I think I understand what you're talking about. I guess I'll know if I'm right, after this post. First of all, I make all of my own creasers, according to the width of the parallel grooves I want. A small rat tail file and emory cloth is needed. Believe it or not, I use the spikes that are used to hold concret forms in place. The shaft and head diameter are perfect for making one, two, or three line creasers. And they fit perfectly into Osbourne creaser or edger handles. Cut the grooves as per your specs, polish them so they are glass smooth and go to work. I've made several over the past 40 years and they work perfectly. If you don't want or have the ability to do this on your own, get in touch with McMillan tool. They can help you out at a price.
