I use to gently tear by hand always inside my plastic container to catch any lost frost. I use to score a round plastic bubble gum container to store my buds in and kept for years. I lost it early 90z going to Dead show at Oakland Colesium The local law was security entering show and big black cop starts patting me and says hey son whats that in your front pocket? I quickly answered chewing tobacco sir....cop pulls can out if pocket and opens. Dat don't look like tobacco to meNever grind, not even for joints.
The grinder keeps the best parts.
Use scissors, and be sure to scrape the edges into the mix after cutting.
4 bongs, use the smaller round nugs that won't shoot straight down the hole as soon as lit.
See if your smoke shop carries "glass pippettes" they're glass one hitters.
