This 4-piece metal grinder handles the everyday job before a session. A smooth two-finger twist puts the diamond-cut teeth to work, shredding herbs into a fine, even grind, so a vaporizer heats the whole load through properly.

The 4-piece build is where that pays off. Ground herb falls through a sieve into a separate chamber, so you collect it before it turns to dust. Below that, a fine screen gathers pollen in the bottom compartment - a small bonus that builds up over time. A magnetic lid holds the top shut, so it will not pop open in your pocket.

At 40 mm across, 35 mm tall and 80 g it is genuinely compact: small enough to carry with a portable vaporizer, solid enough in metal to take years of daily grinding without the teeth dulling.

Includes:

• 1 × 4-piece metal grinder, 40 × 35 mm
