okay, so in legend of zelda(edit: Ocarina Of Time), you always have a sword, little do you know, it's actually constantly changing forms.
when you're just carrying it, it can't damage/break/cut anything.

when you press the slash button(B) it initiates a script which does two things: moves your sword in a slashing motion, and allow it to damage/break/cut things.

with this glitch, you'll be able to initiate the damaging half of the script so that while you're carrying your sword, it can damage things.

step 1: equip the kokiri shield and hold it in front of you.

step 2: practise a few stabs with your shield held out (hold R to shield, then press forwards and B to stab.

step 3: find a choppable sign and shield by it so that you can go from sheilding to reading it.

step 4:stab and read the sign at the same time. (note: if done correctly, the sign will pop off as the reading window opens. as you walk around, your sword will kind of leave a green shadow-like thing. if you run into, say grass, just your sword touching it will cut it)

Step 5: (de-activating the glitch) to de-activate this glitch, go to a different map, slash with B or put away your sword.

I hope this helped!
