A repinnable cutaway practice lock that shows you what your picks feel
The Dangerfield Infinitus is a cut-away training lock built from a genuine American Schlage cylinder, with one face machined open so you can watch the pins move while you pick. Pull the pins, change the order, drop in security pins, and rebuild the lock as many times as you like. The included tweezers make repinning quick, so you can set a fresh challenge whenever the old one gets easy.
A real lock with the side cut open
Most beginners stall because picking happens out of sight. You feel a pin bind, you set it, and you cannot tell whether you got it right. A cutaway lock fixes that. One side of the cylinder is machined away so the pin stacks, the plug, and the shear line are all on show. Now the feedback in your fingers lines up with what your eyes can see, and the work stops being guesswork.
Because it is built from a genuine Schlage cylinder, it picks like the locks you will actually meet on doors, not like a soft trainer that opens to anything. It is solid and heavy in the hand, so it stays put on the bench while you work.
Pick it, then repin it harder
Start with light tension and a hook. Lift one pin at a time, watch it set against the shear line, and turn the plug. When that gets easy, take the cylinder apart with the tweezers, change the pin order, and put it back together for a fresh lock. The tweezers let you place key pins, springs, and security pins without dropping them, which is the part that frustrates people doing it by hand.
When you are ready to step up, drop in serrated and spool security pins. These give false sets that teach you to read a counter-rotation, the same skill you need on real high-security cylinders. One lock keeps giving you new lessons for as long as you keep changing it.
From first set to security pins, on one lock
A cutaway is the fastest way to connect the feel of a pin setting with what is actually happening inside the plug. Repinnable means you never outgrow it: you just set a harder problem.

Tension Tool Set
Tension is the lesson that makes a lock speak. A range of styles helps you find the lightest touch that still holds the plug while you pick.
Dangerfield Praxis Set
Our most popular pro set. Sixteen dual-gauge picks and five tensioners give you the hooks and rakes to work this lock from first set to security pins.
Dangerfield Serenity Picks
Ten bare 301 stainless picks for clean, direct pin feedback. A focused kit if you want to feel the cutaway, not fight your tools.
Beginners Visual Guide
If pin stacks and shear lines are still new, this builds the mental picture so the cutaway makes sense the moment you pick it up.
Quick answers from the LockPickWorld bench
What is a cutaway lock for?
It is a real lock with one side opened up so the pin stacks and shear line are on show as you pick. Beginners learn far faster when the feel in their fingers matches what their eyes can see.
What does repinnable mean here?
You can take the cylinder apart and change the pin order, depths, and pin types, then rebuild it. When a setup gets easy you simply repin it for a fresh, harder challenge.
Do I need my own pins and tools?
The tweezers for repinning are included, along with standard and security pins to swap in. You supply the picks and tension tools, or pair it with one of the sets above.
Is it only for beginners?
Not at all. Beginners use the cutaway view to learn the basics, and experienced pickers repin it with serrated and spool pins to drill false sets and counter-rotation. It grows with you.
Make the invisible part of picking visible
Pick it open with the side cut away, then repin it harder and trust the feedback alone. One lock, the tweezers to rebuild it, and as many fresh challenges as you care to set. Real opens still come down to practice and technique, but this is the bench tool that gets you there faster.
