Na Grani On The Edge Stainless Steel HMD

The Na Grani On The Edge is a one-piece stainless steel heat management device machined from AISI 304 food-grade steel — significantly more durable and heat-capable than the aluminium HMDs most people are familiar with. The open-top design gives you direct access to your coals for quick adjustments, and the 74 mm contact diameter fits most phunnel bowls on the market. Built in Russia, ships in a branded wooden presentation box.

Na Grani On The Edge Stainless HMD — 74 mm, AISI 304, Open-Top

Why This Heat Management Device

• AISI 304 food-grade stainless steel handles significantly higher temperatures than aluminium HMDs. More thermal mass means more stable, even heat distribution across your bowl throughout the session.
• Open-top design eliminates the lid mechanism entirely. You have direct access to your coals for repositioning, adding, or removing — no fiddling with a hot lid. Tong slots are built into the design for easy handling.
• 74 mm bowl contact diameter with a 56 mm inner diameter and 24 mm depth. Fits most phunnel bowls on the market including popular models from Oblako, Kong, and similar manufacturers.
• One-piece construction — machined from a single block of stainless steel. No moving parts, no hinges, no components to break or lose. Built to last indefinitely with basic care.
• Versatile heat range: use 2 coals for a mellow blonde leaf session, or load 3–4 coals for a full dark leaf experience. The stainless steel handles whatever you throw at it.
• Weighs approximately 120 g — substantial enough to sit securely on your bowl without being unwieldy.

Fit and Compatibility

The 74 mm contact diameter seats securely on most standard phunnel bowls. Works well with bowls from Kong, Oblako, BSTD, and similar brands. If your bowl has a lip or ledge designed for HMDs, this will fit.

Care and Maintenance

• Allow the HMD to cool completely before handling — stainless steel retains heat longer than aluminium.
• Rinse with warm water and scrub with a soft brush or sponge. Avoid abrasive tools that could scratch the surface.
• AISI 304 does not oxidise, rust, or form plaque under normal use. A quick rinse after each session keeps it clean.
• For deep cleaning, the device can be heated on an electric stove alongside coals to burn off stubborn residue.
• Store in the included branded wooden box to protect the finish.

In the Box

How is this different from the Kaloud Lotus?

The Na Grani is stainless steel (vs the Lotus's aluminium), open-top (vs the Lotus's adjustable lid), and one-piece construction (vs the Lotus's multi-part design). It handles higher heat, is simpler to use and clean, and will not warp over time. The trade-off is no lid for fine heat adjustment — you control heat by adding or removing coals instead.

Does it work without a lid?

Yes. The open-top design is intentional. Most experienced users find that coal management (adding, removing, repositioning) provides better heat control than a lid. Tong slots are built into the HMD for easy handling.
