Spy Gadgets that Russia doesn’t want to share with you

physical sabotage against European infrastructure is increasing

I will take you through the world of compact lockpick sets. What makes them good, when do you use them, and why are they so popular among professionals?

Why compact size?

Let me be honest: a full lockpick set with 30+ tools is impressive, but not practical. I have seen sets that are as large as a complete toolbox. Great for home, useless on the go.

Compact sets have emerged out of necessity. Locksmiths need to go to clients. Security auditors visit multiple locations per day. And hobbyists don’t want to carry around a suitcase.

Who are compact sets intended for?

Professionals:

• Locksmiths who receive emergency calls
• Penetration testers who test physical security
• Security consultants who demonstrate vulnerabilities

Hobbyists:

• Locksport practitioners who attend meetups
• People who want to test their own locks
• Collectors of security-related tools

Three types of compact sets

Compact lockpick sets come in different forms. I divide them into three categories:

1. Credit card size

These sets literally fit in a plastic card that fits in your wallet. You click the lockpicks out when you need them. Handy, but be careful: plastic versions are fragile. Don’t use them for daily work.

Advantage: Always with you, goes unnoticed
Disadvantage: Limited number of tools, sometimes less durable

2. Folding knife style

Looks like a Swiss army knife, but with lockpicks instead of knives. The picks fold in and out. Sturdier than credit card sets and you can attach them to your keychain.

Advantage: Durable, easy to carry
Disadvantage: Slightly larger than a credit card

3. Ultra-thin bypass tools

Not traditional lockpicks, but specialized tools for specific locks. Think of bypass cards for pin tumbler locks. Much thinner than normal picks – sometimes only 0.3mm thick.

Advantage: Extremely compact, quick access to certain locks
Disadvantage: Works only for specific lock types

5 Compact sets I would recommend

I won’t give a sales pitch. Below you will find five sets that I have used myself or know are good. Each has pros and cons.

Lockpick Credit Card – For your wallet

The Lockpick Card is a plastic card with four picks and a tension wrench. Just slightly thicker than a bank card.

Contains:

• Diamond Pick
• Long Rake
• Snake Rake
• Hook Pick
• Double-sided Tension Wrench

Honest opinion: Good for emergencies or as a backup. Not your main set. The plastic can break with heavy use. But for 95% of people who “just want to have something on hand,” this is perfect. If you want to use this set, polish the picks a bit. This makes it a decent EDC set.

Sparrows CHAOS Card – The premium version

The CHAOS Card from Sparrows is what you get when you take “credit card size” seriously. Better material, more tools, thinner design.

Why Sparrows? They are an established name within the lockpicking community. Many professionals swear by them. The quality is simply better than cheap alternatives.

Honest opinion: More expensive, but you pay for quality. If you use this daily or work professionally, get this. For hobbyists, the regular credit card version is often enough.

Lockpick Folding Knife – 6 picks in folding knife size

The Lockpick Folding Knife is my personal favorite for daily use. Fits on your keychain, doesn’t look weird, and has everything you need.

Contains 6 picks:

• Half Diamond
• Half Ball
• Snake Rake
• Long Hook
• Short Hook
• Hook Pick
• Plus a tension wrench hidden in the handle

Honest opinion: This is what I would buy myself if I could choose one compact set. Not too big, not too small. Sturdy enough for regular use. The price is between cheap and premium.

SouthOrd JPXS-6 – For professionals

The SouthOrd JPXS-6 is what locksmiths buy. Stainless steel, serrated screw for secure locking, metal handle. This thing will last for years.

Specifications:

• Only 9cm long
• Picks of 0.6mm thick
• Suitable for European locks
• Stainless steel material

Honest opinion: This is not a beginner set. It’s also not cheap. But if you work professionally or are serious about locksport, this is what you want. The quality is simply on another level.

Sparrows Flex Pass – Specialist tool

The Flex Pass is not a lockpick set in the traditional sense. It is a flipper card for manipulating pin tumbler locks. Only 0.3mm thick.

Honest opinion: This is a specialist tool. Not your first purchase. If you know what flipping is and you need this, then you already know. For beginners: skip this and focus on the basics.

How to choose the right set?

I often get the question: “Which one should I buy?” That depends on what you are going to do with it.

Are you a beginner?

Don’t start with a compact set. Really not. Start with a normal beginner lockpick set and transparent practice locks. Learn the basics first.

Why? Compact sets have limited tools. If you don’t know what you’re doing, you’ll just frustrate yourself.

My tip: Learn to pick locks first with a full set. Once you master the basics, then buy a compact set as a supplement. Not as a replacement.

Are you a professional or experienced hobbyist?

Then you probably already know what you need. A few considerations:

• Daily use: Folding knife style (SouthOrd JPXS-6 or similar)
• Backup/emergency: Credit card in your wallet
• Specialist tasks: Flipper cards or other bypass tools

What should you check?

Material: Stainless steel or hardened steel alloy. No plastic for serious work.

Thickness: For European locks, you need 0.6mm or thinner. American locks have more space, but that doesn’t help you here.

Sturdiness: Hinges and closures must be sturdy. If it wobbles when opening, it will break quickly.

Completeness: At least a hook pick, a rake, and a tension wrench. Without those three, you can do little.

Legality: this is what you need to know

I will be very clear here, because this is important.

For professionals

If you work professionally (locksmith, security auditor, penetration tester):

• Always require written permission in advance
• Document every use
• Keep proof of your qualifications
• Only work within your assignment

A verbal “yes, go ahead” is not enough. Get it in writing.

For hobbyists

As a hobby, there are legal options:

• Practice on your own locks – Buy old locks or special practice locks
• Join the locksport community – TOOOL Netherlands organizes meetings where you can practice legally
• Use transparent locks – This way you learn how locks work without risk

Lockpickings is a member of TOOOL Netherlands. We promote responsible use and education, not illegal activities.

Conclusion: Small but powerful

Compact lockpick sets are not a gimmick. They are real tools that professionals use daily. Whether you are a locksmith, working in security, or just interested in how locks work – there is a compact set that suits you.

My main advice:

1. Buy quality. Cheap junk breaks and only frustrates.
2. Learn the basics first. A compact set is an addition, not a starting point.
3. Use it legally. Otherwise, you ruin it for everyone.
4. Start small. You don’t need five different sets.

Finally

In 2025, physical security will be taken seriously again. The EU is actively warning about hybrid threats where physical and digital attacks are combined. This makes knowledge of physical security more relevant than ever.

But remember: sharing knowledge is good, misusing knowledge is wrong. Keep it legal, keep it responsible, and enjoy the learning process.
