    Sticky Threads - All The Good Info You Want In One Place

    The stickies have all been condensed into this new super-sticky. This will free up the top of the forum, but make all the good info just a click or two away.

    Each will have its own segment, and all the info is still there.

    Any additional info that you folks think should be added to the stickies can still be added by a moderator. Just send Mark or me a PM with the thread or info that you would like stickied.

    The $50 knife Shop-not recommended
    Great title, but NOT gospel.
    Forging is NOT necessary; file and grind (stock removal)

    "Goop Quench" is Bullsh*t
    Back when they used whale oil, it was still liquid oil
    Use commercial quench oil & match oil speed to steel type;
    Grocery store canola oil works for 1084

    Junkyard steel requires skill and experience to identify and heat treat
    Forget Lawnmower blades and railroad spikes, start with a new known steel
    Good heat treat needs accurate temperature control and full quench
    Proper steel like 1084FG from Aldo is inexpensive and quench in Canola

    Cable damascus is an advanced project has no place in a beginner’s book

    The grinders are the best thing about this book, but 2x72” belt grinders plans are now free on the web

    For the work involved, it is very cheap to buy and use known good steel
    You will spend more money on sandpaper or soda pop than you will for steel

    If you send out for heat treating, you can use
    Oil quenched O1, 1095, 1084
    Or air quenched A2, CM154, ATS34, CPM154, 440C, Elmax plus many others.

    For heat treating yourself with minimal equipment, find Eutectoid steel and quench in Canola oil.

    Suppliers List

    Heat Treating

    You can send blades out for heat treating $10 or $15 for perfect results

    Air Hardening Stainless Steel Only
    Buck Pau Bos -Be sure to check the Shipping and Price tabs

    Oil Hardening Carbon Steels and Air Hardening Stainless Steel (Canadian)


    1095 is a bad choice for a beginner with limited equipment to HT themselves
    1095 is "Hypereutectioid" and needs precise temperature control and proper fast quench oil Like Parks 50 or Houghton K
    Kevin Cashen - 1095 - hypereutectoid steel

    If you are sending one or 2 knives out for heat treatment, use 154-CM or CPM-154 CPM-s35vn Elmax, and ship it out to TKS -Texas Knifemaker Supply
    It's the cheapest way to do 1 or 2 due to minimum charges

    Quenchants for Oil hardening steel
    Forget Goop Quench and Motor oil

    Use commercial quench oil & match oil speed to the steel type
    Explanation and classification oil speeds

    Grocery store canola oil works well -if you use the right steel like 1084

    Brine and water are cheap for "water hardening" steels W1 and 1095, but use fast oils Parks 50 & Houghton Houghto Quench K
    If you use water or brine, expect broken blades

    Hot steel beats plastic, Don't quench in plastic pail

    Glue – Epoxy
    Use new slow setting 30 min high strength epoxy to attach handles and seal out moisture
    Slow epoxy is stronger and gives you time to work
    prep, measure, mix are key in gluing.
    Surface Prep is vital, drill tang holes/ grind a hollow, roughen the surfaces with abrasive or blasting is best
    Ensure the surface is clean including fingerprints, wear vinyl or nitrile gloves
    Use Acetone or Blasting
    Don't over-clamp.A “glue starved joint” is weak

    West Systems G Flex
    Find it locally
    Brownell's Acraglas
    JB Weld-leaves a grey line

    Grinder / Tools

    Hand Tools
    You can do it by hand with files and abrasive like the Green Pete video.
    Use 1084 instead of a file, spheroid annealed steel is butter soft

    A professional three or four wheel 2x72 is worth it
    In my opinion, variable speed and a small wheel attachment are essential on a good grinder.

