Does anyone on here have any experiance with DC53 steel. I understand it to be a Japanese version of D2 but slightly improved. I got a few peices of it and it seems easy to work with but I havent gotten as far as heat treating and testing yet. Any comments or ideas are welcomed.

sorry, never heard of it.
* Higher hardness (62-64 HRc) than D2 after heat treatment.
* Twice the toughness of D2 with superior wear resistance.
* Substantially higher fatigue strength compared to D2.
* Smaller primary carbides than D2 protect the
* die from chipping and cracking.
* Secondary refining process (DLF) reduces impurities.
* Machines and grinds up to 40% faster than D2.
* Less residual stress after wire EDMing.

I tried to import the picture with this but you can just do a search and check it out.
Ceya, would love to hear more about this knife and what kind of tests you did on the metal?

SKD11 JIS is listed as D2 AISI
Our newly developed cold die steel. DC53, is an improvement over the alloy tool steel SKD11 specified in Japanese Industrial Standard (JIS) G4404. It eliminates the disadvantage of insufficient hardness and toughness, resulting from high-temperature tempering found with SKD11, and is intended to replace SKD11 in use for general purposes and precision dies.
Features
1. Higher hardness after heat treatment than SKD11 : A Hardness of HRC62-63 is secured after tempering at high temperatures (520 - 530 oC). Therefore, DC53 exceeds SKD11 in strength and wear resistance.
2. Double the toughness of SKD11 : DC53 has relatively well-performing toughness among all cold die steels. Therefore, tools and dies made of DC53 are less faced with the problems such as cracking and chipping, which often seriously affect conventional tools and dies, and enjoy greater durability.
3. Less residual stress after wire electro-discharge machining : Residual stress is lessened by means of high-temperature tempering. Therefore, problems such as cracking and distortion are prevented during and after wire electro-discharge machining.
4. More machinability and grindability than SKD11 : DC53 is superior to SKD11 in machinability and grindability. Therefore, the use of DC53 is expected to provide relatively longer tool life and reduces the number of processing in die making.
The best I can tell they are saying if D2 gets to hot during the tempering process it gets brittle and its not as wear resistent. Easier to work with? but then again I never had anybody try to sell me somthing they didnt promise was new and improved. The biggest problem im having is the stuff is made in Japan then Imported here to Thailand and neither party can speak enough english to tell me anything about it. The only people using it here are the Japanese engineers at a Thai factory using it for blades in textile cutting and industrial metal cutting and they aint talking, at least not english. I tried to contact the one guy on here that used it but havent heard anything yet.

Here's a .pdf on it that's from IMSteel...
Maybe there's enough info there to figure it out...
Maybe there's enough info there to figure it out...
Sub-surface hardness decline of DC53 just below wire electro-discharge machining is much
less than D2; thus making DC53 dies more durable.
Stability
High-temperature tempering (520°C) allows maintenance of die accuracy without the
troublesome application of subzero treatment, reducing costs and increasing productivity.
Surface Enhancements
Surface hardening treatments such as CVD, PVD, TD, and nitriding require the use of high
temperatures. DC53s higher inner hardness than D2 after such treatments, preventing the
hardened layer from peeling off and making surface hardening treatments more effective.
Wear
Superior wear-resistance coupled with high toughness make DC53 suitable for use in
wear-resistant parts subject to impact and bending stress.
Strength
Dies made of DC53 and heat-treated using standard method possesses up to 25% higher
bending strength than D2. Secondary refining decreases nonmetallic inclusions and carbide
size for a substantially increased fatigue strength that of D2.
Toughness
Superior impact value minimizes fracture and chipping problems thus ensuring
more durable dies.

Im back.. it is better to email me.. I am getting back into knives and will help you as much as I can. I will send you my results. what do u want to know.
I first bought it in late 2000 in Japan. DMKnives was the one I had make my knife using this steel.
as far as I know I may be the first one here (USA) used it on their knife design..
Heat Treating is like D2..

