Double Barrel& KM-SeriesFurnaces forKnife MakersThe spirit of agreat knife

Great knives helped carve out the wil-derness, fight wars, save lives. Explorershave carried them to distant lands. Kniveshave earned their place in history.

Great knives are more than steel andornament. They contain a spirit thatmakes them feel as an extension of theuser’s hand. Touch a great knife, and itfeels alive. As the knife ages, its spirit re-mains as vibrant as the day the maker gavethe knife to the world. The spirit in theirknives lives on long after the mastercraftsmen who made them.

Wherever humans have withstood se-vere tests—whether in the steaming jun-gles of the South Pacific, the burningdesert of Africa, or the cold, blowingwastelands of Korea—they have de-pended upon great knives. Wherever ex-plorers have gone, they have taken greatknives with them—over the prairies andmountains of the American west, acrossthe desolate plains of the North Pole,through the silence of deep space.

Upon their return home, these explor-ers and soldiers and medics and astro-nauts have numbered among their mostpriceless possessions their knives. Whenthe owner touches his knife, memoriesawaken. Once again he hears the storiesaround the campfire; he smells the pineneedles in the wilderness. He remembersthe lean-tos he fashioned; the kindling hemade for a fire in a blowing snow-storm.His heart quickens its pace a few beats ashe sees scenes he shared with the knife.

Some of these knives find their placeson mantles and in display cases. Othersare passed on to sons and daughters tocontinue their faithful service.

Not all great knives face extreme tests.Some are carried into combat and rarelyused. Others see no more action than acamping trip. Yet each bears the imprintof its maker. Each contains a spirit thatmakes it feel alive to the touch. Each ex-tends a secure feeling that comes fromwearing a knife you can depend on. Themaker, immersed in the dust and sweat ofhis work, sends a part of himself with eachknife that leaves his shop. He lives on inhis knives.

Knife making is an adventure all itsown. It begins when the future ownershares the dream of a special knife withthe maker. They talk excitedly over thefirst rough sketches. Then the maker re-tires to his shop and loses himself in the

creation of the knife. Time disappears; thehours tick by as he grinds, heat treats, pol-ishes.

Test exotic heattreating formulas

When your Paragon KM- or HT-seriesfurnace arrives, you will begin to live theadventure more fully. Now you can jointhat elite corps of knife makers who wit-ness the birth of the knife. In the bright redheat of the furnace, the soul of the knife isborn.

Many furnace owners revel in testing.They put blades through tests more severethan any knife owner would dare. Theytest for Rockwell hardness, but they don’tstop there. They count the number of cutsa knife makes on hemp rope. They mea-sure the foot pounds of torque required tobend the blade to 45° or even 90°. Thenthey straighten the blade, slap on a handleand test it in the real world.

The knife maker with a Paragon fur-nace can try exotic heat treating methodsat his leisure. Does quenching in dry iceimprove blade performance? What hap-pens when 52100 steel is triple-quenchedwith a one-day wait between eachquench? After this treatment, will a 52100blade bend to 90° without chipping? Whatif you freeze the steel between quenches?

With a Paragon furnace in your shop,all questions about heat treating formulasare settled. You find out for yourself whatworks and what doesn’t. Testing and heattreating are at the heart of the knife mak-ing adventure. Here is where your confi-dence as a knife maker takes root.

A bond of trustThe knife maker’s credo is simple: to

create a knife that represents the knifemaker himself. Quality of work is not justa fad for him. It is a passion. Anything lessthan one’s best is unthinkable.

The buyer of a custom knife appreci-ates fine detail. He or she marvels at thelines and curves the maker coaxed fromthe steel with such patience. There is abond of trust between the owner of a fineknife and its maker. This is why the knifemaker sleeps better when he controls everystep in creating a knife.

The knife maker derives joy from work-ing with his hands. He makes knives thatare not merely prized, but treasured.When the knife owner wipes a rag acrosssuch a knife, he is caressing it as much ascleaning it. Part of this spirit of knife mak-

Paragon Furnaces for theKnife Maker and Heat

TreaterShown is the KM-36T.The KM-14T, KM-18T,KM-24T, KM-36T, andKM-45T furnaces lookthe same from thefront. The chief differ-ence between thesemodels is length.

Order your KM-series, Xpress-KM-series, Double Bar-rel, or PKM-9D with a side-swing door or the dropdoor. The KM-18T above has the side-swing door.(The furnace price is the same for either door.) The soul of the blade is

ing is lost when you send the blade out forheat treating and await its return.

