Here's something I tried to sell to a tying tools and materials companies and never found a buyer. Which is unfortunate because it works great. In fact, when I was attending fly tying demonstration events, I received more positive comments in regards to this devise than I did the patterns I was tying. It's easy to make. All you need is a plastic plate and magnets you purchase at a craft store. You glue the magnets on the bottom of the plate and they hold the catcher to the metal pedestal directly below the vise jaws. The added advantage of the magnets is that they also attract hooks if you drop them on the plate. You can place a paper plate on top of the plastic catcher and toss the paper plate with all the trimmings... this is especially handy at the end of demonstration fly tying. If I see this thing offered by vise and/or tying material companies in the future, I'll be pissed.
