Paragon KM-14T Knife Maker’s Heat Treating Furnace

Great knives helped carve out the wilderness, fight wars, and save lives. Explorers have carried them to distant lands. Knives have earned their place in history. At Paragon we are excited that knives heat treated in the KM-14T are making history right now. The KM-14T was our first knifemaking furnace. We introduced it in 1986 with an advertisement in Blade magazine. The KM-14T has the full 12-key Sentry controller. Also available is the Xpress-KM-14 with the economical 3-key Sentry Xpress controller and the Sentinel Smart Touch.

Test exotic heat treating formulas

When you own a Paragon knife heat treat oven, you can live the knife making adventure to the fullest. You will actually witness the birth of your blades in the bright red heat of the 120-volt knife furnace.

Many knifemakers enjoy owning a knife forging furnace, because they can revel in testing their favorite steels. They put blades through tests more severe than any knife owner would dare. Yes, they test for Rockwell hardness, but they don’t stop there. They test the knife against hemp rope and 2x4s. How long will the blade remain sharp? They bend the blade to 45° or even 90°. Then they straighten the blade, slap on a handle and test it in the real world.

The knife maker with a KM-series Paragon knife heat treat oven can try exotic heat treating methods at his leisure. Does quenching in dry ice improve blade performance? What happens when 52100 steel is triple-quenched with a one-day wait between each quench? After this treatment, will the blade bend to 90° without chipping?

With a Paragon 120-volt knife furnace in your shop, all questions about heat treating formulas are finally settled. It is no longer only theory. You find out for yourself what works. Testing and heat treating are at the heart of the knife making adventure. Here is where your confidence as a knife maker takes root. Experiment with differential hardening, an ancient bladesmith technique. Try out the newest tool steels. Are they really as good as the tried and true D2 and A2?

New higher furnace temperatures

This Paragon knife heat treat oven is now rated to 2350 degrees F, so you can heat treat as hot as you need to.

Choose a side swing door or a drop door

You can order a Paragon knifemaking furnace with either a drop door or a side-swing door. (The photo above shows the traditional drop door. Scroll down to Options to see the side swing door.) The price of the 120-volt knife furnace is the same with either door style.

The drop door opens downward with one-handed operation. A counter-weight handle holds the door securely closed. The door, whether drop or side-swing, is mounted on a heavy-duty 1/2” thick hinge shaft for smooth opening. Because of the rigid case and heavy hinge, the door is sturdy enough for years of faithful service.

Door safety switch

The door micro safety switch shuts off the power to the elements when the door is opened, yet the controller continues to give a temperature readout. The safety switch is standard on the KM series Paragon knife heat treat ovens.

Choose from the optional paint colors

As shown in the photos, the standard 120-volt knife furnaces are painted a deep black, which would look perfect in your shop. You can choose a different paint color at no extra charge. (Choose from the paint colors listed below the furnace specifications. Scroll down.)

A bond of trust between you and the knife owner

The knife maker’s credo is to create a knife that represents the knife maker himself. Quality of work is not just a fad for him. It is a passion. Anything less than one’s best is unthinkable. You are creating knives for people who can appreciate craftsmanship.

The buyer of a custom knife can see fine detail. He or she marvels at the lines and curves the maker coaxed from the steel with such patience. The custom knife maker appreciates the difference between high-carbon steels such as D2 and lower-grade steels used in the mass market. There is a bond of trust between the owner of a fine knife and you, its maker. This is why the knife maker sleeps better when he controls every step in creating a knife.

The knife maker derives joy from working with his hands. He makes knives that are not merely prized, but treasured. When the knife owner wipes a rag across such a knife, he is caressing as much as cleaning it. Part of this spirit of knife making is lost when you send the blade out for heat treating and await its return. Every time you, the maker, release one of your knives to the world, your reputation goes with it. This is why makers feel compelled to control every step in the blade’s journey from initial design through final polishing.

No more waiting for commercial heat treating

A Paragon KM-series 120-volt knife furnace sets you, the knife maker, free. No more wrapping blades and shipping them to your heat treater. No more waiting until you have a dozen blades to get the best price on heat treating. No more turning away orders for last-minute gifts.

While your 120-volt knife furnace is hardening and tempering blades, you can busy yourself grinding more knives or fitting handles. After you’ve used your Paragon knife heat treat oven awhile, you will wonder how you ever got along without it. When asked to make a knife on short notice—whether for a Marine Corps awards presentation, a soldier’s pre-deployment farewell sendoff, or an archaeologist on his way to Africa—you will be ready. When a custom knife is needed as a going away gift, and the recipient is leaving in three days, you will be ready. Your KM-series furnace might even pay for itself on rush orders you would otherwise have missed.

Own a furnace and you alone decide when you will complete a knife. If you stay up one Friday grinding a knife, you can heat treat it that evening and deliver it Saturday morning. Just in time for a grateful wife to present to her husband on his birthday.

Finishing a knife whenever you want will excite you. You will find yourself working into the night to complete a new design. On the other hand, when you send the blade out for heat treating, the excitement of making it is forgotten. By the time the blade returns, you hardly remember it.

Even if most of your knives would fit inside the KM-14T, you may ultimately be happier with the KM-24T, a popular size. Too much capacity may be better than too little. After all, it doesn’t hurt to heat shorter blades in the longer KM-24T; electrical consumption is minimal. Our newest KM-18T is mid-way in length between the KM-14T and KM-24T so you can buy just the right size for your needs.

Solid furnace construction

The furnace is insulated with 3” thick refractory firebrick, which is 1/2” thicker than the standard. The elements are mounted in dropped, recessed grooves machined into the firebrick. This groove protects the element for long life and low maintenance. Elements are simple to replace because they can be lifted directly from the groove. You can replace elements following instructions in the printed manual. The firing chamber is protected by a rigid steel case. A built-in solid stand lifts the firing chamber safely off your worktable. The thermocouple wire is kept inside the control box for protection from the harsh environment of the typical bladesmith shop.

Printed instruction manuals

Your furnace includes a wiring diagram, a controller instruction manual, and a heat treating manual with heat treating instructions for D2, 440C, ATS 34 and 154 CM. The manuals are written in plain English for the beginner.

Made in America

All Paragon furnaces are made in Mesquite, Texas USA. We are proud to support the American worker.

Optional gas injection flow meter

During heat treating, scale forms on the steel. You can eliminate most scaling by wrapping the blades in stainless steel foil. Or you can install the gas injection flow meter on your furnace. It is available as either an add-on kit, or you can order the furnace with the meter installed. The meter regulates the flow of an inert gas, such as argon, inside the furnace. The gas displaces the oxygen to prevent some of the scaling.

The knifemaking kit

In addition to the furnace, you will need a knifemaking kit, which separates the blades and holds them parallel inside the furnace. Please click the link below in the Options section.

Thermocouple with “special limit” wire

The thermocouple senses temperature inside the kiln. It is the small rod that extends into the firing chamber. The ¼” wide Type-K, 14-gauge, exposed-tip thermocouple is made with special-limit wire for superior accuracy. The exposed tip gives the controller a fast response time for even temperatures during holds. The thermocouple is made in America to our exacting standards.

Designed for production

Paragon’s warranty is not affected by frequency of use. Fire your new kiln every day if you want, even in commercial settings. That will have no effect on the warranty period.

The Optional Knifemaking Kit

In addition to the furnace, you will need a Knife-making Kit, which separates the blades and holds them parallel inside the furnace.
