Hello there, I have a quick question about round knives

Hello, I am new to leathercraft. I have been using the Olfa round knife to cut thick saddle leather, but I am not too happy with this knife. I want to try a round knife, but I want a top-of-the-line tool (cry once...). I realize I cannot get a Terry Knipschield knife anymore, but I wonder if I can find a maker of similar quality that has stock available. I appreciate your guidance and help with this question. Thank you!