Every time you, the maker, release oneof your knives to the world, your reputa-tion goes with it. This is why makers feelcompelled to control every step in theblade’s journey from initial designthrough final polishing.

No more waitingA Paragon furnace sets the knife maker

free. No more wrapping blades and ship-ping them to your heat treater. No morewaiting until you have a dozen blades toget the best price on heat treating. Nomore turning away orders for last-minutegifts.

While your furnace is hardening andtempering blades, you can busy yourselfgrinding more knives or fitting handles.After you’ve used your Paragon furnaceawhile, you will wonder how you ever gotalong without it.

When asked to make a knife on shortnotice—whether for a Marine Corpsawards presentation or an archaeologiston his way to Africa—you will be ready.When a custom knife is needed as a goingaway gift, and the recipient is leaving inthree days, you will be ready. Your furnacemight even pay for itself on rush ordersyou would otherwise have missed.

Own a furnace and you alone decidewhen you will complete a knife. If you stayup one Friday grinding a knife, you can

heat treat it that evening and deliver it Sat-urday morning—just in time for a gratefulwife to present to her husband on hisbirthday.

Finishing a knife whenever you wantwill excite you. You will find yourselfworking into the night to complete a newdesign. When you send the blade out forheat treating, the excitement of making itis forgotten. By the time the blade returns,you hardly remember it.

Ed Fowler and hisParagon KM-14D

Ed Fowler has been making knives offand on since the sixth grade. Ed believesheat treating is a crucial step in makingknives. The soul of the knife is born in thefurnace. To entrust heat treating to some-one else would be unthinkable to EdFowler.

“Knives are my life,” says Ed. Owninga Paragon furnace adds magic to the ad-venture, because the knives come alive in-side the furnace.

With a Paragon furnace, the knifemaker can deepen his knowledge of work-ing knives. Experimenting with heat treat-ing teaches the knife maker more aboutthe steels he cherishes than any book orteacher could. With his own furnace, hecan alter the heat treating formula to ex-actly fit his own knives, just like Ed Fowlerdoes.

“I couldn’t achieve the control I nowenjoy had I not had a Paragon furnace,”Ed Fowler says. “Owning a Paragon is ex-

tremely beneficial toblade smithing.” Edfound his furnacehelpful in discoveringsome of the ideas inhis classic books,“Knife Talk: The Art and Science ofKnifemaking” and “Knife Talk II: TheHigh Performance Blade.”

“Paragon offered me no financial re-wards or free equipment for this endorse-ment,” Ed said. “I recommend Paragonfurnaces because they make an excellent,reliable product.”

A full range ofknifemaking furnaces

Our knife making and gunsmith fur-naces come in a wide range of interiorsizes. (See chart below.) Even if most ofyour knives would fit inside the KM-14T,you may be happier with the KM-24T, themost popular size. Too much capacitymay be better than too little. After all, itdoesn’t hurt to heat shorter blades in thelonger KM-24T; electrical consumption isminimal. Our KM-18T is mid-way inlength between the KM-14T and KM-24Tso you can buy just the size you need.

Choose a side-swingdoor or a drop door

Order your KM-series, Xpress-KM-se-ries, Double Barrel, or PKM-9D with aside-swing door or the drop door. Thefurnace price is the same for either door.

The Double Barrel 18furnace for gunsmiths

The Paragon Double Barrel is just theright size for heat treating knives and casehardening gun parts. Experiment withcolor case hardening. Restore the fadedcolors of old guns. As with the other Para-gon furnaces, the Double Barrel 18 and 24have a digital controller so you can pro-gram the temperature and hold time. Thecontroller eliminates guesswork—insteadof estimating a temperature by the colorof the heat, just enter temperature. Youwill no longer have to adjust a switch tomaintain the hold time for case hardening;the controller does it for you. Set the holdtime for as long as necessary (typicallytwo hours).

Your choice of threedigital controllers

Now you can choose the controllerthat fits your budget. You will marvel atthe accuracy and repeatability of digitaltemperature control.

The Sentry 12-key controller is fasterto program and has more features thanthe Sentry Xpress 3-key controller. How-ever, the Sentry Xpress is more economi-cally priced. The Sentinel Touch Screen,our newest controller, offers advancedgraphics and wifi monitoring.

