with the DLC coating. Since one side has no actual grind, the coating covers that entire side. Will that affect the cutting capability? No issues yet but I don't do extensive cutting with it.

[@shannonandsheila1403]

No if anything it will cut better

[@tommymccombs4309]

If you are looking for a D2 blade you can ultra sharpen. I would recommend the Kershaw Sinkevich Concierge Liner Lock Knife Brown Micarta (3.25" SW D2) 4020MCB and also in Kershaw Sinkevich Concierge Liner Lock Knife Green Micarta (3.25" Black SW) 4020MCG they are a hollow ground blade.

[@janreineke7275]

Ontario Rat1 or Rat2 might also make some good hard use folders. They're reasonably tough and cheap to replace.

[@bobdayton9608]

I have several D2 steel knives. I also have a variety of different sharpening systems, including the KME. Several of the sharpeners do fine on D2. I have no problem at all sharpening D2. Just be sure you have a decent sharpener.

[@jmuhr8952]

From experience like many others have stated the edge you’re able to get on D2 has a lot to do with the heat treat. I have tons of D2 knives and everything I sharpen with or use being identical, some come out super sharp and others not so much. Either way I’m not a fan of D2 and usually only but knives made of D2 for beater knives or because they’re cheap.

[@jeremydarkcountrysteckman9496]

I use worksharp Ken onion now but I use to hone by stone it will take a hair popping edge but it takes alot longer than say 1095 but once I get an edge I like it only takes a few strokes on a ceramic once in a blue moon never have to actually profile it again

[@kniceslice780]

My RAT1 with D2 gets shaving sharp with my Worksharp guided field sharpener, 20 degree edge. It does take more time and patience than my AUS8 blades.

[@dayontapout]

I've been buying a lot more knives in S35VN and I've noticed, not a huge difference, but a decent difference in stock edge. I've got a few different SOG's, a Cold Steel Lawman, and a Civivi all with S35VN and they don't really act the same when doing simple cuts. I admit I don't know much about the purpose of blade shapes so I'm guessing that might have something to do with it. Also I have a SOG KIKU xr lte in CTE XHP and I don't know what the hell that means.

[@Ericstraordinary]

The differences in stock edges could come down to heat treatment, blade stock thickness, edge geometry and individual technique used by whomever is sharpening at the factory. CTS XHP is an American steel that has been referred to as a "more stainless version of D2". That is probably a gross oversimplification but it makes sense to us laypeople.

[@dayontapout]

@@Ericstraordinary of that's the case with XHP then I significantly over paid for this SOG

[@Ericstraordinary]

@@dayontapout LOL. I wouldn't necessarily say you overpaid. Remember, D2 is more of a generic "recipe" for a type of steel that is manufactured by different companies with different levels of talent working for them. CTS-XHP is exclusively an American-made steel made by a specific, well-regarded company.

Hey DCA, Q's how do you put a toothie edge on a folder.. I'm a knife nut and own way more knives then any normal human would ever need, however my wife puts me to shame, she uses her knife like a champ she's a brewer and needs to open a lot of grain bags either double wall paper or woven plastic. I've always put a mirror polish on her knife, but I feel toothier edge would be more beneficial. My wife's current knife is a Benchmade mini grip S30v. Ps don't like serrations.

[@inthemwoods523]

I've been wantung to try my hand at D2. It can't be much more difficult than Buck's S30V. I had to upgrade to water stones and good ceramic rods to do their S30.

[@arrowheadguys7637]

I'd say S30V and D2 are fairly similar in sharpening, though the data would say D2 is harder.