    KMG Clone Free Plans
    There are some things that need to be modified

    NWG No Weld Grinder $25 plans

    EERF Grinder (EERF =“Free” backwards)

    What Belts to buy?
    Every maker has a preference, new belts come out all the time, search for recent info
    Ceramic, trizact and structured belts are expensive and have long life. Aluminium oxide are cheap and wear quickly
    Some belts have rigid backing, J-flex have soft backing and can blend curves.
    Blaze and Cubitron are popular

    VFD Variable Speed made simple

    Step pulleys are not as cheap as you think
    Maska steel pulleys, plus shaft, bearings, belt

    It all adds up to 1/2 the price of a sealed NEMA 4 VFD like a KB Electronics KBAC-27D

    I like direct drive with no belts, a VFD and 3 phase motor for about $200 over the price of the step pulleys with fine instant control.

    NEMA 1 VFD’s metallic dust intrusion will smoke it.

    3 phase 220v 1.5 HP motor, TEFC, frame 56 or 56C,
    RPM is up to you some use 1700 RPM at double speed.
    Make sure it has a foot base for the KMG and NWG, a C flange face mount for Bader, Bee, Wilton and GIB styles.
    I get them on ebay, even with $100 shipping to Canada I save $ on used motors

    The 1.5 HP combination is the most common
    It allows you to plug into any 110vac, 15 amp outlet.
    A 2 HP motor requires a 220vac input.

    Use the Distributor Locator to find a local source, online sources may be cheaper.

    There are cheaper, but the only VFD I found that runs a 1.5 HP motor on a 110v 15 amp input is the KBAC-27D

    It is NEMA 4 sealed
    Good community and company support, manuals, diagrams, photos and settings.

    Travis W reports running 2 HP on a 110v circuit, but I haven’t tried it.

    Hookup is simple

    Safety Equipment
    Protect -Eyes, Ears, Fingers, and Lungs – remove jewellery and use safety gear.

    Chronic lung disease and cancer really suck the joy out of life.

    If you can't breathe, nothing else matters.

    Wearing a mask and glasses on the top of your head doesn't Count.

    The minimum I use are silicone half masks with P100 Filter
    The soft silicone masks fit better
    3M 7500

    and North 7700

    Use VOC & P100 combo cartridge for acetone and glue fumes.
    Prefilters can snap over the main filter for longer life.

    Here is a short treatise on sharpness from this kitchen knife thread - :

    OK, Let's talk a bit about what makes a good kitchen knife into a superb kitchen knife.

    1)Geometry. Primarily in a kitchen knife this means THIN. Distal taper and a full flat grind usually accompany that.
    2) Edge - Low angle edges and a thin blade behind the edge make the knife cut well. Choppers will be slightly steeper and thicker, of course.
    3) Hardness - The blade on a kitchen knife is usually a bit harder than a general use knife. This will allow the edge to last longer by being more resistant to wearing away by abrasion.
    4) Toughness - Not to be confused with hardness, the steel needs the ability to resist the edge breaking down.
    5) Matching the steel to the task.
    ............A Sashimi blade like a 180mm long yanagi-ba can be very hard and have a very low edge angle. All it ever should do is cut in a straight slicing line against clean and soft tissue. The finest grain and highest practical working hardness are key steel choice considerations.
    ............A 100mm veggie cutter will have a slightly less acute edge, and be not as hard. It will be used to push cut ( chop) firmer and dirtier cellulose based objects.Moderate toughness and medium hardness are the steel parameters here.
    ............A 60mm paring blade will be even less hard, less acutely edged, and made from a steel that takes more lateral force ( tougher). These knives are turned in use, and cut a variety of objects.

    All the above except geometry are a product of steel choice and HT.

    The place where most people go wrong is thinking hardness equals sharpness.
    Sharpness is just a function of how finely angled we can make the edge bevel. If you draw a huge sketch of the blade edge, you will see the apex as a single point. This is the theoretical edge. In reality, the edge is back a bit from there. The size of the steel grains and the carbides will make the theoretical edge impossible to attain. Tougher steels usually have larger grains, and large super hard carbides. Harder steels have a composition that allows for hard martensite to form, but too much hardness will allow the thin edge to chip away, leaving a microscopically ragged edge. Grain size will also limit how fine the edge can be. The perfect kitchen knife steel would be hard and tough. Choosing the alloy to meet the task is part of this, and HT is the other half.

