Alan, many thanks for the response. I was just about to Google Gordian knots and then spotted your update. 


I’ve made several Celtic knot slimline pens. I’m using the cheap pen sets from Amazon while I hone my skills and get my competence up. Then I’ll be heading for the great quality fountain pen kits and the finer woods. I’ll look out for your suggestions otherwise it’s a trip to Oz and smuggling! 

Have a great day / evening.
