In this video, I’m breaking down why the Klein Tools 27-in-1 Precision Screwdriver has earned a permanent spot in my specialized “grab-and-go” kits. While the classic 14-in-1 is a legend, it’s often too bulky for high-precision safe work or compact organizers like the Veto Pro Pac SC-45.

Klein 27-in-1 Precision Screwdriver

The Compact Powerhouse for Locksmiths

As a professional locksmith, space in your kit is just as valuable as the tools themselves. We’ve all been there—carrying a heavy bag into a job only to realize you’re hunting for one specific bit. While the classic Klein 14-in-1 has been a staple on my belt for years, I’ve recently found something that’s a game-changer for specialized, compact kits: the Klein Tools 27-in-1 Precision Multi-Bit Screwdriver (32327).

I’m currently putting together a high-efficiency mini-kit for basic lock work and safe combination changes, and I needed something that offered maximum versatility without the bulk.

Why I Made the Switch to the Klien 27-in-1

The first thing you notice is the size. Comparing it to the standard 14-in-1, this precision model is considerably slimmer and lighter. It’s designed specifically for those smaller, more delicate tasks we encounter in locksmithing—like working on safe dials, electronic keypad faceplates, and intricate cylinder components.

The Bit System: It uses 3.5mm double-ended bits. Now, these are semi-proprietary, meaning you can’t just swap in your standard 1/4″ hex bits from your impact driver. However, Klein has packed almost everything a locksmith needs into this one handle:

Phillips & Slotted: The basics for most hardware.
Hex & Tamper-Proof Hex: Essential for door closers and commercial trim.
Torx & Tamper-Proof Torx: A must-have for modern electronic locks and security strikes.

The Perfect Fit for the Veto Pro Pac SC-45

I recently did a video on my Veto Pro Pac SC-45 setup. I actually have two of these bags now—one for my pick case and one dedicated to my Safe Change Key Kit.

The problem with my standard screwdrivers? They were just too big for the SC-45’s low-profile pockets. The Klein 27-in-1 solves that problem perfectly. It slides right into the pouch, leaving plenty of room for my change keys and probes.

Pro Tip: I like this tool so much that I’m buying a second one. Having one dedicated to my pick case and one for my safe kit means I’m never “borrowing” tools from one bag to the other. In this business, organization equals speed.
