Hot Shot HS18K Knife Makers Kiln
Designed with knife makers and blacksmiths in mind, the Hot Shot HS18K combines precise heat control, safety features, and a compact footprint for shop-floor heat treating. The 18" deep chamber accommodates longer blades from tip to tang, while side-mounted heating elements deliver even temperatures across the load. A dual-layer Cool-Touch exterior keeps the outer surface cool to the touch, and the full swing door enables safe, one-handed loading and unloading.

Performance Details
The 120V model reaches 2000°F in about 50 minutes and 2200°F in roughly 1 hour 40 minutes. The 240V version achieves 2200°F in about 30 minutes, enabling faster processing of batches or multiple blades in a session.
What You Can Do with the HS18K
Heat treat knives and tools with confidence, including hardening, tempering, annealing, and knife-making cycles. The even heat distribution supports consistent blade hardness and edge retention, while the safety features reduce risk during long cycles.
Optional Accessories
- Argon Gas Kit: Includes tubing, fittings, and a ceramic needle for argon connection to reduce surface oxidation during annealing or brazing
- Rolling Stand with Locking Casters: Includes middle shelf and mobility; upgradable to 2 shelves
- Quench Tank: 3-gallon welded steel tank (24" deep × 26" tall) with bolt-on feet, steel lid, and welded handles for easy transport