    Lets make some imaginary blades.
    A) - This blade is made from bricks. Each brick is tightly mortared to the next. When we sharpen the blade, we needed to use a lot of effort to knock off bricks until we have a stair step to the edge where it is only one brick wide. This blade will cut a bit rough because of the stair step sides, and no mater what we do, the edge can only be one brick wide. This blade will be very tough, but not all that sharp.
    B) - This blade is made from concrete. The mix is small rocks and fine cement. The rocks are held in place by the surrounding cement. Sharpening will wear away the rocks at the edge pretty fast, and with some work and stopping we can get the cement worn down to an edge much thinner than the brick blade. However, the small rocks at the edge will pull out in use fairly easily, leaving the edge irregular. It will be sharper, but not as tough as the brick blade. The edge is still limited to the size of the rocks.
    C) - This blade is made out of cement. It is a mix of fine sand and Portland cement. Each grain of sand is bonded to the next by the Portland in a strong bond. This blade will be harder to abrade, but will also sharpen down to an edge that is as fine as a single grain of sand. Because all the sand grains are about the same size, they wear away slowly and evenly. This will be a hard and tough blade.

    All will get sharp, and cut your imaginary fingers easily. So how do you decide what steel to use?

    Blade A is like one made from a very hard and tough steel. A blade made in a steel that has large carbides, and/or large grain structure is like this. D-2, and other super wear resistant steels are often picked for this reason....They make great knives.....but it will not make the best kitchen blade.
    Blade B is like most regular knife steel having a bit of alloy. The carbides are moderately sized, and the grain can be made fairly fine. CPM steels also help keep the grain size reasonably small and distribute the alloy evenly.. These knives will be good performers, and make up the bulk of good kitchen knives. They can be hardened a bit harder.
    52100, CPM-S35VN, 440C, etc.
    Blade C is made from a steel that has no extra alloying to make larger carbides, The grain structure is very fine. These knives can be hardened very hard and the edge will still hold up with the right edge geometry and proper use. AEBL, 1095, W2, and some of the very pure Hitachi steels are in this class. With some real careful HT and testing, 52100 can be brought here, too. These steels have the toughness to hang on to the martensite grains and carbides while still being hard and resisting abrasion. The main reason one maker gets superb results from these steels and another doesn't is almost always in the HT.

    Warpage !
    There are many ways to straighten warpage. The best way is to prevent it from happening.

    1) Grind evenly.
    Forge evenly.
    Avoid sudden shifts from thick to thin. Have even tapers and bevels

    2) Stress relieve the steel before Heat Treatment. (Actually, stress relief is part of heat treatment).
    There are several methods of cycling steel to get a fine grain and evenly distributed carbides, but simple methods will also relieve stress.
    Sub-critical annealing is the simplest. Heat the steel to 1200°F and hold for two hours. Cool at 100° per hour to 800°F and then quench (or let air cool) to room temp.
    For any steel, stainless, hypo, or hyper will remove any stresses in the steel.

    Here is metes method recommendations for stainless steels:

    When you get the steel do a subcritical anneal ,1200 F for two hours. Straighten if necessary.
    Grind etc then another subcritical anneal for 2 hours
    Quench , if in oil agitate spine to edge. Air hardening steel can be quenched in plates using 3/4 to 1" aluminum.

    If you attempt to straighten a hardened knife heat to at least 400 F !

