For a broader read on what to carry, our cordless drill picks cover the tools these knives get used alongside.

If you are shopping budget blades instead of knives, the DeWalt Atomic utility knife situation is worth a look before you spend more.

Availability

Milwaukee has not announced pricing or a ship date. Home Depot is the primary channel for Milwaukee hand tools, so watch store shelves and homedepot.com rather than Amazon, where most Milwaukee listings are third-party.

The one Amazon listing we found for the 48-22-1505 is a two-pack promo, not the standard single knife. We will add the SKUs to the database and link them when retail listings firm up.

Milwaukee’s knife lineup has been crowded for a while. The 6in1 sits above the plain FASTBACK Folding Utility Knife and below the spring-assisted models in price and complexity.

Meanwhile the Compact Side Slide answers a complaint that shows up in every utility knife review section: blades creeping out in a tool bag. If you have ever pulled a knife out of a pouch and found the blade half-deployed, that is the model to look at.

The Compact Side Slide is the safety play. It runs a slide button built to reduce accidental blade activation and retraction, and keeps the all-metal body, tool-free blade change, and wire belt clip.

Rounding out the trio is the Compact Folding Knife, a pocket knife rather than a utility knife: sub-2.5-inch stainless drop point blade, sub-4-inch handle, liner lock.

Six functions on deck: utility knife, wire stripper, 1/4-inch nut driver, PH2 bit, SL 1/4-inch bit, and a bottle opener.

The blade holder has a metal extension to stop accidental blade removal, and there is a scoring feature plus a tether-ready lanyard hole.

The 6in1 is the headline. Milwaukee rebuilt it around an all-metal body and added a press-and-flip mechanism for one-handed opening, which matters when your other hand is holding a sheet of drywall. Tool-free blade changes carry over.

The bit holder and nut driver were redesigned to accept any 1/4-inch bit up to 2 inches, single or double-ended, so you can carry the bits you actually use instead of the two Milwaukee shipped in the box.

Milwaukee announced three new knives on Nov. 6, and one of them is a genuine rethink of the FASTBACK format.

The other two are the kind of quiet pocket-carry updates that matter more than they sound. All three carry the same limited lifetime warranty.
