To get shears in Roblox Doors, use exploits or glitches. First, you need to identify the glitch that allows you to obtain the shears. This involves using an ALT account to avoid getting banned.
Next, follow the specific path required to get the shears. This path involves going backwards and avoiding the void. Be very careful as one wrong step can make you fall.
You might need to delete obstacles that block your path. Make sure not to delete necessary items, as this could hinder your progress.
Timing is crucial when using the glitch. Execute it at the right moment to successfully obtain the shears. Keep in mind, shears were originally found out of bounds under The Courtyard but were removed in the Modifiers update.
