The Catch 13 (or C13 for short) by YoYoFactory is an all-aluminum version of the Catch 22, released in early August of 2009. Being priced at $80 makes it a more economical and less-pricey alternative to the $460 of the titanium-rimmed Catch 22. It doesn't come with hubstacks, but still has hubstack posts with nubs attached. This was due to the hubstacks sometimes causing a pulsating vibration as the yo-yo spun.