    Japanese Blade info:

    These are some basic terms ( there are probably 100 more words, but these will cover most all major areas):

    ha - the hardened edge of the blade
    ji - the surface between the hamon and the shinogi
    habuchi - the line between the hamon and the ji ( AKA nioi-guchi)
    hamon - the line indicating the border of the hardened edge. This is a group of crystals ( nie and nioi) that form in the hardening process.
    ashi - lines of nioi extending from the hamon toward the edge
    nie - small visible martensite crystals. Often seen as bright specks and little "islands" just above the hamon.
    nioi - minute/microscopic martensite crystals visible in a groug as a milky/wispy cloud.
    shinogi - the ridge line of the blade
    shinogi ji - the surface between the shinogi and the mune
    mune - the spine of the blade

    Blade parts ( very simplified):
    Top/spine - mune
    edge - ha
    tip - kissaki
    tang - nakago
    handle - tsuka
    guard - tsuba
    Blade collar that guard rests on - habaki
    shoulders habaki and tsuba rests on - machi
    where the tip and edge meet - yokote
    where the bevels meet - shinogi
    curvature of blade - sori
    fuller on blade - bohi
    blade length - nagasa
    sheath - saya

    Here are some sites that will give a lot of info. The first link will give you dozens of great sources for reference and research. It can take a year to absorb that site alone. (this site has links to most any question about japanese swords and such)

    This is great for figuring out Japanese kitchen knife terms and names;

    Difference between a hamon and a temper line:

    When the steel is quenched fast enough to pass the pearlite nose, the structure remains austenite ( too slow and it becomes pearlite at 900F). As it cools on down and reaches around 400F, it suddenly starts converting to martensite ( the Ms). When the temp has dropped to about 100-200F this conversion is finished on carbon steels (Mf). The structure is now an untempered martensite called "brittle martensite". Anyone who has tried to straighten a blade at room temp right after the quench knows why it is called that

    The first temper tempers this into "tempered martensite", which has a structure a tad like pearlite...and thus is much tougher. When the first temper was done, there was also a small amount of retained austenite that never converted in the initial quench. During the rise to 400F and cooling in the first temper, it converts to martensite. The cooling from temper should be rapid and done in room temp or cooler water. This assures the retained austenite converts (slow cooling from 400 between tempers may help stabilize the RA). This new martensite is still brittle, and the second temper converts and toughens it. A blade with only one temper won't snap in half, but the edge may be chippier. Tempers should be at 400F or higher, and there needs to be two. One hour each is sufficient for carbon steels.

    During temper, the steel needs to rise back to the Ms to make the changes it needs. Tempering below that will relieve most of the stress, but the blade isn't fully tempered....and thus still has some brittleness. Some people think they are getting a harder blade by staying below the Ms, and tempering at 325-350, even 375F. The thing they don't know is that the hardness isn't appreciably dropped until the Ms is reached. A temper at 350 and one at 425 may only be one or two Rc points apart.

    A hamon is the junction of structures mixing pearlite and martensite. There will be wisps or one or the other going both ways, and pockets or dots of hard martensite crystals in the pearlite matrix. The old name for this mix was troosite. A hamon forms when the entire blade is heated to the austenitization point, and the the entire blade is cooled in quench. What forms the hamon is the cooling is varied in some areas due to clay and/or blade thickness.

    A temper line is more properly called a quench line, and is a line of demarcation where the heating and cooling has separated the hardened area from the unhardened area. They are normally formed in an edge quenched blade. Quench/Temper lines will be pretty much straight, as they form along the radiated heat border between two temperature ranges. A quench/temper line forms when the pearlitic blade is heated to austenitization only along the edge. It gets its "temper" name from the older method of tempering where the "temper line" was walked down the blade from the spine by gently heating the spine with a torch or hot piece of steel. This line was stopped when it got about 1/3 away from the edge. The resulting temper colors on the blade had a similar look as the line formed in edge quenching. However, a quench line is deeper into the steel, and the temper colors are only on the surface.

    A hamon will vary a lot depending on how fast the martensite forms and how much rapid cooling happens above the hamon. A temper line varies almost none....just a darker line.
