Since most of your work is with 0.040" to 0.062" brass for your patchbox material I think those heavy-duty shears are a bit overkill and expensive. Most if not all of my extra material profile removal is done with a cheap Harbor Freight metal bandsaw with a high quality 10 - 14 tooth bi-metal blade. It cuts fast and accurately. I then use files to true up the profile and when there are piercings, I use the ubiquitous Jewlers saw. A wood bandsaw can do the work also using a GOOD bi-metal blade with fine teeth (14 TPI) or a variable tooth pitch - 10 - 14 TPI (on brass or aluminum using the wood bandsaw). Those blades will last you a LONG time and don't waste your money on those cheap carbon steel blades.
