An overlocker is what makes home-sewn clothes stop looking home-sewn. We compare machines on threading (the reason most overlockers sit unused), differential feed and how cleanly they handle stretchy knits.
Overlocker · 2/3/4 thread · 3.1–7.3 mm cut
A convertible 2/3/4-thread overlocker with an adjustable cutting width. One reference on all six markets — but sold as an imported product on every one of them.
Best for: Someone who wants a Janome overlocker and is content to buy an import
≈ $360 / £475 / 535 €
Overlocker · 3/4 thread · 6.6 kg
Brother's 3/4-thread overlocker with stepless differential feed and a retractable knife. One reference across five European markets; absent from amazon.com.
Best for: A first overlocker for knits and garment seams, where threading anxiety is the real obstacle
≈ £240 / 240 €
2/3/4 thread · 34 × 27 × 29.5 cm
Juki's domestic overlocker, available under one reference on all six Amazon stores — and the product that exposed a flaw in our own verification method.
Best for: A first overlocker for knit garments and professional seam finishes
≈ 625 €
3/4 thread · extension table · 3 extra feet
A 3- and 4-thread overlocker sold with an extension table and three additional feet included. One reference across all five European markets, absent from the US.
Best for: A first overlocker for knit garments, where the included table and feet remove the usual follow-up purchases
≈ £350 / 515 €
Overlocker · 2/3/4 thread · three references
Bernette's 2/3/4-thread overlocker with differential feed. Available on all six markets — under three different Amazon references, which is the thing to know before you follow a link.
Best for: Someone who wants the Bernina service network at overlocker money
≈ $700 / £450 / 650 €
Overlocker · 4 thread · 1,300 spm
A four-thread overlocker with automatic lower looper threading and a stated 1,300 stitches per minute. Proven on four markets under three different references; absent from Italy and Spain.
Best for: Someone who has been put off overlockers by threading, and sews enough to want the speed
≈ $750 / £840 / 650 €
The ease of threading and the quality of the knife make all the difference in use on a machine reputed to be hard to get to grips with.
An entry-level model is enough to finish seams neatly and to work out whether the tool has a place in the workshop.
No, never. It makes no straight stitch, no buttonhole, no topstitch. The two machines complement each other.
It is the format's main obstacle, above all at the lower looper. The threading order must be respected strictly, and assisted systems change the experience a great deal.
By knotting the new threads to the old ones and pulling them through the machine. That method avoids rethreading everything at every change of colour.
Four for a strong construction seam on jersey, three for plain overcasting. Most models do both.
A tension imbalance between the loopers, or a thread out of its guide. Check the whole path before touching the dials.
Yes, and a blunt knife chews the fabric instead of cutting it cleanly. A spare part worth knowing about.
Cones of overlocking thread, finer and softer than ordinary machine thread. They go fast: four spools at a time.
On most models yes, and it is useful for overcasting without narrowing the piece. A function to check before buying.
An overlocker complements a sewing machine, it never replaces one. Threading is the real obstacle: respect the order, and knot the new threads to the old to pull them through rather than starting over.
Only the specifications at least four models out of five state. A column that is more empty than full compares nothing.
