Oh....I own a whole set of Harmony 10" straights. First off...I love the fact that there was a 10" straight. Hard to find in the "real world" I use them for anything that doesn't require more than a 10" runway.
As mentioned above, they are smooth, light, comfy, pointy enough, and yes....stunning to look at! My best set of straights!!
The 10" really does make a difference. Not so heavy, not hitting my DH in the leg when we are cuddled up on the couch, not hitting the table top if I am knitting at a table.
I use my Denise set for almost everything else...and after that, I use my knit picks or Addi fixed circs for anything smaller. So I get excited when I have a project I can use my harmonies for!
