Brother's 3/4-thread overlocker with stepless differential feed and a retractable knife. One reference across five European markets; absent from amazon.com.
The bottom line A well-specified first overlocker, let down only by not being sold in the United States.
Hands-on testing pending. Everything below is either a manufacturer
specification, cited as such, or something we verified ourselves.
What we verified. The reference B06WD4LCNT designates this machine on
amazon.de, .fr, .it, .es and .co.uk, confirmed on EAN in each case. We searched
amazon.com and did not find it: the American results returned the Brother 1034D
and ST4031HD instead. Those are different machines, and we have not published
their references here.
What Brother states. Cutting, sewing and edge-finishing in one pass with
three or four threads. Steplessly adjustable differential feed, which Brother
positions against waving and stretching on elastic and fine fabrics. Rolled
hemming without changing the presser foot or the needle plate. Adjustable
presser foot pressure. Colour-coded internal thread guides, a threading aid for
the lower looper, and the machine supplied already threaded. Free arm or flat
bed. A knife that folds away so you can finish an edge without trimming it.
Listed weight 6.6 kg, three-year manufacturer warranty.
Why “supplied already threaded” is not a throwaway line. An overlocker that
arrives threaded can be re-threaded by tying the new cones to the old tails and
pulling them through, which is far easier than threading from scratch. It is the
difference between a machine used weekly and one used twice.
Where we would look before buying. Maximum speed and the presser foot lift,
neither of which Brother publishes on this listing.

Questions people actually ask
What does a retractable knife actually change?
It lets you overlock an edge without trimming it. Most of the time you want the knife — it is what makes an overlocked seam neat. But on a piece already cut to size, or where you are finishing a raw edge you cannot afford to narrow, a fixed knife forces you to feed the fabric off-line to dodge it. Being able to fold it away turns a two-person balancing act into a normal seam.
Is differential feed worth paying attention to?
It is the single specification that matters most on an overlocker. It drives the front and rear feed dogs at different rates, so it can stop jersey stretching into a wave as it passes under the foot, or deliberately gather a lightweight fabric. Stepless adjustment, as here, means you can dial it rather than pick from three settings.
