Southwest corner punch woes.
I bought a Marvy Uchida Southwest corner punch and I can't get the stupid little thing to work consistently. It's not like it's a high end punch, I only paid a few bucks for it, but it was the only Southwest punch I could find and I really like the look it gives corners WHEN IT WORKS. But I have yet to use it on an actual project because when I test it on scrap it sometimes punches correctly and sometimes doesn't. So it's useless to me. Wah!
Does any other company make this kind of punch?
