I went into Morris & Sons’ in Sydney to buy some 6.5mm circulars to finish the neck and arm bands for the ‘Ultra Vest’. I explained that I wasn’t sure what length cable I should get and the shop assistant reached for the Knit Pro interchangeable circulars.
The cables come in 40cm, 60cm, and 80cm. The tips come in laminated birch (pictured above), bamboo, ‘metal’, and acrylic. The shop assistant raved about them and said everyone who works at Morris & Sons knit with them. With such a recommendation, I decided to give them a try too: I bought all 3 lengths cables, 1 set of 3.75mm and 1 set of 6.5mm laminated birch (Symfonie).
The key of interchangeable circular needles is the joint that needs to be seamless so as not to catch. The Knit Pro‘s metal joints seem to do that. The cables come with a metal wire key that you insert into a tiny hole in end of the tips to tighten the joint. Each cable also come with two terminating ‘buttons’ that screw onto to the ends to be used as stitch holders. The advantage of that is, of course, when you come to pick up these stitches on the holder, you simply replace one of the buttons with a needle tip and then start knitting (rather than having to transfer the stitches back onto a needle).
I then ordered some Knit Pro bamboo tips (pictured below) for another project to see what they are like. The laminated birch are okay but can be a little ‘sticky’. I have grown to prefer quality bamboo. For circulars, I think both these bamboo tips are better than the standard Addi Click as the surface of the needle has more grip so the stitches don’t slip and slide, but are not as ‘sticky’ as the laminated birch. (Having said that I still prefer the Japanese made Tulip bamboo needles for smoothness with grip.)
Up till now, I have always used fixed circulars because I had only seen interchangeable sold as sets and they just seem like too much investment. Being able to get cables and tips separately as I need them feels less like a commitment, although I am sure it doesn’t work out cheaper. I notice that Addi also has a range of interchangeable bamboo tips and Morris & Sons now also offer Tulip Interchangeables too.
