[TheForge] Anyone tried to cut 24 gage brass sheet?

[CGRAF]

I have one very similar to the pexto. It leaves a slight dimple at the 
center and a very slight burr. All in all I use it if I need 3 or more 
circles. Fewer and I am good to go with a scribe and a pair of aviation 
snips. Just cut squares 5.25 or so center the scribe at 5 and cut it out.
