The grinder is a tool that breaks large lumps of marijuana into fine pieces in order to wrap them in a paper or put them in a bong more efficiently. If you don't have this commercial tool, you can chop the weed in a variety of ways using common household items.
Steps
Method 1 of 4: with scissors and a shot glass
Step 1. Put the marijuana buds you want to chop into a shot
Step 2. Use a pair of scissors to shred them repeatedly for about a minute or until they reach the desired consistency
Method 2 of 4: with a coffee grinder
Step 1. Put the marijuana buds in the coffee grinder
Step 2. Chop them for about five seconds and check their consistency
In this way, you avoid chopping them excessively with the risk of getting too fine a powder.
Step 3. Continue grinding the herb for five seconds at a time until you get the grain you want
Method 3 of 4: with a Knife
Step 1. Place the herb you want to shred on a cutting board or similar base
Step 2. Use a knife to chop it up repeatedly until you get the desired grain
If you want to get the best results, you don't have to use a serrated knife
Method 4 of 4: with a Coin and a Pill Bottle
Step 1. Put the marijuana buds you want to grind into an empty pill bottle
Step 2. Add a clean coin, such as a 5, 10, or 20 cent coin
Step 3. Shake the bowl repeatedly for about five minutes, or longer, until the lumps are completely crushed
The coin breaks and fragments the grass as you shake the bottle.
