Gen 2 Pro Series Expansion Set The Expansion Set is everything the Gen 1 and Gen 2 are missing, and then some. Once you have advanced enough to handle thin picks, this is the set you need to take on the narrowest keyways and tightest warding in locksport. These profiles are purpose built for tight keyways, with micro picks designed for stepping through pins with excellent feedback and awareness. Each pick is laser engraved with reference points, so you always know where the pins sit relative to the keyway. Built from the same industry leading stainless steel as our full Gen 2 line and backed by a lifetime warranty. Includes 10 picks Micro profiles (tight keyways): Micro Short, Micro Medium, Micro Deep, Quad Rake Micro Short rakes: Quint Rake Short, Quad Rake Short Specialty: Staff Pick (not laser engraved), SOF Short, SOF Medium, Double Tap Specifications Handle thickness: 2.5mm Profile thickness: 0.48mm to 0.5mm Profile length: 38mm Profile height: 1mm to 2mm Reviewed by Lock Noob We sent our picks to Lock Noob, a highly respected voice in the lockpicking community, to test across a range of locks. No payment was involved beyond providing the set for review. He found them effective at opening multiple locks and a major improvement over the first generation.
