We partnered with Paragon oven to design and produce a low cost, good quality knife makers oven.
- This oven has a chamber 14” deep, 8” wide and 4” tall.
- The overall size of the oven is 14” wide, 25” deep and 15.5” tall.
- Maximum Temperature on this oven is 2200F. A typical K thermocouple is located on the center back wall of the chamber.
- Side swing door on heavy duty hinge.
- NEMA 6-15P 15amp 250v plug. You may need to change this plug to match your 240volt outlet.
- Electrical requirements are: 1 phase, 240volt and 9amps.
- Coils are standard Paragon and we will carry replacements.
- Fused circuit.
- Weight is 70lbs
The temperature controller is an infinite dial just like your kitchen oven. Use the large pyrometer temperature gauge (displays in both Fahrenheit and Centigrade) on the front of the oven to get to your temperature just like you would using the oven in your kitchen. The minimal electronics in this unit help keep the cost down.
Don’t think we skimped on quality though. The oven has a heavy gauge steel wrapper around 2.5” thick firebricks. We minimized the electronics, not the quality of the unit. A high temp. paint in KnifeDogs orange provides a durable finish.
Shipping weight is 80lbs so this can ship via UPS. Currently we are shipping only to the USA. (International customers, if you have a freight forwarder that you have experience with we can work with you.)
This low cost unit will allow the knife maker on a budget to heat treat most any steel out there.
When starting out with this oven, take time to identify where the dial controller will need to be positioned to achieve the temperature you want. With just a bit of trial and error, you will be able to walk right into your desired temperature. Your oven will cycle on and off to maintain that temperature just like the oven in your kitchen or a toaster oven so many makers use to temper knives. Expect 25F to 40F variance in the temperature you dial in. We have designed this oven for the knife maker on a budget or the knife maker that is into production and needs a tempering oven while using their more expensive digital oven for heat treating.
Why not just use a toaster oven for tempering? You can and many guys do. The issue with toaster ovens is there is no mass to hold the heat to moderate the temperature changes as it heats and cools around your target temperature. The size also is an issue. You want to be a couple inches away from the heat source. The elements are going to be a couple thousand degrees as they heat up. Heat treating ovens work by heating "full blast" until the target temperature is reached and then they cycle off. (some high end digital controller ovens operate differently). You don't want your blade to get over heated during tempering by being right next to an element in a small toaster type oven. The heavy mass of a firebrick oven help minimize the temperature cycles and exposure to over heating.
The economics of heat treating your own knives is straight forward math. If you are producing 20 knives a year and send them out for heat treating at $15 a knife, your annual cost is $300. The straight math doesn’t tell the whole story though. When you have your own oven, your production will go up and your turn around time will drop by several weeks. Caution: This oven, like nearly all heat treating ovens, has exposed heating elements. Turn off the oven before adding or removing any material. Accidentally touching your metal knife to an electrically charged oven element will give serious shock and may cause death.paraovenship
