Why buy this
Buy this when a fixed practice lock is no longer enough
Clear locks teach visibility, but a repinnable cutaway teaches progression. You can alter pinning, practise a known problem, and then make the same lock harder as your tension control improves.
Visible but serious
The cutaway window shows the mechanism while the solid body feels more like a real cylinder.
Change the lesson
Repinning lets you rebuild the lock around standard pins, security pins, or specific problem chambers.
Longer bench life
One configurable trainer can stay useful through many stages of practice.
Practice route
How to use a repinnable lock well
Start with fewer chambers and standard pins, then add pins back in as the open becomes repeatable. When you are ready, introduce security pins one at a time so you know exactly what each change feels like.
- Record each pinning setup before you change it.
- Add difficulty slowly so feedback stays readable.
- Use the cutaway view to diagnose, then cover it and repeat.

Questions
Quick answers
Why choose cutaway over clear acrylic?
Cutaway locks give visibility while feeling closer to a metal cylinder.
Is repinning difficult?
It takes care and organisation, but it is exactly what makes the lock a long-term trainer.
Can a beginner use it?
Yes. Start with an easy pinning setup and increase difficulty slowly.
What tools help?
A pinning tray, tweezers, and a clear note of your current pinning make practice cleaner.
Choose Infinitus for a practice lock that keeps changing
It is the training lock for buyers who want visibility, metal feedback, and a way to build harder lessons on the same cylinder.

👍🏻
Color: Black, Army Green, Light Gray, Size: 5X-Large
Weirdly thick material, I wasn’t a fan but it’s a good sleep shirt

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.

Its alright
Color: Black, Size: 5X-Large
True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through).
There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).

Fuzzballs get wearing once
Color: Black, Size: X-Large
Very smart to wear, but the quality is terrible so after one wash the collar start fraying and fuzzballs start forming.
Very disappointing.
