Where to find correct knife to fit new BC?

[underachiever]

We just got our first BC's. Seaquest back inflate Malibu. There are a couple of groments on the left side just above the weight pocket that I think are for a knife. Is the Seaquest squeeze knife the only one that will fit? I have only located it on a site across the pond. or will a variety of knives attach easily? and which ones?

Thanks for the help.