Ceya Knives: TRIDENT WARRIOR!!!
--------------------------------------------------------------------------------
Ceya's TRIDENT WARRIOR FB..."live test!"
--------------------------------------------------------------------------------
Aloha all!
Permission granted from Ceya to live test his TRIDENT WARRIOR! Yeeeeeeeaaaaaahhhhhh, as this FB absolutely "cries out for use!"
Stuffed some old rolled up carpet in a pair of old denim jeans. Placed it on my "practice pole" free hanging by the belt loops w/ parachord. The TRIDENT cut rather deeply during slashes, and to me, any knife that can cut material of this density "free hanging" is a good one! Of course it cut through the jeans, but it also went through a FEW layers of the carpet. Damn! Following up some slashes w/ backcuts were quick, and left some nice "wounds". "Speed thrusts" left holes in the jeans, but didn't penetrate the carpet. I believe however, had the target been stabilized, the TRIDENT would've went in deep!
I then went into my forest and selected a piece of seasoned guava branch...about 3/4 in diameter. This wood is VERy pliable, yet HARD! I stuck it in the ground and delivered an upward angled slash from my right hip to left shoulder contacting the stick on the way up, then I quickly reversed the motion, contacting the stick on the way down. I was VERY surprised when the stick "fell in half" as my second cut met the first, thus splitting the branch!!! I tell ya, this was right out of a Samurai movie! LOL! Most times, the stick will go flying or I don't meet the first cut EXACTLY, PLUS it has been rainy as of late so the ground was soggy, making a less stable base for the branch. Cool!
I then wrapped a piece of plywood with the carpet. Did a few thrusts, the first being about 40%, then gradually i went full on. The carpet was about 3inches thick and although the initial thrust didn't go all the way to the wood, the others made a loud "thunk" sound. The handle started to get a bit slippery, so I stopped the thrust test as I do want to keep my fingers! Remember, the TRIDENT has a sharpened "false edge" at the tip, so I was somewhat hesitant to look at it in fear that it would be damaged. Tip damage? Zero. Plywood? LOTS! I then unwrapped the carpet a bit and slashed a corner off with relative ease. the cut wasn't perfectly straight as the carpet "gave" a bit when struck, so the cut was sorta curved. It did fall to the ground though! Taking the carpet off completely, I then did a few hammer strikes and backfists with the pointy pommel. I went HARD on these, and managed to sink the pommel alomost to the location of the lanyard hole. Slashes, thrusts, pommel strikes...all very comfortable w/ Ceya's TRIDENT!
Now for "utility use". I whittled on a 2 inch diameter Guava stick. Ho hum...The TRIDENT did this with EASE and would make an excellent skinning knife. Taking that same stick, i stuck it in the ground. Placing the TRIDENT's edge on top of the stick, I used another Guava stick to pound that massive "ramp" on the spine of the blade and proceeded to split the stick in half. I then cut carpet again, but in a "normal fashion", cardboards of various density, poly rope...this part was boring as the TRIDENT went right through them all. I was eyeing out that plywood...wanted to throw the TRIDENT but this knife was sent to me for evaluation, not abuse. (Although the TRIDENT is a beefy, thick blade and could've handled it!)
Completion of the live test revealed 0 scratches, 0 tip damage, 0 pommel damage...and the knife was still sharp!? AGAIN, props to DMKnives!
CArry modes were SOB and neck. SOB was VERRRRY comfortable and almost felt pretty good as the width of the sheath supported the small of my back somewhat. Drawing was quick, replacing slow. (Didn't wanna stab myself here, so i wasn't in any hurry to put her back into the sheath!) Standing, running, sitting, driving...SOB was fine.
Necker mode...I thought this wasn't gonna work out, as the blade is pretty hefty. Thought wrong as I wore it under my Class B uniform for about 6 hours tonight! It left no print, and leaning forward, the TRIDENT didn't reveal itself...something I thought it would do. Jumping up and down, off the bench outside the facility, the TRIDENT stayed put. Draw was pretty hard on the ball chain, as it felt like it was gonna bust. Think the hollowed out para would work well here.
ANYWAYZ...again Ceya, I was very HONORED to evaluate this fine TRIDENT WARRIOR of yours! A big mahalo for allowing me to test it live! This part of the eval has TRULY made me a believer in your design. I wa very impressed. Again, from a MBC standpoint, the handle is and worked fine, but to fully appreciate the utility use...a wee bit more handle belly please! No matter which company mass produces the TRIDENT, I am buying one! In fact...I am kinda attached to this proto! LOL! e me please if this is possible!

I have just had a knife made in DC53 by Simon Dalby in the UK. Pictures and comments on his website www.dalbyknives.co.uk
Make no mistake, DC53 from Daido of Japan is way better than D2 - higher hardness, higher toughness, good chipping resistance and superb for grinding. Always double temper after heat treatment.
Supplied in the USA by International Mold Steels where you can also find properties and heat treatment details www.imsteel.com
Good luck
