What CS Knot Works Does

We repurpose discarded fly fishing line and retired climbing ropes to make useful and unique items people can enjoy for years to come. Fly fishing line is a very specific and distinctive medium we handcraft into memorable, one-of-a-kind pieces of jewelry and fly fishing equipment. We also work with climbing ropes make long-lasting items for the home, with a fun splash of color. The knots we have mastered reflect a nautical tradition and leave a distinctive look and feel to all of our custom, handmade items.

Fly Fishing Lanyards

Between line colors and patterns, and right down to the corks, no two are the same. 40′ of fly line was never so useful!

Why CS Knot Works?

CS Knot Works was founded by Mark Barsocchini. He describes his work in this way. “My unique style of tying knots allows for pieces that are truly memorable. I recently crafted earrings and cufflinks for a family to honor and remember their father, made from some of his old fly lines. I’ve made one-of-a-kind cufflinks out of fly line for a groom who took his groomsmen on a fly fishing trip. I have also mastered tying retired climbing ropes to make terrific, long lasting statements for the home, all with a fun splash of color.”

From Our Happy Customers

“I absolutely love my earrings from Centennial State Knot Works!! I purchased the sage green, post-style earrings because they are so unique and go with everything! Mark, the creator behind CS Knot Works, told me about how each pair keeps several feet of fly line out of the waste stream and that makes them even more special to me. Thanks for the wearable, sustainable art!”


“Just bought 2 custom lanyards from Centennial State Knot Works for my husband and fishing partner and they love them. Highly recommend Mark, not only is he an outstanding craftsman, but also a great guy. He understood my needs and created a truly custom, one of a kind piece. Delivery was prompt and the presentation in a cigar box was icing on the cake!
Thanks, Mark, indeed a great gift for any fisherman/woman!”


“I love my vintage fly-fishing line earings handmade by Mark!! They are my go-to pair- unique, comfortable, and beautifully made. He is always finding the most gorgeous colors and I appreciate the use of up-cycled materials. I’ll be back for more!!”
