The Milwaukee FASTBACK Folding Utility Knife, in its red and black colorway, is a tool that has become a common sight on job sites and in workshops. It’s a folding utility knife with a focus on blade multifunctionality, and it has earned a reputation for being a reliable everyday carry for those who cut frequently. This review looks at how it performs in real-world use, what it does well, and where it falls short.
The primary appeal of the FASTBACK is its blade storage system. Unlike many folding knives that only hold one blade at a time, this model stores an additional five blades in the handle. This is a practical feature for anyone who goes through blades quickly, as it reduces the need to constantly carry a separate blade pack. You simply flip open the rear compartment to access the spares. In practice, this works smoothly and feels secure, with the blades staying in place even when the knife is tossed into a tool bag. The blade change mechanism itself is tool-less, which is a standard convenience but executed well here—you press a button, slide the old blade out, and push a new one in.
The folding design is also worth noting. The knife uses a liner lock to keep the blade open during use, and it feels solid. There is minimal blade play when locked, which is important for controlled cuts. The blade deploys via a thumb stud or a flipper tab, and the action is smooth out of the box. It takes some breaking in to get it truly slick, but it works reliably from day one. The pocket clip is deep carry, meaning the knife sits low in your pocket, and it is reversible for left-handed users. This is a thoughtful touch that not all utility knives offer.
In terms of real-world usage, the FASTBACK handles standard cutting tasks well: opening boxes, cutting drywall, trimming carpet, and slicing through tape or plastic strapping. The standard utility blades are easy to find and replace, and the knife’s weight (just over 5 ounces) gives it a substantial feel without being too heavy for pocket carry. The handle has a rubberized overmold on the metal frame, which provides a decent grip even when your hands are sweaty or dirty. However, the texture is not overly aggressive, so it won’t wear out your pocket lining.
There are, however, limitations to consider. One trade-off is the blade storage compartment: it adds bulk to the handle, making the knife thicker than many simpler folding utility knives. If you prefer a slim profile for pocket carry, this might feel a bit chunky. Additionally, the blade storage mechanism can be finicky if you try to load more than five blades—it works best with the specified capacity. Another point is that the knife is not rust-proof; the metal parts can show corrosion if exposed to moisture over time, so it’s worth wiping it down occasionally if you work in damp conditions.
Compared to a standard retractable utility knife, the FASTBACK offers the convenience of folding and blade storage but lacks the ability to adjust blade depth easily. Retractable knives let you set the blade to a specific length, which is useful for scoring materials or making shallow cuts. The FASTBACK has a fixed blade depth, so you have to adjust your technique or use the entire blade edge. For some users, this is a minor inconvenience; for others, it might be a dealbreaker. A similar alternative would be a basic folding utility knife without blade storage, such as the Husky or Stanley versions, which are lighter and cheaper but require you to carry extra blades separately.
Who is this knife for? It suits tradespeople, DIYers, and anyone who cuts materials regularly and wants to minimize downtime for blade changes. It is also good for those who prefer a folding knife over a retractable one for safety reasons—the blade folds away when not in use. However, it is not ideal for users who prioritize a slim, lightweight pocket knife for occasional tasks, or for those who need precise blade depth control for scoring or detail work. The FASTBACK is a workhorse, not a precision instrument.
Overall, the Milwaukee FASTBACK Folding Utility Knife is a solid tool that delivers on its promise of blade multifunctionality. It is not revolutionary, but it is well-built and practical for its intended use. If you value having spare blades on hand and don’t mind the extra bulk, it is a worthy addition to your toolbox.
