Master Lock padlocks can be tough. Real Tough!
Hit them, pierce them, or pry them; they keep on living with almost supernatural resolve. So how do you defeat the lock with the resilience of the "undead?" The Peterson "Silver Bullet" Bypass Set is just the weapon you need. Inserted through the key-way, our government steel tools release the shackle in two easy steps. Opens Master Lock Model #1, #2, #3 & #4 padlocks in seconds. Withdraws the locking teeth on most Model #5 and # 6 padlocks far enough to insert standard butterfly shims. Get right to the heart of Master Locks with our Silver Bullets! Training DVD highly recommended for use of these tools.
DOES work with the earlier versions with the Blue Master Lock molded band and those that said "tougher than a bullet" are the ones we beat.(and earlier).
Does not work on the later versions (commercial) with the black molded band.
