KnitPro Cubics 13 cm Interchangeable Circular Needle Set: what’s included and what makes it different

If you’re looking for an all-round set with a different feel from traditional round needles, the KnitPro Cubics 13 cm Interchangeable Circular Needle Set stands out thanks to its cubic/square profile: it gives you more control in the hand and helps stop the stitch from “wobbling” as you knit, without losing a smooth glide as the yarn moves.

As for what’s included, this set comes with 7 pairs of 13 cm Cubics tips in 4.00 / 4.50 / 5.00 / 5.50 / 6.00 / 7.00 / 8.00 mm, plus 4 Swivel 360° cables to create total lengths of 60, 80, 80 and 100 cm (with tips attached). This covers everything from smaller garments to projects with lots of stitches, without having loose needles scattered everywhere.

It also includes 8 stoppers, 4 cable keys and 1 set of connectors, and it comes stored in an envelope-style fabric case, with compartments for tips and a zipped pocket for cables and accessories.

How to choose your size and cable with the KnitPro Cubics 13 cm Interchangeable Circular Needle Set

In this kit, the 4.00–8.00 mm range is very much geared towards everyday knitting projects: DK, Worsted/Aran and other medium-weight yarns. To get it right, let your pattern’s swatch guide you: if the fabric feels stiff, go up half a size; if it’s too loose, go down. The beauty of a KnitPro Cubics 13 cm interchangeable circular needle set is that you can adjust without having to buy another fixed circular.

The cables also make a real difference. In this set you have 60 cm (very handy for necklines and smaller projects), 80 cm (the most versatile size) and 100 cm (for lots of stitches, larger shawls or magic loop). Because they’re Swivel 360° cables, the join rotates and helps reduce the cable twist that can build up when you work many rounds in a row.

One more useful detail: the cable ends have holes for using the tightening key, and they can also be used to thread a lifeline (a safety strand) when you want to try the garment on or protect a critical round.

Recommended projects for the KnitPro Cubics 13 cm Interchangeable Circular Needle Set

This set is a particularly good fit if you like projects where tension control matters: top-down jumpers, cardigans, shawls with crisp stitch definition, cabled or textured pieces, and blankets in medium weights. With cubic-shaped needles (in wood), many knitters notice a more stable grip, especially if they tend to knit tightly or get tired with fully round needles.

It’s also a great “core set” if you don’t want to collect fixed circulars: with 7 sizes and 4 lengths you can cover a huge number of patterns without improvising. And if you pause mid-project, the stoppers let you hold stitches safely, without worrying about your work slipping off.

If you’re coming from other KnitPro sets, the approach here is clear: comfortable grip + swivel cable + a tidy case. Exactly what most knitters are after when they want to buy the KnitPro Cubics 13 cm Interchangeable Circular Needle Set as their main set (or as a second set to alternate projects).