PKM- andHT-seriesHeat TreatingFurnaces

The KM-series furnaces are long andnarrow, ideal for knives. The PKM- andHT-series are sized for general heat treat-ing. (We also design custom furnaces.)

Machine shops save time with a fur-nace at their disposal in their own shop.You will no longer send a die out for heattreating, wait for its return and then sendit out again for additional heat treating.

The PKM-9D, our smallest stan-dard-order furnace, measures 8 ½” wide,4 ½” high and 9” deep inside. ThePKM-9D is small, but powerful. It willreach 1850° F. within 45 minutes. TheHT-10D and PKM-9D fire on a 120 volt,15 amp circuit. The PKM-9D can beshipped by UPS.

The HT-10D interior measures 8 ½”wide, 8 ¾” high, and 9” deep, a good sizefor most small parts. The HT-14D ismade for large objects and higher volumeusers. The firing chamber is a generous13” wide, 8 ¾” high and 13 ½” deep. TheHT-14D operates on a 240 volt, 20 amp.circuit.

The HT-22D offers capacity that ishard to believe for the price. Costing onlyslightly more than our smaller furnaces,the HT-22D measures a massive 21” wide,13 ¼” high and 21” deep inside.

Advantagesof a ParagonFurnaceSolid construction� The drop door swings open with

one-handed operation. A coun-ter-weight handle holds the door se-curely closed.

� The swing and drop doors are mountedon a heavy-duty hinge shaft for smoothopening. Because of the rigid case andheavy hinge, the door is sturdy enoughfor years of faithful service.

� To prevent shock hazard, a micro safetyswitch automatically shuts off power tothe elements when the door is opened,yet the temperature controller remainspowered.

� A chain holds the drop door open andout of the way. If you prefer, you canorder a swing door at no extra charge.

� The elements are mounted in dropped,recessed grooves machined into thefirebrick. The grooves protect the ele-ment for long life and low maintenance.

Elements are simple to replace becausethey’re exposed rather than embedded.You can thread new elements into placefollowing the manual.

� The thermocouple wire is kept insidethe control box for protection from theharsh environment of the typicalbladesmith shop.

� The firing chamber is protected by arigid, deluxe steel case. A built-in standlifts the firing chamber safely off yourwork table.

� We use high temperature wire in theswitch box for long life.

� Made in America. We are very proud ofour master craftsmen and women.

In business since 1948Paragon Industries, L.P. is one of the

oldest and most widely recognized kilnand furnace manufacturers in the world.Paragon was founded in 1948 and is aleader in electric kilns and furnaces. In de-signing heat treating furnaces, we useideas that have been proven in Paragonkilns and furnaces since 1948. Many of theParagon kilns manufactured twenty andthirty years ago are still firing.

AccessoriesKnifemaker’s HeatTreating Kit

Contains 1 pair hot gloves, 1 heattreating fork, 4 knifeholders, and 8 fire-brick supports.

Hot GlovesFor intermittent handling of hot ob-

jects up to 400° F. Sold in pairs. Not in-tended for handling hot blades.

Heat Treating ForkEasily removes knifeholders and blades

from the hot furnace. A sliding woodenhandle allows you the most comfortableposition for holding the fork. 31” long.

Firebrick SupportsPosition firebrick supports under the

knifeholders inside the furnace. The fire-

brick supports raise the knifeholders soyou can slide the fork under holders.

KnifeholderHigh temperature removable pins fit

into holes pressed into a ceramic base.The pins hold the foil-wrapped blades onedge so heat can circulate around eachblade.

Gas Injection Flow Meter

Oxygen in the furnace forms a scale onthe surface of knifeblades and other partsduring heat treating. To avoid surfacescale, wrap the parts in heat treating foilor inject an inert gas into the furnace. Thegas displaces the oxygen.

Please note that the gas may reduceheating element life. Also, gas injectiondoes not offer better results than heattreating foil nor does gas injection preventall scaling. The main benefit of gas injec-tion is the savings in time over wrappingthe steel in foil.

The flow meter can be ordered with anoptional solenoid kit, which enables youto turn the gas on or off for each segment,or stage, of the firing. The solenoid kitmust be ordered with the 12-key control-ler. Program the controller to turn on thegas at temperatures where carbon beginsto form on the tool steel.

In addition to the flow meter, you willalso need a regulator to reduce the pres-sure from the gas tank.

The flow meter can be installed at thefactory or is available as an after-marketaccessory.
