KF518DThe Paragon KM18 Double Barrel is a wider, taller version of the standard KM18—offering greater chamber volume while keeping the same depth. Designed specifically for bladesmiths who need more interior space for larger knives, sword blanks, or multiple items per batch, this model provides serious capability in a compact, firebrick-insulated package.
Owning a kiln gives you full control over your heat treating process—crucial when working with high-performance steels. Whether you're developing your own tempering schedules or perfecting blade hardness through normalization, quenching, and annealing, the KM18 Double Barrel puts consistent results at your fingertips. No outsourcing, no delays—just reliable, professional-quality heat treating from your own shop.
The KM18 Double Barrel offers a spacious interior. This expanded chamber allows for larger or wider blades, as well as increased batch sizes. Like all KM Series base models, the KM18 Double Barrel uses durable 3" firebrick insulation and is equipped with a single-zone temperature control system.
It comes standard with a drop-down door, which serves as a convenient loading shelf. The SENTINEL Touch Xpress digital controller gives you complete programming flexibility and easy operation, whether you're running basic or complex heat treating cycles. A solid-state relay ensures quiet, precise power regulation with longer service life. The door switch automatically disables power when open for added safety.
The KM18 Double Barrel is a great fit for serious hobbyists and professional knifemakers who regularly work with wider blades or who prefer batch processing. It's also ideal for those working with sculptural tools, dies, or bushcraft blades that don’t fit well in narrower chambers. If you've outgrown your current kiln’s capacity or simply want more flexibility in what you can heat treat, this model is a strong upgrade.
