Product Overview

HotShot HS-18K

Experience the epitome of precision, safety, and reliability with the Hot Shot 18K, an oven crafted in collaboration with esteemed blacksmiths and knife makers. Get your perfect blade and be safe every time you turn on your oven with our cool-to-touch, side elements and long chamber (18”). We know most knife makers are hobbyists working out of their own shop or garage so we designed an oven that was cool to the touch, a removable door for easy access in and out and all of the essentials built in with no added up charge; solid state relay, cooling fans, alarm and door switch.

The side elements allow for even heat distribution throughout the oven so you never have to worry about hot or cold spots! The icing on the cake…. our oven gets up to temp fast! The 120V option gets up to 2000F in 50 minutes and the 240V option in 25 minutes! Wow! Add on an Argon Gas Kit to help eliminate scaling on the surface of the steel!

The Perfect Oven For Knife Making
Heat treating knives is done to harden the steel for sufficient use and to not cause any damage or weakness to the knife. Owning your own oven allows you to heat treat on your time and not have to wait for the heat treating facility.

What is heat treating?

Heat treating can improve the strength, durability and reduce wear on material. It is the process of heating metal to a certain temperature, ramping the temperature(s) at a certain rate of time, soaking or holding it at the temperature(s) and then cooling it.

Why heat treat?

The purpose of heat treating is to bring steel to a hardened state. The correct hardness depends on the application of the steel being treated.

Why would I want my own oven to heat treat?

The main reason you would want to do your own heat treating is to save time and money. Heat treating facilities can often be backed up, expensive and require certain size batches of material to be done at one time. Heat treating knives allows the knife to get to a hardness level that will not cause the knife to bend, get damaged or cause any weak parts.

Constructed to last

Hotshot ovens are specifically designed with the end user in mind. Hot Shot ovens feature a full swing side opening door to allow safe and easy insertion and removal of material as well as a cool-to-touch one-handed handle made from high-quality stainless steel for easy opening and closing. 

Hot Shot ovens are constructed with a high-quality powder-coated shell. The high-density fiber insulation in a Hot Shot oven is machined to high tolerance specifications so that each piece fits perfectly together to provide a proper seal, ensuring that it will maintain its temperature and work efficiently to prevent loss of heat. Each oven comes with a removable high-density floor. This is ideal to assist with project setup or if it needs to be replaced.

Hot Shot uses Kanthal A1 heating elements, a type K thermocouple and every oven comes standard with a solid state relay at no additional charge.


Advanced Features
Solid State Relay

Unlike many other ovens & kilns all Hot Shot ovens come standard with a solid state relay. Having a solid state relay eliminates the distractive clicking noise that a mechanical relay makes. A solid state relay is also more dependable and provides a longer life expectancy than that of a mechanical relay.

Programmable Alarm

Each unit comes standard with an integrated alarm that can be set to alert the user when a desired point or temperature is reached in the program.

Safety Door Switch
We also have integrated a safety door switch that will de-energize the heating
element when the door is open.

Argon Gas Inlet Flow Meter Kit (Optional)

Argon is usually delivered at dew point less than -75°F with an oxygen content below 20 ppm. This gas provides an inert atmosphere and is suitable for a variety of heat treatment processes.

Annealing (non-ferrous metals, stainless steel, and alloy steel)
Hot Shot offers this well-designed and easily adaptable Argon kit for all your heat-treating needs. Includes flow meter, tubing, fittings and ceramic dispensing needle.
