To Not Shred Tins and Practice Flair

Howdy all! Just was curious if there is a shaker brand that is recommended for practicing flair. I was practicing some tin on tin stuff outside (nest, snatch, etc) over grass and now the lip of the tins are shredded and I cut myself on them. I plan to sand down the tins I have currently but are there any recommendations on Boston shaker brands, or tips on how to reduce the wear and tear beyond "get good"? Thanks!
